-    # Install first
+## Installation

+## Site Configuration
+
+Download an example site config:
+
     sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab -P /etc/nginx/sites-available/
     sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab

     # to the IP address and fully-qualified domain name
-    # of the host serving GitLab.
+    # of your host serving GitLab

-    # Restart nginx:
+## Restart
+
     sudo /etc/init.d/nginx restart
 
 
-# Done!  Visit YOUR_SERVER for gitlab instance
+# Done!
 
-You can login via web using admin generated with setup:
+Visit YOUR_SERVER for your first GitLab login.
+The setup has created an admin account for you. You can use it to log in:
 
     admin@local.host
     5iveL!fe
 
+**Important Note**
+Please go over to your profile page and immediately chage the password, so
+nobody can access your GitLab by using this login information later on.
+
+**Enjoy!**
