+= Acknowledgements
 
 The first Boost.Process draft was created in 2006. A lof of people have worked on various drafts since then. Especially Merino Vidal, Ilya Sokolov and Felipe Tanus spent a lot of time working on early drafts. They influenced Boost.Process over the years and wrote code which, to various extents, is still around in the library today.
 
 The design of earlier versions of Boost.Process was not always satisfying. In 2011 Jeff Flinn proposed the executor and initializer concepts Boost.Process is based on today. Without Jeff's idea the overall design of Boost.Process would not look like it does today.
 
-A special thank you goes to [@http://www.intra2net.com/ Intra2net AG] (especially Thomas Jarosch) who sponsored a project to support the development of Boost.Process. It was this sponsorship which made it possible to create a new Boost.Process version in 2012.

-[section:design Design Rationale]
-[section Scope]
-This library is meant to give an wrapper around the different OS-specific methods
-to launch processes. Its aim is to provide all functionality that is available on 
-those systems and allow the user to do all related things, which require using the OS APIs.
-
-[*This library does not try to provide a full library for everything process related] 
-In many discussions the proposal was made to build boost.process into a DSEL [footnote Domain Specific Embedded Language] of some sort. 
-This is not the goal, it rather provides the facilities to build such a DSEL-Library on top of it. 
-Therefore the library also does [*not] force any particular use (such as only asynchronous communication) on its user. 
-It rather could be integrated with such a library.  
-
-[endsect] 
-[section Interface Style]
-
-Boost.Process does use a very particular style when constructing a process.
-This is because a process holds many properties, which are not members of the actual child class. 
-Those properties are in many cases not accessible by the father process, for example when using environments. 
-Here the child process can modify its own environment, but there is no way for the father process to know.
-That means, that a child process has properties that cannot be accessed in C++.
-
-This now leads to the two styles supported and mixed by this library. Overloading and properties. 
-Consider that you may want to launch a process passing a number of arguments. This is supported in both styles, and would look like this:
-
-```
-system("gcc", "--version"); //overloading
-system("gcc", args={"--version"}); //property style.
-```
-
-Both styles can also be mixed in some cases.
-
-```
-system("gcc", "-c", args+={"main.cpp"});
-```
-
-In the following section the avaible styles will be described. Note that the
-overload style is implemented via type traits, so the types will be listed. 
-
-[caution There is no guarantee in which order the arguments will be applied! 
-There is however a guarantee for arguments belonging together, i.e. the string 
-argument and the args property will be evaluated in the order given.]
-
-[endsect]
-[section:arg_cmd_style Arguments/Command Style]
-
-When passing arguments to the process, two styles are provided, the cmd-style and the exe-/args-style. 
-
-The cmd style will interpret the string as a sequence of the exe and arguments and parse them as such, while the exe-/args-style will
-interpret each string as an argument.
-
-[table:id Cmd vs Exe/Args
-    [[String]              [Cmd]       [Exe/Args]]
-    [["gcc --version"]     [{"gcc", "--version"}]     [{"\\"gcc --version\\""}]]
-] 
-
-When using the overloading variant, a single string will result in a cmd interpretation, 
-several strings will yield a exe-args interpretation. Both version can be set explicitly:
-
-```
-system("grep -c false /etc/passwd"); //cmd style
-system("grep", "-c", "false", "/etc/passwd"); //exe-/args-
-
-system(cmd="grep -c false /etc/passwd"); //cmd style
-system(exe="grep", args={"-c", "false", "/etc/passwd"}); //exe-/args-
-```
-
-[note If a '"' sign is used in the argument style, it will be passed as part of the argument.
-If the same effect it wanted with the cmd syntax, it ought to be escaped, i.e. '\\\"'. ]
-[note On windows the path will only be searched for the executable in the command style.]
-[endsect]
-
-[section:plat_ext Extensions]
-
-The simplest form to extend functionality is to provide another handler, which 
-will be called on the respective events on process launching. The names are:
-
-*`boost::process::on_setup`
-*`boost::process::on_error`
-*`boost::process::on_success`
-
-
-As an example:
-
-```
-child c("ls", on_setup([](){cout << "On Setup" << endl;});
-```
-
-
-[note On posix all those callbacks will be handled by this process, not the created one. 
-This is different for the posix extensions, which can be executed on the forked process.]

