+## Description
+
+PPLX is a trimmed version of PPL ([Parallel Patterns Library](https://msdn.microsoft.com/en-us/library/dd492418.aspx), Microsoft's offering for task parallelism, parallel algorithms and containers for C++), featuring only tasks and task continuations, with plain vanilla thread pool implementation underneath. Officially PPLX comes bundled within [C++ REST SDK](https://github.com/Microsoft/cpprestsdk), a cross-platform library from Microsoft for creating REST services. If you use something else for REST, but still want to utilize PPLX for generic concurrency, you have to include C++ REST SDK in its entirety, which is weird.
+
+This project is an extraction of PPLX out of C++ REST SDK, presenting it in a form of a shared or static library. It is of some value for *\*nix* systems, where you don't have the luxury of using the full-fledged version – PPL<sup>[[1]](#r1 "Task Parallelism in C++: Patience. Trust. And Hope.")</sup>.
+
+## How
+
+What was done was basically extracting the minimum code subset representing PPLX out of a specific version of C++ REST SDK (refer to [``CMakeLists.txt``](./CMakeLists.txt) for the exact version number). While I tried to avoid touching the code base as much as possible, some adjustments still slipped in. Particularly, a few preprocessor include statements went through path and file name corrections due to header file relocations. For example:
+
+```cpp
+#include "cpprest/details/cpprest_compat.h"
+```
+
+has become:
+
+```cpp
+#include "compat.h"
+```
+
+## Build
+
+### Requirements
+
+* GCC >= 4.8, Visual Studio >= 2015
+* CMake >= 3.2
+* Boost Libraries >= 1.56
+
+### Steps
+
+Prepare CMake environment appropriately:
+
+```commandline
+$ mkdir build
+$ cd build
+$ cmake ..
+```
+
+Build via ``make`` on *\*nix* side:
+
+```commandline
+$ make
+$ sudo make install
+```
+
+Build via VS on *Windows*:
+
+* Open the corresponding solution in Visual Studio, run build appropriately;
+* Copy the resultant DLL into a directory within your library search path.
+
+## Examples
+
+The concurrency model of PPL is quite similar to the one coming from the C++ Standard Library, with a slight skew towards the notion of task<sup>[[2]](#r2 "Microsoft Concurrency Runtime: Task Parallelism")</sup>. E.g. you launch an asynchronous operation by just creating a new task object (as opposed to an [`std::async<>`](https://en.cppreference.com/w/cpp/thread/async) call), and you basically deal with task objects rather than [*futures*](https://en.cppreference.com/w/cpp/thread/future). In the following example we'll obtain the angle between two Euclidean vectors from their dot product and magnitudes calculated concurrently.
+
+```cpp
+#include <algorithm>
+#include <iostream>
+#include <vector>
+#include <cmath>
+#include <pplx/pplxtasks.h>
+
+int calcDotProduct(const std::vector<int>& a, const std::vector<int>& b)
+{
+  return std::inner_product(a.begin(), a.end(), b.begin(), 0);
+}
+
+double calcMagnitude(const std::vector<int>& a)
+{
+  return std::sqrt(calcDotProduct(a, a));
+}
+
+int main()
+{
+  // To keep things simple let's assume we deal with non-zero vectors only.
+  const std::vector<int> v1 { 2, -4, 7 };
+  const std::vector<int> v2 { 5, 1, -3 };
+
+  // Form separate tasks for calculating the dot product and magnitudes.
+  pplx::task<int> v1v2Dot([&v1, &v2]() {
+    return calcDotProduct(v1, v2);
+  });
+  pplx::task<double> v1Magnitude([&v1]() {
+    return calcMagnitude(v1);
+  });
+  pplx::task<double> v2Magnitude([&v2]() {
+    return calcMagnitude(v2);
+  });
+
+  std::cout << "Angle between the vectors: "
+            << std::acos((double)v1v2Dot.get() / (v1Magnitude.get() * v2Magnitude.get()))
+            << " radians."
+            << std::endl;
+
+  return 0;
+}
+```

+- remove RabbitMQ for now, remove log4cpp, cpprestsdk
+- use stripped version off pplx (without cpprestsdk)
+
 # 1.6.0
 - change workspace to vscode remote containers
 - install most of dependencies either with apt or vcpkg in the remote container
