+Thank you for considering improving piptools-sync, any contribution is much welcome!
+
+# Requesting a new feature
+
+If you would like to suggest a new feature, you can create a [feature request](https://github.com/Stephen-RA-King/piptools-sync/issues/new?&template=feature_request.md).
+
+# Reporting a bug
+
+If you encountered an unexpected behavior, please [open a new issue](https://github.com/Stephen-RA-King/piptools-sync/issues/new)
+and describe the problem you have found.
+
+An ideal bug report includes:
+
+-   The Python version you are using
+-   The piptools-sync version you are using (you can find it with `piptools-sync --version`)
+-   Your operating system name and version (Linux, MacOS, Windows)
+-   Your development environment and local setup (IDE, Terminal, project context, any relevant information that could be useful)
+-   Some [minimal reproducible example](https://stackoverflow.com/help/mcve)
+
+# Implementing changes
+
+If you want to enhance piptools-sync by implementing a changes, please [open a new issue](https://github.com/Stephen-RA-King/piptools-sync/issues/new) first.
+
+Then, implement the following workflow:
+
+1.  Fork the [piptools-sync](https://github.com/Stephen-RA-King/piptools-sync) project from GitHub.
+
+2.  Create a virtual environment with your favourite tool (virtualenv with virtualenv wrapper, venv etc)
+    using one of the supported versions of Python: ![](https://img.shields.io/pypi/pyversions/piptools-sync).
+
+3.  Activate your virtual environment.
+
+4.  Clone the repository locally:
+
+        $ git clone [email protected]:your_name_here/piptools-sync.git
+        $ cd piptools-sync
+
+5.  Install piptools-sync in development mode:
+
+        $ pip install -e .
+
+6.  Install pre-commit hooks that will check your commits:
+
+        $ pre-commit install --install-hooks
+
+7.  Create a new branch from `main`:
+
+        $ git checkout main
+        $ git branch fix_bug
+        $ git checkout fix_bug
+
+8.  Implement the modifications. During the process of development, honor [PEP 8](https://www.python.org/dev/peps/pep-0008/) as much as possible.
+
+9.  Add unit tests and ensure all are passing:
+
+        $ tox
+
+10. Update the documentation.
+
+11. If your development modifies piptools-sync behavior, update the `CHANGELOG.md` file with your changes.
+
+12. `add` and `commit` your changes, then `push` your local project:
+
+        $ git add .
+        $ git commit -m 'Add succinct explanation of what changed'
+        $ git push origin fix_bug
+
+13. If previous step failed due to the pre-commit hooks, fix reported errors and try again.
+
+14. Finally, [open a pull request](https://github.com/Stephen-RA-King/piptools-sync/compare) before getting it merged!
