+# PHP Web Application Example - Voice Notes
+
+## Requirements
+
+1. Docker
+2. Rev AI access token, available at [https://rev.ai/auth/signup](https://rev.ai/auth/signup).
+3. ngrok (only required when running locally or without a public webhook URL)
+4. ngrok authentication token available at [https://dashboard.ngrok.com/signup](https://dashboard.ngrok.com/signup)
+
+## Setup
+
+1. Clone this repository. Change to the `php_examples/voicenotes` working directory.
+2. Rename the `.env.sample` file to `.env`.
+3. In the `.env` file, add the Rev AI access token as the value for the environment variable `REVAI_ACCESS_TOKEN`.
+4. In the `.env` file, add the callback URL as the value for the environment variable `CALLBACK_PREFIX`. If you are working locally, configure an ngrok tunnel (`ngrok http 80`) and use the ngrok callback URL.
+
+5. Start the containers, building them if necessary:
+
+    ```
+    docker-compose up -d --build
+    ```
+
+6. Install Composer packages, deleting any older ones that may exist:
+
+    ```
+    docker exec voicenotes_app rm -rf vendor/
+    docker exec voicenotes_app composer install
+    ```
+
+7. Browse to `http://YOURDOCKERHOST/index` to use the application.
