+1. Fork the repository by clicking on the ``Fork`` button on the repository's page. This creates a copy of the code under your GitHub user account.
+
+2. Clone your fork to your local disk, and add the base repository as a remote.
+```bash
+$ git clone [email protected]:<your-GitHub-username>/chef-transformer.git
+$ cd chef-transformer
+$ git remote add upstream https://github.com/chef-transformer/chef-transformer.git
+```
+
+3. Create a new branch to hold your development changes.
+```bash
+$ git checkout -b a-descriptive-name-for-your-changes
+```
+
+> NOTE: Do not work on the ``main`` branch.
+
+4. Set up a development environment by running the following command in a virtual environment.
+```bash
+$ pip install -r requirements.txt
+```
+
+5. DEVELOP THE CODE
+
+6. It is a good idea to sync your copy of the code with the original repository regularly. This way you can quickly account for changes.
+```bash
+$ git fetch upstream
+$ git rebase upstream/main
+```
+
+7. Push the changes to your account using:
+```bash
+$ git push -u origin a-descriptive-name-for-your-changes
+```
+
+8. Once you are satisfied (and the checklist above is happy too), go to the webpage of your fork on GitHub. Click on ``Pull Request`` to send your changes to the project maintainers for review.