+== Environment
+
+The `environment` namespace provides all sorts of facilities to query and manipulate the environment of the current process.
+
+The api should be straight forward, but one oddity that needs to be pointed out is, that environment names
+are not case sensitive on windows. The key_traits class implements the proper traits depending on the current system.
+
+Additionally, environment can be lists separated by `:` or `;`; `environment::value` and
+`environment::value_view` can be used to iterate those.
+
+Beyond that, the requirements on an environment are a low as possible; 
+an environment is either a list of strings or a list of string-pairs. It is however recommended to use the environment types,
+as to have the right value comparisons.
+
+To note is the `find_executable` functions, which searches in an environment for an executable.

-[section:dead_lock Why does this produce a deadlock?]
-
-Now let's revisit our c++filt example and we will put in an obvious mistake.
-This might however be not as obvious for more complex applications.
-
-```
-vector<string> demangle(vector<string> in)
-{
-    
-    ipstream is;
-    opstream os;
-    child c("c++filt", std_out > is, std_in < os);
- 
-    vector<string> data;   
-    for (auto & elem : data)
-    {
-        string line;
-        getline(is, line);
-        os << elem;
-    }
-}
- 
-```
-We switched the read and write operation up, so that's causing a dead-lock.
-This locks immediately. This is because `c++filt` expects input, before 
-outputting any data. The launching process on the other hand wait's for it's output.
-
-[endsect]
-
-[section:closep Why does the pipe not close?]
-
-Now for another example, which might look correct, let's consider you want
-to use `ls` to read the current directory.
-
-```
-ipstream is;
-child c("ls", std_out > is);

-std::string file;
-while (is >> file)
-    cout << "File: " << file << endl;
-   
-``` 
-
-This will also deadlock, because the pipe does not close when the subprocess exits.
-So the `ipstream` will still look for data even though the process has ended.
-
-[note It is not possible to use automatically pipe-closing in this library, because 
-a pipe might be a file-handle (as for async pipes on windows).]
-
-But, since pipes are buffered, you might get incomplete data if you do this:
-
-```
-ipstream is;
-child c("ls", std_out > is);
-
-std::string file;
-while (c.running())
-{   
-    is >> file;
-    cout << "File: " << file << endl;
-}
-```
-
-It is therefore highly recommended that you use the asynchronous api if you are
-not absolutely sure how the output will look.

-[section:wchar_t When will the codecvt be used?]
-
-Since windows does not use UTF-8 it is sometimes unavoidable to use the `wchar_t` version of the WinApi.
-To keep this library consistent it provides `wchar_t` support on posix also.
-
-Since the posix api is purely `char` every `wchar_t` based type will be converted into `char`.
-
-Windows on the other hand is more selective; the default is to use `char`, 
-but if any parameter requires `wchar_t`, everything will be converted to `wchar_t`.
-This also includes `boost::filesystem::path`. Additionally, if the system does not provide
-the `char` api (as is the case with Windows CE) everything will also be converted.

-[section:introduction Introduction]

-Boost.Process is a library to manage system processes. It can be used to:
-
-* create child processes
-* setup streams for child processes
-* communicate with child processes through streams (synchronously or asynchronously)
-* wait for processes to exit (synchronously or asynchronously)
-* terminate processes
-
-Here's a simple example of how to start a program with Boost.Process:
-
-[def ipstream  [classref boost::process::ipstream ipstream]]
-[def system [funcref boost::process::system system]]
-[def std_out [globalref boost::process::std_out std_out]]
-[def boost/process.hpp [headerref boost/process.hpp boost/process.hpp]]
-
-
-[import ../example/intro.cpp]
-[intro]
-
-[caution This is not yet an official Boost C++ library. It wasn't reviewed and can't be downloaded from [@http://www.boost.org/ www.boost.org]. It is however the latest version of an ongoing effort to create a process management library for Boost. For now the library can be downloaded or cloned from here [@https://github.com/klemens-morgenstern/boost-process/tree/develop https://github.com/klemens-morgenstern/boost-process/tree/develop].]

