+# Docker Compose
+
+## Installation
+Install a recent version of [Docker](https://docs.docker.com/get-docker/), and [Docker Compose](https://docs.docker.com/compose/install/).
+
+For Ubuntu 18/20 systems this is:
+
+```bash
+curl -fsSL https://get.docker.com -o get-docker.sh
+sudo sh get-docker.sh
+sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
+sudo chmod +x /usr/local/bin/docker-compose
+```
+
+Then run as root
+
+```bash
+git clone https://github.com/mediacms-io/mediacms
+cd mediacms
+```
+
+The default option is to serve MediaCMS on all ips available of the server (including localhost).
+If you want to explore more options (including setup of https with letsencrypt certificate) checkout the docs on the [Docker deployment](/docs/Docker_deployment.md) page for different docker-compose setups to use.
+
+Run
+
+```bash
+docker-compose up
+```
+
+This will download all MediaCMS related Docker images and start all containers. Once it finishes, MediaCMS will be installed and available on http://localhost or http://ip
+
+
+## Configuration
+Checkout the configuration docs on [Configuration](docs/Configuration.md) page.
