+## Pull Requests
+
+Pull requests are a great way to add new content to PHP The Right Way, as well
+as updating any browser issues or other style changes. Pretty much any sort of
+change is accepted if seen as constructive.
+
+Adhering to the following process is the best way to get your work
+included in the project:
+
+1. [Fork](https://docs.github.com/en/get-started/quickstart/fork-a-repo) the
+   project, clone your fork, and configure the remotes:
+
+   ```bash
+   # Clone your fork of the repo into the current directory
+   git clone https://github.com/<your-username>/php-the-right-way.git
+   # Navigate to the newly cloned directory
+   cd php-the-right-way
+   # Assign the original repo to a remote called "upstream"
+   git remote add upstream https://github.com/codeguy/php-the-right-way.git
+   ```
+
+2. If you cloned a while ago, get the latest changes from upstream:
+
+   ```bash
+   git checkout gh-pages
+   git pull upstream gh-pages
+   ```
+
+3. Create a new topic branch (off the main project development branch) to
+   contain your change or fix:
+
+   ```bash
+   git checkout -b <topic-branch-name>
+   ```
+
+4. Install the [Jekyll](https://github.com/jekyll/jekyll/) gem and dependencies to preview locally:
+
+    ```bash
+    # Install the needed gems through Bundler
+    bundle install --path vendor/bundle
+    # Run the local server
+    bundle exec jekyll serve
+    ```
+
+5. Commit your changes in logical chunks. Please adhere to these [git commit
+   message guidelines](https://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html)
+   or your content is unlikely be merged into the main project. Use Git's
+   [interactive rebase](https://docs.github.com/en/get-started/using-git/about-git-rebase)
+   feature to tidy up your commits before making them public.
+
+6. Locally merge (or rebase) the upstream development branch into your topic branch:
+
+   ```bash
+   git pull [--rebase] upstream gh-pages
+   ```
+
+7. Push your topic branch up to your fork:
+
+   ```bash
+   git push origin <topic-branch-name>
+   ```
+
+8. [Open a Pull Request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/about-pull-requests)
+    with a clear title and description.
