+# Droplet configuration
+
+It's a sample production configuration to deploy the Index on a Digital Ocean droplet.
+
+Please, refer to each project's README for more information about how to run them using docker.
+
+## Requirements
+
+- Docker version 24.0.7, build afdd53b.
+- Docker Compose version v2.3.3.
+- GNU bash, version 5.2.15(1)-release (x86_64-pc-linux-gnu).
+
+## Install
+
+```s
+mkdir ~/Tmp && cd ~/Tmp
+git clone [email protected]:torrust/torrust-compose.git
+cd torrust-compose/droplet
+./bin/install.sh
+```
+
+## Usage
+
+To start the application:
+
+```s
+./bin/start.sh
+```
+
+To stop the application:
+
+```s
+./bin/stop.sh
+```
+
+By default, the application will:
+
+- Be available at <http://localhost:3000>.
+- Use the `./storage/database` directory to store the data.
+- Use SQLite as the database engine.
+
+After starting the application you should see these running containers:
+
+```s
+$ docker ps
