+         Make sure that your platform is supported by running some tests.
+]
+
+The library provides a way to get stacktrace from an exception as if the
+stacktrace was captured at the point the exception was thrown. Works even if
+the exception was thrown from a third party binary library.
+
+Link with
+`boost_stacktrace_from_exception` library (or just `LD_PRELOAD` it!) and call
+boost::stacktrace::stacktrace::from_current_exception() to get the trace:
+
+```
+#include <iostream>
+#include <stdexcept>
+#include <string_view>
+#include <boost/stacktrace.hpp>
+
+void foo(std::string_view key);
+void bar(std::string_view key);
+
+int main() {
+  try {
+    foo("test1");
+    bar("test2");
+  } catch (const std::exception& exc) {
+    boost::stacktrace::stacktrace trace = std::stacktrace::from_current_exception();  // <---
+    std::cerr << "Caught exception: " << exc.what() << ", trace:\n" << trace;
+  }
+}
+```
+
+The output of the above sample may be the following:
+
+```
+Caught exception: std::map::at, trace:
+ 0# get_data_from_config(std::string_view) at /home/axolm/basic.cpp:600
+ 1# bar(std::string_view) at /home/axolm/basic.cpp:6
+ 2# main at /home/axolm/basic.cpp:17
+```
+
+With the above technique a developer can locate the source file and the function
+that has thrown the exception without a debugger help. it is especially useful
+for testing in containers (github CI, other CIs), where the developer has no
+direct access to the testing environment and reproducing the issue is
+complicated.
+
+Note that linking with `boost_stacktrace_from_exception` may increase memory
+consumption of the application, as the exceptions now additionally store traces.
+
+At runtime switch boost::stacktrace::this_thread::set_capture_stacktraces_at_throw()
+allows to disable/enable capturing and storing traces in exceptions.
+
+To disable the `boost_stacktrace_from_exception` library builds the
+`boost.stacktrace.from_exception=off` option, for example
+`./b2 boost.stacktrace.from_exception=off`.

+[section MinGW and MinGW-w64 specific notes]
+
+MinGW-w64 and MinGW (without -w64) users have to install libbacktrace for getting better stacktraces. Follow the instruction:
+
+Let's assume that you've installed MinGW into C:\MinGW and downloaded [@https://github.com/ianlancetaylor/libbacktrace libbacktrace sources] into C:\libbacktrace-master
+
+* Configure & build libbacktrace from console:
+    * C:\MinGW\msys\1.0\bin\sh.exe
+    * cd /c/libbacktrace-master
+    * ./configure CC=/c/MinGW/bin/gcc.exe  CXX=/c/MinGW/bin/g++.exe
+    * make
+    * ./libtool --mode=install /usr/bin/install -c libbacktrace.la '/c/libbacktrace-master'
+* Add info to the project-config.jam in the Boost folder:
+    * using gcc : 6 : "C:\\MinGW\\bin\\g++.exe" : <compileflags>-I"C:\\libbacktrace-master\\" <linkflags>-L"C:\\libbacktrace-master\\" ; 
+* Now you can use a header only version by defining *BOOST_STACKTRACE_USE_BACKTRACE* for your project or build the stacktrace library from Boost folder:
+    * b2.exe toolset=gcc-6 --with-stacktrace

+
+Function names may not be resolved after deployment of your application to a different system.
+
+There are multiple ways to deal with that issue if you distribute PDB files along with your application:
+
+* Link your application and shared libraries with a properly set `/PDBALTPATH` flag, for example `/PDBALTPATH:%_PDB%`. See [@https://docs.microsoft.com/en-us/cpp/build/reference/pdbaltpath-use-alternate-pdb-path official documentation for more info].
+* Set the `_NT_ALT_SYMBOL_PATH` or `_NT_SYMBOL_PATH` environment variables of the target system to the path of the PDBs. See [@https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/symbol-path#controlling-the-symbol-path official documentation for more info].

+[section Theoretical async signal safety]
+
+In theory, walking the stack without decoding and demangling should be async signal safe.
+
+In practice, it is not:
+
+* Looks like a page fault while dumping the trace on a containerized/virtualized
+  Windows system has a chance to deadlock. Page fault could happen easily
+  as we have to write the dump either to memory or to a file.
+* On POSIX systems a deadlock could happen if a signal is received when throwing
+  an exception [@https://github.com/boostorg/stacktrace/issues/131 #131].
+  Theoretically this could be worked around by bypassing the mutex locking
+  in C++-runtime at exception throw
+  ([@https://github.com/userver-framework/userver/blob/4246909c99506d3ab34bd130a5154b4acc8e87de/core/src/engine/task/exception_hacks.cpp#L241-L244 sample implementation]
+  in the 🐙 userver framework), or by using a very modern runtime
+  (glibc-2.35+ with [@https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71744#c32 modern]
+  libgcc or [@https://reviews.llvm.org/D130668 modern] LLVM's libunwind).
+* `-fomit-frame-pointer` like flags add additional complexity to the stack
+  walking implementation, which may also negatively affect the signal safety.
+
+As a rule of thumb: do *not* capture stack traces in signal handlers unless you
+are absolutely sure in your environment and inspected all of its source codes.