+
+A launcher is invoked through the call operator.
+
+[source,cpp]
+----
+auto l = windows::as_user_launcher((HANDLE)0xDEADBEEF);
+asio::io_context ctx;
+boost::system::error_code ec;
+auto proc = l(ctx, ec, "C:\\User\\boost\\Downloads\\totally_not_a_virus.exe", {});
+----
+
+The launcher will call certain functions on the initializer if they're present, as documented below.
+The initializer are used to modify the process behaviour.
+
+
+== Linux Launchers
+
+The default launchers on linux open an internal pipe to communicate errors that occur after forking back to the parent process.
+
+NOTE: A pipe can be used if one end is open on the parent, the other on the child.
+This allows the parents to select on his pipe-end to know if the child exited.
+
+This can be prevented by using the `fork_and_forget_launcher`. 
+Alternatively, the `vfork_launcher` can report errors directly back to the parent process.
+
+Thus some calls to the initializers occur after forking from the child process.
+
+[source,cpp]
+----
+struct custom_initializer
+{
+    // called before a call to fork. A returned error will cancel the launch.
+    template<typename Launcher>
+    error_code on_setup(Launcher & launcher, const filesystem::path &executable, const char * const * (&cmd_line));
+
+    // called for every initializer if an error occurred during setup or process creation
+    template<typename Launcher>
+    void on_error(Launcher & launcher, const filesystem::path &executable, const char * const * (&cmd_line),
+                  const error_code & ec);
+
+    // called after successful process creation
+    template<typename Launcher>
+    void on_success(Launcher & launcher, const filesystem::path &executable, const char * const * (&cmd_line));
+
+    // called for every initializer if an error occurred when forking, in addition to on_error.
+    template<typename Launcher>
+    void on_fork_error(Launcher & launcher, const filesystem::path &executable, const char * const * (&cmd_line),
+                       const error_code & ec);

+
+
+    // called after a failed call to execve from the child process.
+    template<typename Launcher>
+    void on_exec_error(Launcher & launcher, const filesystem::path &executable, const char * const * (&cmd_line));

+
+The call sequence when exec fails:

+
+The launcher will close all non-whitelisted file descriptors after `on_exec_setup`.
+
+== Windows Launchers
+
+Windows launchers are pretty straight forward, they will call the following functions on the initializer if present.
+
+[source,cpp]
+----
+struct custom_initializer
+{
+    // called before a call to CreateProcess. A returned error will cancel the launch.

+    void on_success(Launcher & launcher, const filesystem::path &executable, std::wstring &cmd_line);

+= Quickstart
+
+A process needs four things to be launched:
+
+* an asio execution_context / executor 
+* a path to an executable
+* a list of arguments
+* a variadic set of initializers
+
+.example/quickstart.cpp:13-17
+[source,cpp,indent=0]
+----
+include::../example/quickstart.cpp[tag=cp]
+----
+<1> The executor for the process handle
+<2> The Path to the executable
+<3> The argument list in the form of an `std::initializer_list`.
+<4> Not additional initializers
+
+The started process can then be awaited or terminated.
+
+==  Lifetime
+
+If the process handle goes out of scope, it will terminate the subprocess.
+You can prevent this, by calling `proc.detach()`; do however note that this 
+can lead to zombie processes.
+
+A process that completed will deliver an exit-code, 
+which can be obtained by calling `.exit_code` on the exited process and which is
+also returned from `.wait()`.
+
+.example/quickstart.cpp:22-23
+[source,cpp, indent=0]
+----
+include::../example/quickstart.cpp[tag=ls]
+----
+
+The normal exit-code is what the subprocess returned from `main`;
+posix will however add additional information about the process.
+This is called the `native_exit_code`.
+
+
+The `.running()` function can be used to detect if the process is still active.
+
+
+== Signalling the subprocess
+
+The parent process can signal the subprocess demanding certain actions.
+
+`.terminate` will cause the subprocess to exit immediately (`SIGKILL` on posix).
+This is the only reliable & portable way to end a subprocess.
+
+.example/quickstart.cpp:28-29
+[source,cpp,indent=0]
+----
+include::../example/quickstart.cpp[tag=terminate]
+----
+
+`.request_exit` will ask the subprocess to shutdown (`SIGTERM` on posix),
+which the subprocess might ignore.
+
+.example/quickstart.cpp:34-36
+[source,cpp]
+----
+include::../example/quickstart.cpp[tag=request_exit]
+----
+
+`.interrupt` will send an SIGINT to the subprocess, which a subprocess might 
+interpret as a signal for shutdown.
+
+WARNING: interrupt requires the initializer `windows::create_new_process_group` to be set on windows
+
+.example/quickstart.cpp:41-43
+[source,cpp]
+----
+include::../example/quickstart.cpp[tag=interrupt]
+----
+
+[endsect]
+
+[section:execute Execute functions]
+
+Process v2 provides  `execute` and `async_execute` functions that can be used for managed executions.
+
+.example/quickstart.cpp:48
+[source,cpp]
+----
+include::../example/quickstart.cpp[tag=execute]
+----
+
+The async version supports cancellation and will forward cancellation types as follows:
+
+- `asio::cancellation_type::total`    -> interrupt
+- `asio::cancellation_type::partial`  -> request_exit
+- `asio::cancellation_type::terminal` -> terminate

