 **Note:** During this installation some files will need to be edited manually. If you are familiar with vim set it as default editor with the commands below. If you are not familiar with vim please skip this and keep using the default editor.
 
-    # Install vim and set as default editor
-    sudo apt-get install -y vim
-    sudo update-alternatives --set editor /usr/bin/vim.basic

 Ubuntu 14.04 (Trusty Tahr) doesn't have the `libre2-dev` package available, but
 you can [install re2 manually](https://github.com/google/re2/wiki/Install).
 
 If you want to use Kerberos for user authentication, then install libkrb5-dev:
 
-    sudo apt-get install libkrb5-dev
+```sh
+sudo apt-get install libkrb5-dev
+```
 
 **Note:** If you don't know what Kerberos is, you can assume you don't need it.

-    # Install Git
-    sudo apt-get install -y git-core

 **Note:** You can set the Administrator/root password and e-mail by supplying them in environmental variables, `GITLAB_ROOT_PASSWORD` and `GITLAB_ROOT_EMAIL` respectively, as seen below. If you don't set the password (and it is set to the default one) please wait with exposing GitLab to the public internet until the installation is done and you've logged into the server the first time. During the first login you'll be forced to change the default password.

 If you'd like to connect to a Redis server on a non-standard port or on a different host, you can configure its connection string via the `config/resque.yml` file.
 
-    # example
-    production:
+```
+# example
+production:
   url: redis://redis.example.tld:6379
+```
 
 If you want to connect the Redis server via socket, then use the "unix:" URL scheme and the path to the Redis socket file in the `config/resque.yml` file.
 
-    # example
-    production:
+```
+# example
+production:
   url: unix:/path/to/redis/socket

 Also you can use environment variables in the `config/resque.yml` file:

-    production:
+```
+# example
+production:
   url: <%= ENV.fetch('GITLAB_REDIS_URL') %>

 ### Custom SSH Connection
 
 If you are running SSH on a non-standard port, you must change the GitLab user's SSH config.
 
-    # Add to /home/git/.ssh/config
-    host localhost          # Give your setup a name (here: override localhost)
+```
+# Add to /home/git/.ssh/config

     port 2222           # Your port number
     hostname 127.0.0.1; # Your server name or IP
+```
 
 You also need to change the corresponding options (e.g. `ssh_user`, `ssh_host`, `admin_uri`) in the `config\gitlab.yml` file.
