+===================================
+1. Fork and clone the repository::
+
+    $ git clone git@github.com:tarasko/picows.git
+    $ cd picows
+
+2. Create a virtual environment and activate it::
+
+    $ python3 -m venv picows-dev
+    $ source picows-dev/bin/activate
+
+
+3. Install development dependencies::
+
+    # To run tests
+    $ pip install -r requirements-test.txt
+
+    # To run benchmark
+    $ pip install -r requirements-benchmark.txt
+
+    # To build docs
+    $ pip install -r docs/requirements.txt
+
+4. Build inplace and run tests::
+
+    $ export PICOWS_BUILD_EXAMPLES=1
+    $ python setup.py build_ext --inplace
+    $ pytest -s -v
+
+    # Run specific test
+    $ pytest -s -v -k test_client_handshake_timeout[uvloop-plain]
+
+5. Run benchmark::
+
+    $ python -m examples.echo_server
+    $ python -m examples.echo_client
+
+6. Build docs::