+=== `environment`
+
+The `environment` header provides facilities to maniuplate the current environment and set it for new processes.
+
+
+An environment is a a `range` of `T` fulfilling these requirements:
+
+For `T value`
+  *  - std::get<0>(value) must return a type comparable to `key_view`.
+  *  - std::get<1>(value) must return a type convertible to `value_view`.

+= stdio
+
+When using io with a subprocess, all three standard streams (stdin, stdout, stderr) get set for the child-process.
+The default setting is to inherit the parent process.
+
+This feature meant to be flexible, which is why there is little checking on the arguments assigned to one of those streams. 
+

-[section:tutorial Tutorial]
-
-In this section we will go step by step through the different features of
-boost.process. For a full description see the __reference__.
-
-[section Starting a process]
-
-We want to start a process, so let's start with a simple process. We will
-invoke the gcc compiler to compile a simple program.
-
-With the standard library this looks like this.
-
-```
-int result = std::system("g++ main.cpp"); 
-```
-
-Which we can write exactly like this in boost.process.
-
-```
-namespace bp = boost::process; //we will assume this for all further examples
-int result = bp::system("g++ main.cpp");
-```
-
-The first thing we can do, is to separate the command and the executable into
-two parts, so it is more readable and can be built by a function.
-
-```
-int result = bp::system("g++", "main.cpp");
-```
-
-With that sytax we still have "g++" hard-coded, so let's assume we get the string
-from an external source as `boost::filesystem::path`, we can do this too.
-
-```
-boost::filesystem::path p = "g++"; //or get it from somewhere else.
-int result = bp::system(p, "main.cpp");
-```
-
-Now, there is a subtle difference between the two syntaxes, i.e. passing a
-single string or passing multiple. When passing multiple string, the first string will be
-interpreted as the name of a file and the rest as arguments; 
-when passing one string it will be interpreted as a command. 
-
-For more details please see the [link boost_process.design.arg_cmd_style design description].
-
-[endsect]
-
-[section:launch_mode Launch functions]
-
-Given that in our example used the [funcref boost::process::system system] function, 
-our program will wait until the child process is completed. This is unwanted, 
-especially since compiling can take a while. 
-
-In order to avoid that, boost.process provides several ways to launch a process.
-Besides the already mentioned [funcref boost::process::system system] function,
-we can also use the [funcref boost::process::spawn spawn] function or the
-[classref boost::process::child child] class.
-
-The [funcref boost::process::spawn spawn] function launches a process and 
-immediately detaches so, so no handle will be returned and the process will be ignored.
-This is not what we need for compiling, but maybe we want to entertain the user,
-while compiling:
-
-```
-bp::spawn("chrome", boost_org);
-```
-
-Now for the more sensible approach for compiling, we want a non-blocking execution. 
-To implement that, we directly call the constructor of [classref boost::process::child child].
-
-```
-bp::child c("g++", "main.cpp");
-
-while (c.child_running())
-    do_some_stuff();
-
-c.child_wait(); //wait for the process to exit   
-int result = c.child_exit_code();
-```
-
-So we launch the process, by calling the child constructor. Then we check and do other
-things while the process is running and afterwards get the exit code. The call 
-to child_wait is necessary, to obtain it and tell the operating system, that no
-one is waiting for the process anymore.
-
-[note You can also wait for a time span or a until a time point with __wait_for__ and __wait_until__]
-
-[warning If you don't call wait on a child object, it will be terminated on destruction.
