+# Try Out Development Containers: PHP
 
-# Contributing
+This is a sample project to go along with the "Try a dev container" quick start for the **[VS Code Remote - Containers](https://aka.ms/vscode-remote/containers)** extension.
+
+**If you are not yet in a development container, [see below](#setting-up-the-development-container).**
+
+## Things to try
+
+Once you have this sample opened in a container, you'll be able to work with it like you would locally.
+
+Some things to try:
+
+1. **Edit:**
+   - Open `index.php`
+   - Try adding some code and check out the language features.
+1. **Terminal:** Press <kbd>ctrl</kbd>+<kbd>shift</kbd>+<kbd>\`</kbd> and type `uname` and other Linux commands from the terminal window.
+1. **Build, Run, and Debug:**
+   - Open `index.php`
+   - Add a breakpoint (e.g. on line 4).
+   - Press <kbd>F5</kbd> to launch the app in the container.
+   - Once the breakpoint is hit, try hovering over variables, examining locals, and more.
+1. **Running a server:**
+   - From the terminal, run `php -S localhost:8000`
+   - Press <kbd>F1</kbd> and run the **Remote-Containers: Forward Port from Container...** command.
+   - Select port `8000`.
+   - Click "Open Browser" in the notification that appears to access the web app on this new port.
+   - Look back at the terminal, and you should see the output from your site navigations
+   - Edit the text on line 16 in `index.php` and refresh the page to see the changes immediately take affect
+
