 ### Running the application
@@ -105,6 +112,20 @@ This can be made easily from the builder container:
 > Please note that the phraseanet image does not contain nor `composer` neither `node` tools. This allow the final image to be slim.
 > If you need to use dev tools, ensure you are running the `builder` image!
 
+### Developer shell
+
+You can also obtain a shell access in builder container:
+
+```bash
+docker-compose run --rm builder /bin/bash
+# or
+docker-compose run --rm builder /bin/zsh
+```
+
+In this container you will have the same libraries (PHP, Node, composer, ...) that are used to build images.
+Also you have utils for development like telnet, ping, ssh, git, ...
+Your $HOME/.ssh directory is also mounted to builder's home with your ssh agent.

+### Build images with plugins
+
+Plugins can be installed during build if you set the `PHRASEANET_PLUGINS` env var as follows:
+
+```bash
+PHRASEANET_PLUGINS="git@github.com:alchemy-fr/Phraseanet-plugin-webgallery.git"
+
+# You can optionally precise the branch to install
+# If not precised, the main branch will be pulled
+PHRASEANET_PLUGINS="git@github.com:alchemy-fr/Phraseanet-plugin-webgallery.git(custom-branch)"
+
+# Plugins are separated by spaces
+PHRASEANET_PLUGINS="git@github.com:foo/bar.git(branch-1) git@github.com:baz/42.git"
+```
+
+If you install private plugins, make sure you export your SSH private key content in order to allow docker build to access the GIT repository:
+```bash
+export PHRASEANET_SSH_PRIVATE_KEY=$(cat ~/.ssh/id_rsa)
+# or if your private key is protected by a passphrase:
+export PHRASEANET_SSH_PRIVATE_KEY=$(openssl rsa -in ~/.ssh/id_rsa -out /tmp/id_rsa_raw && cat /tmp/id_rsa_raw && rm /tmp/id_rsa_raw)