-This can be avoided by calling __detach__ beforehand]  
-
-[endsect]
-[section:error_handling Error]
-
-Until now, we have assumed that everything works out, but it is not impossible, 
-that "g++" is not present. That will cause the launch of the process to fail.
-The default behaviour of all functions is to throw an 
-[@http://en.cppreference.com/w/cpp/error/system_error std::system_error] on failure.
-As with many other functions in this library, passing an [@http://en.cppreference.com/w/cpp/error/error_code std::error_code]
-will change the behaviour, so that instead of throwing an exception, the error will be a assigned to the error code.
-
-```
-std::error_code ec;
-bp::system c("g++", "main.cpp", ec);
-```
-[endsect]
-[section:io Synchronous I/O]
-
-In the examples given above, we have only started a program, but did not consider the output. 
-The default depends on the system, but usually this will just write it to the same output as the launching process.
-If this shall be guaranteed, the streams can be explicitly forwarded like this.
-
-```
-   bp::system("g++", bp::std_out > stdout, bp::std_err > stderr, bp::std_in < stdin);
-``` 
-
-Now for the first example, we might want to just ignore the output, which can be done by redirecting it to the null-device.
-This can be achieved this way:
-
-```
-bp::system("g++", "main.cpp", bp::std_out > bp::null);
-```
-
-Alternatively we can also easily redirect the output to a file:
-
-```
-bp::system("g++", "main.cpp", bp::std_out > "gcc_out.log");
-```
-
-Now, let's take a more visual example for reading data. 
-[@http://pubs.opengroup.org/onlinepubs/009696699/utilities/nm.html nm] is a tool on posix, 
-which reads the outline, i.e. a list of all entry points, of a binary. 
-Every entry point will be put into a single line, and we will use a pipe to read it. 
-At the end an empty line is appended, which we use as the indication to stop reading.
-Boost.process provides the pipestream ([classref boost::process::ipstream ipstream], 
-[classref boost::process::opstream opstream], [classref boost::process::pstream pstream]) to
-wrap around the [classref boost::process::pipe pipe] and provide an implementation of the 
-[@http://en.cppreference.com/w/cpp/io/basic_istream std::istream],
-[@http://en.cppreference.com/w/cpp/io/basic_ostream std::ostream] and 
-[@http://en.cppreference.com/w/cpp/io/basic_iostream std::iostream] interface.
-
-```
-std::vector<std::string> read_outline(std::string & file)
-{
-    bp::ipstream is; //reading pipe-stream
-    bp::child c("nm", file, bp::std_out > is);
-    
-    std::vector<std::string> data;
-    std::string line;
-    
-    while (c.child_running() && std::getline(is, line) && !line.empty())
-        data.push_back(line);    
-        
-    c.child_wait();
-    
-    return data; 
-}
-```
-
-What this does is redirect the `stdout` of the process into a pipe and we read this
-synchronously.
-
-[warning The pipe will cause a deadlock if you try to read after nm exited]
-[note You can do the same thing with [globalref boost::process::std_err std_err]] 
-
-Now we get the name from `nm` and we might want to demangle it, so we use input and output.
-`nm` has a demangle option, but for the sake of the example, we'll use 
-[@https://sourceware.org/binutils/docs/binutils/c_002b_002bfilt.html c++filt] for this.
-
-```
-bp::opstream in;
-bp::ipstream out;
-
-bp::child c("c++filt", std_out > out, std_in < in);
-
-in << "_ZN5boost7process8tutorialE" << endl;
-std::string value;
-out >> value;
-
-c.child_terminate();
-```
-
-Now you might want to forward output from one process to another processes input.
-
-```
-std::vector<std::string> read_demangled_outline(const std::string & file)
-{
-    bp::pipe p;
-    bp::ipstream is;
-    
-    std::vector<std::string> outline;
-    
-    //we just use the same pipe, so the 
-    bp::child nm("nm", file, bp::std_out > p); 
-    bp::child filt("c++filt", bp::std_in < p, bp::std_out > is);
