-## Install
+## Installation
+
+MediaCMS can be installed through an automated script that installs and configures all needed services on a single server, and through Docker Compose.
+
+### Docker Compose installation
+With a recent version of Docker Compose installed, run as root
+
+
+```bash
+git clone https://github.com/mediacms-io/mediacms
+cd mediacms
+docker-compose build && docker-compose up
+```
+
+This will build an image, download and setup necessary images and start all containers. Once it finishes, MediaCMS will be installed on http://localhost
+
+For more instructions, checkout the docs on the [Docker deployment](docs/Docker_deployment.md) page. Docker Compose support has been contributed by @swiftugandan.
