 ## Docker ##
 
-**Important:** docker images is for local usage. If you want to use Tracim from network device, its necessary to change some lines in Development.ini file and build new image.
+In case you prefer using Docker:
 
-
-* For windows:
-
-Install [docker toolbox](https://docs.docker.com/toolbox/toolbox_install_windows/)
-
-
-* For linux:
-
-You need to install docker on your server first.
-Example on Debian: `sudo apt-get install docker docker-compose`
+You need to install docker on your server first (see [here for debian](https://docs.docker.com/install/linux/docker-ce/debian/) or [here for windows]([docker toolbox](https://docs.docker.com/toolbox/toolbox_install_windows/)))
 
 Make sure `docker.service` is started correctly.
-exemple on Debian: `sudo systemctl status docker`
 
-**If you want to use the latest stable image: **
+    systemctl status docker.service
 
-    sudo docker run -e DATABASE_TYPE=sqlite \
-               -p 80:80 -p 3030:3030 -p 5232:5232 \
-               -v /var/tracim/etc:/etc/tracim -v /var/tracim/var:/var/tracim algoo/tracim
+Then use image like following (adapt volume paths or ports as you want):
 
-**For another case, you can find exemple here:**
+    sudo docker run \
+        -e DATABASE_TYPE=sqlite \
+        -p 80:80 \
+        -p 3030:3030 \
+        -p 5232:5232 \
+        -v /var/tracim/etc:/etc/tracim \
+        -v /var/tracim/var:/var/tracim \
+        algoo/tracim  # docker image: tracim:unstable for development version, tracim_test:latest for nightly builds
 
-* You can use `algoo/tracim:<$tag>` stable image (replace `<$tag>` by the tag you want to use):
 
-        sudo docker run -e DATABASE_TYPE=sqlite \
-               -p 80:80 -p 3030:3030 -p 5232:5232 \
-               -v /var/tracim/etc:/etc/tracim -v /var/tracim/var:/var/tracim algoo/tracim:<$tag>