-    
-    while (nm.running()) //nm finishes automatically, so then we can terminate c++filt.
-    {
-        std::string line;
-        std::getline(is, line);
-        outline.push_back(line);
-    }
-    nm.child_wait();
-    filt.child_terminate(); 
-}
-
-```  
-
-Now this forwards the data from `nm` to `c++filt` without your process needing to do anything.
-
-[endsect]
-[section:async_io Asynchronous I/O]
-
-Boost.process allows the usage of boost.asio to implement asynchronous I/O. 
-If you are familiar with [@http://www.boost.org/doc/libs/release/libs/asio/ boost.asio] (which we highly recommend), 
-you can use [classref boost::process::async_pipe async_pipe] which is implemented 
-as an I/O-Object and can be used like [classref boost::process::pipe pipe] as shown above.
-
-Now we get back to our compiling example. `nm` we might analyze it line by line,
-but the compiler output will just be put into one large buffer.
-
-With [@http://www.boost.org/doc/libs/release/libs/asio/ boost.asio] this is what it looks like.
-
-```
-io_service ios;
-std::vector<char> buf;
-
-bp::async_pipe ap(ios);
-
-child c("g++", "main.cpp", bp::std_out > ap);
-
-asio_async_read(ap, asio_buffer(buf), 
-                [](const boost::system::error_code &ec, std::size_t size){});
-
-ios.run();
-c.wait();
-int result = c.exit_code();
-```
-
-To make it easier, boost.process provides simpler interface for that, so that the buffer can be passed directly, 
-provided we also pass a reference to an io_service. 
-
-```
-io_service ios;
-std::vector<char> buf;
-
-child c("g++", "main.cpp", bp::std_out > asio_buffer(buf), ios);
-
-ios.run();
-c.wait();
-int result = c.exit_code();
-```
-
-[note Passing an instance of io_service to the launching function automatically cause it to wait asynchronously for the exit, so no call of 
-[memberref boost::process::child::wait wait] is needed]
- 
-To make it even easier, you can use [@http://en.cppreference.com/w/cpp/thread/future std::future] for asynchronous operations
-(you will still need to pass a reference to a io_service) to the launching function, unless you use bp::system.
-
-Now we will revisit our first example and read the compiler output asynchronously:
-
-```
-boost::asio::io_service ios;
-
-std::future<std::string> data;
-
-child c("g++", "main.cpp", //set the input
-        bp::std_in.close(), 
-        bp::std_out > bp::null, //so it can be written without anything
-        bp::std_err > data, 
-        ios);
-
-
-ios.run(); //this will actually block until the compiler is finished
-
-auto err =  fut.get();
-```
-
-[endsect]
-[section:group Groups]
-
-When launching several processes, processes can be grouped together. 
-This will also apply for a child process, that launches other processes, 
-if they do not modifiy the group membership. E.g. if you call `make` which 
-launches other processes and call terminate on it, 
-it will not terminate all the child processes of the child unless you use a group.
-
-```
-bp::group g;
-bp::child c1("foo", g);
-bp::child c2("bar", g);
-g.group_terminate();
-```
-
-Please see to the [headerref boost/process/group.hpp reference] for more information.
-
-[endsect]
-[section:env Environment]
-
-This library provides access to the environment of the current process and allows
-setting it for the child process.
-
-```
-//get a handle to the current environment
-auto env = boost::this_process::environment();
-//add a variable to the current environment
-env["VALUE_1"] = "foo";
-
-//copy it into a environment seperate to the one of this process
-bp::environment env_ = env;  
-//add a value only to the new env
-env_["VALUE_2"] = "bar";
-
-//launch a process with `env_`
-bp::system("stuff", env_); 
-```
-
-A more convenient way to modify the environment for the child is the 
-[globalref boost::process::env env] property.
-
-Please see to the [headerref boost/process/environment.hpp reference] for more information.

