+Task Preparation System (TPS)
+================
+
+The Task Preparation System (TPS) is used to prepare tasks (problems) in programming contests.
+It has been developed and first used in the [IOI 2017](http://ioi2017.org/)
+in Tehran, Iran.
+
+
+Installation
+------------
+After cloning the project, just run `install-tps.sh` (or `install-tps.bat` in Windows with MSYS/Cygwin).
+This will add `tps` command to PATH and also add bash completion for it.
+
+
+
+Behavior
+--------
+The `tps` command is a light weight script that locates `BASE_DIR`, the directory containing `problem.json`, and then, runs the corresponding script in the `scripts` directory.
+For example, `tps compile a.cpp` runs `${BASE_DIR}/scritps/compile.sh` with argument `a.cpp`.
+
+The contents of `scripts` directory in `${BASE_DIR}` of a problem are originated from `scripts` directory in TPS repository, but they can be modified/customized for a specific problem.
+Anyway, they can be updated using command `upgrade-scripts.sh`.
+It helps a lot in detecting changes and conflicts.
+
+
+
+Documentation
+-------------
+A detailed documentation is provided in the `doc` directory.
