 ## Installation
 
+This shows how to install Jirafeau by your own, it's quite simple but you can
+also use a [docker image](https://hub.docker.com/r/mojo42/jirafeau/) or build
+it yourself. Check [docker folder](docker/README.md) for more informations.

 System requirements:

+# Jirafeau in Docker
+
+Jirafeau is a small PHP application so running it inside a docker is pretty straightforward.
+
+## Get Jirafeau's docker image
+
+### Pull docker image from Docker Hub
+
+`docker pull mojo42/jirafeau`
+
+### Build your own docker image
+
+```
+git clone https://gitlab.com/mojo42/Jirafeau.git
+cd Jirafeau
+docker build -t mojo42/jirafeau:latest .
+```
+
+## Run Jirafeau image
+
+Once you have your Jirafeau's image, you can run a quick & dirty Jirafeau using:
+```
+docker run -d -p 8000:80 mojo42/jirafeau
+```
+and then connect on [locahost:8000](http://localhost:8000) and proceed to installation.
+
+An other way to run Jirafeau (in a more controlled way) is to mount your Jirafeau's reprository in /www folder so your data are outside the container. This way, you will be able to easily make backups, upgrade Jirafeau, change configuration and develop Jirafeau.
+```
+docker run -d -p 8000:80 -v$(pwd):/www mojo42/jirafeau
+```
+
+There are also other ways to manage your container (like docker's volumes) but this is out of the scope of this documentation.
+
+## Few notes
+
+- SSL is currently not enabled in docker's image for the moment
+- `var-...` folder where lives all uploaded data is protected from direct access
+- Image has been made using [Alpine Linux](https://alpinelinux.org/) with [lighttpd](https://www.lighttpd.net/) which makes the container very light and start very quickly
