+GitLab requires at least Redis 2.8. The following guide is for Debian 7 and
+Ubuntu 12.04. If you are using Debian 8 or Ubuntu 14.04 and up, follow the
+[installation guide](installation.md).
+
+## Install Redis 2.8 in Debian 7
+
+Redis 2.8 is included in the Debian Wheezy [backports] repository.
+
+1. Edit `/etc/apt/sources.list` and add the following line:
+
+    ```
+    deb http://http.debian.net/debian wheezy-backports main
+    ```
+
+1. Update the repositories:
+
+    ```
+    sudo apt-get update
+    ```
+
+1. Install `redis-server`:
+
+    ```
+    sudo apt-get -t wheezy-backports install redis-server
+    ```
+
+1. Follow the rest of the [installation guide](installation.md).
+
+## Install Redis 2.8 in Ubuntu 12.04
+
+We will [use a PPA](https://launchpad.net/~chris-lea/+archive/ubuntu/redis-server)
+to install a recent version of Redis.
+
+1. Install the PPA repository:
+
+    ```
+    sudo add-apt-repository ppa:chris-lea/redis-server
+    ```
+
+    Your system will now fetch the PPA's key. This enables your Ubuntu system to

 # Web hooks
 
+_**Note:**
+Starting from GitLab 8.5:_
+
+- _the `repository` key is deprecated in favor of the `project` key_
+- _the `project.ssh_url` key is deprecated in favor of the `project.git_ssh_url` key_
+- _the `project.http_url` key is deprecated in favor of the `project.git_http_url` key_

 Project web hooks allow you to trigger an URL if new code is pushed or a new issue is created.
 
 You can configure web hooks to listen for specific events like pushes, issues or merge requests. GitLab will send a POST request with data to the web hook URL.
