+# ModOrganizer2 - Python Proxy
+
+This repository contains the Python proxy plugin for ModOrganizer2.
+The proxy plugin allow developers to write Python plugins for ModOrganizer2.
+
+## Setup, build, tests
+
+This repository is part of MO2 main repositories and should usually be build using
+[`mob`](https://github.com/ModOrganizer2/mob).
+
+## Organization
+
+This repositories contains 5 sub-projects in `src`.
+The interface between Python and C++ is done using the
+[`pybind11`](https://github.com/pybind/pybind11) library.
+
+- [`src/proxy`](src/proxy/) contains the actual proxy plugin. This project is a simple
+  interface between MO2 and the runner (see below).
+  - This project generates the `plugin_python.dll` library.
+  - TODO: this project generates the translation file (-> moved the file).
+  - TODO: this project install necessary files for the plugin (Python DLL, Python
+    libraries, etc), INCLUDING `mobase`.
+- [`src/runner`](src/runner/) contains the Python runner. This is the project that
+  instantiates a Python interpreter and load/unload Python plugins.
+  - TODO: static library
+- [`src/pybind11-qt](src/pybind11-qt/) contains many utility stuff to interface
+  pybind11 with Qt and PyQt.
+- [`src/pybind11-utils`](src/pybind11-utils/) contains some utility stuff pybind11.
+  This project is header-only.
+- [`src/mobase](src/mobase) contains the Python plugin interface.
+  - This projects generates the `mobase` Python library.
+
+Some (woefully incomplete) tests are available under `tests`, split in three
+sub-directories:
+
+- [`tests/mocks`](tests/mocks/) simply contains mocks of `uibase` interfaces to be used
+  in the two other test projects.
+- [`tests/python`](tests/python/) contains Python tests for `pytest`.
+  This project generates a bunch of Python test libraries that are then imported in
+  Python test files (`test_*.py`) and tested using `pytest`.
+  These tests mostly cover the pybind11 Qt and utility stuff, and some standalone
+  MO2 classes and functions (`IFileTree`, `GuessedString`, etc).
+- [`tests/runner`](tests/runner/) contains C++ tests, using GTest
+  Tests in this project instantiate a Python runner and then use it to check that
+  plugins implemented in Python can be used properly on the C++ side.
