 If you're in doubt feel free to start a discussion [here](https://github.com/python-validators/validators/discussions). Thanks for taking interest in this library.
+
+## Documentation
+
+> Documentation is extracted from the source code. Please follow [Google's Python Doc Style](https://google.github.io/styleguide/pyguide.html).
+
+If you're adding/removing a module, you must update the `nav` key in `mkdocs.yml`.
+Then export documentation as follows:
+
+```sh
+$ . ./.venv/bin/activate
+# generate documentation
+$ python package/export TYPE # where TYPE is any of `doc`, `man` or `web`.
+
+# doc - generates docs found here: https://yozachar.github.io/pyvalidators
+# man - generates sphinx based manpages
+# web - generates sphinx based web docs
+```
+
+You can preview the generated documentation:
+
+```sh
+$ . ./.venv/bin/activate
+# To preview mkdocs
+$ mkdocs serve
+# To preview man pages
+$ man docs/_build/man/validators.1
+# To preview sphinx webpages
+$ python -m http.server -d docs/_build/web
+```
+
+## Versioning, Packaging & Releasing (for collaborators)
+
+> You must be familiar with [semantic versioning](https://semver.org) and [Python packaging](https://packaging.python.org).
+
+1. Take a look at the [`CHANGES.md`](CHANGES.md). They are generated with [GitHub's releaser](https://github.com/python-validators/validators/releases/new), and then modified.
+2. Update the changelog. Version number must be updated in both [`SECURITY.md`](SECURITY.md) and [`src/validators/__init__.py`](src/validators/__init__.py).
+3. The final merge commit on the upstream (ie. this repo) is tagged.
+
+    ```sh
+    # syncing with upstream
+    $ git pull upstream master
+    $ git push
+    # tagging that final merge commit before release
+    $ GIT_COMMITTER_DATE=$(git log -n1 --pretty=%aD) git tag -a -m "vMAJOR.MINOR.PATCH" vMAJOR.MINOR.PATCH
+    # pushing tag to remote
+    $ git push --tag
+    $ git push upstream --tag
+    ```
+
+4. To update versioned docs, you must track the `gh-pages` onto a local branch. `git checkout --track upstream/gh-pages`, once.
+5. Checkout to the tag you want to include in the versioned documentation `git checkout TAG_NAME`.
+6. Then using [`mike`](https://github.com/jimporter/mike) (which is already a dev dependency) run `mike deploy -p -u VERSION stable`.
+7. Or use `mike deploy -p -u dev master`, which will deploy docs in the CURRENT commit as the `latest` documentation.
+8. Run `./package/roll.sh` (or `./package/roll.ps1`) to generate both sdist and bdist.
+9. Install [`twine`](https://pypi.org/project/twine) using [`pipx`](https://pipx.pypa.io) to upload package to PyPI.
+
+    ```sh
+    # publishing
+    $ twine check dist/*
+    $ twine upload dist/*
+    ```
+
+10. Create a GitHub release with the contents from the [changelog](CHANGES.md). Upload the wheel from `dist/` along with the shasum file generated with:
+
+    ```sh
+    # generate sha256sum
+    $ sha256sum dist/validators-VERSION-py3-none-any.whl > dist/validators-VERSION-py3-none-any.whl.sha256
+    ```
