+- [Coding Style](#coding-style)
+  - [Solidity](#solidity)

+
+## Coding Style
+
+### Solidity
+
+* Solidity portions of the codebase adhere follow the official [Solidity Styleguide]
+
+### JavaScript
+
+### Python
+
+* Python portions of the codebase follow standard PEP8 best practices.
+* Python code must be formatted using the Black formatter using the provided settings.
+
+## Documentation
+
+New addition to the codebase must be fully documented.
+
+- JavaScript portions of the code should be annotated using JSDoc style docstrings.
+- Solidity portions of the code should be fully annotated using [NatSpec] and [Solidity Domain for Sphinx].
+
+Documentation is generated using [solidity-docgen] and rendered via [mkdocs].
+[solidity-docgen] parses NatSpec and outputs `.md` files inside `docs/md-build` according
+to an Handlebars template located at `docs/solidity-docgen-templates/contract.hbs`.
+
+**NOTE:** Each `.sol` file should contain only one `Interface` or `Contract`.
+
+To build the documentation:
+
+```console
+yarn build docs
+```
+
+To serve the documentation
+
+```console
+yarn build docs:serve
+```
+
+### mkdocs
+
+To install [mkdocs] Python must be installed in the system.
+
+```
+pip install docs/requirements.in
+```
+
+**NOTE:** Working inside a virtual environment is highly recommended!