-
-[note This section presumes knowledge of the boost.asio 
-[@http://www.boost.org/doc/libs/release/doc/html/boost_asio/overview/core/coroutine.html stackless coroutine] feature.]
-
-Stackless coroutines can be implemented rather easily, so there is no need to
-implement extra functionality concerning boost.process. 
-
-```
-struct stackless_t : boost::asio::coroutine
-{
-    bp::child c;
-
-    boost::asio::io_service & ios;
-

-        {

-                    bp::on_exit=

-        }
-    }
-};
-///post the coroutine to a io-service and run it
-int main()
-{

-
-[note This section presumes knowledge of the boost.asio 
-[@http://www.boost.org/doc/libs/release/doc/html/boost_asio/overview/core/spawn.html stackful coroutine] feature.]
-
-For stackful coroutines this is not as simple, because the members of 
-`boost::asio::yield_context` are not documented. Therefore, boost.process 
-provides a simple way to use stackful coroutines, which looks as follows:
-
-```
-void cr(boost::asio::yield_context yield_)
-{
-    bp::system("my-program", yield_);
-}
-```
-
-This will automatically suspend the coroutine until the child process is finished.

+= Version 2
+
+Boost.process V2 is an redesign of boost.process, based on previous 
+design mistakes & improved system APIs.
+
+The major changes are
+
+* Simplified interface
+* Reliance on pidfd_open on linux
+* Full asio integration
+* Removed unreliable functionality
+* UTF8 Support
+* separate compilation
+* fd safe by default
+
+Version 2 is now the defauled. In order to discourage usage of the deprecated v1, it's documentation has been removed.
+
+== Simplified Interface
+
+In process v1 one can define partial settings in the constructor of the process, 
+which has lead to a small DSL.
+
+[source,cpp]
+----
+child c{exe="test", args+="--help", std_in < null(), env["FOO"] += "BAR"};
+----
+
+While this looks fancy at first, it really does not scale well with more parameters.
+For process v2, the interfaces is simple:
+
+[source,cpp]
+----
+extern std::unordered_map<std::string, std::string> my_env;
+extern asio::io_context ctx;
+process proc(ctx, "./test", {"--help"}, process_stdio{nullptr, {}, {}}, process_environment(my_env));
+----
+
+Every initializer addresses one logical component (e.g. stdio) instead of multiple ones accumulating.
+Furthermore, every process has a path and arguments, instead of a confusing mixture of cmd-style and 
+exe-args that can be randomly spread out.
+
+
+== `pidfd_open`
+
+Since process v1 came out, linux has moved along and added [pidfd_open](https://man7.org/linux/man-pages/man2/pidfd_open.2.html)
+which allows users to obtain a descriptor for a process.
+This is much more reliable since it is not as easy to miss as a `SIGCHLD`.
+Windows has provided `HANDLE`s for processes all along.
+Unless the OS doesn't support it, process v2 will use file descriptors and handles to implement waiting 
+for processes.
+
+== Full asio integration
+
+Process v1 aimed to make asio optional, but synchronous IO with subprocesses usually means one is begging 
+for deadlocks.
+Since asio added pipes in boost 1.78, boost process V2 is fully asio based and uses it's pipes and 
+file-handles for the subprocess.
+
+== Unreliable functionality
+
+Certain parts of boost.process were not as reliable as they should've been. 
+
+This concerns especially the `wait_for` and `wait_until` functions on the process.
+The latter are easy to do on windows, but posix does not provide an API for this. 
+Thus the wait_for used signals or fork, which was all but safe. 
+Since process v2 is based on asio and thus supports cancellation, 
+a wait_for can not safely be implemented with an async_wait + timeout.
+
+== UTF-8
+
+Instead of using ascii-APIs on windows, process V2 just assumes UTF-8 everywhere
+and uses the UTF-16 APIs.
+
+== Fd safe by default
+
+While not a problem on windows (since HANDLEs get manually enabled for inheritance),
+posix systems create a problem with inheriting file handles by default.
+
+Process V2 will automatically close all non-whitelisted descriptors, 
+without needing any option to enable it.
+
