 ## Navigation
 
-GitLab layout contains of 2 sections: left sidebar and content. Left sidebar 
-contains static navigation menu no matter what page you visit. It also has GitLab logo 
-and current user profile picture. Content section contains of header and content itself.  
-Header describes what area of GitLab user see right now and what navigation is 
-available to user in this area. Depends on area (project, group, profile setting) 
-header name and navigation will change. For example when user visits one of the 
-project pages the header will contain a project name and navigation for project 
-pages. When visit group page it will contain a group name and navigation related 
-to this group.
+GitLab's layout contains 2 sections: the left sidebar and the content. The left sidebar contains a static navigation menu. 
+This menu will be visible regardless of what page you visit. The left sidebar also contains the GitLab logo

 ### Adding new tab to header navigation
 
-We try to keep amount of tabs in header navigation between 5 and 10 so it fits on 
-a laptop screens and doest not confure user with too many options. Ideally each 
-tab should represent some separate functionality. So everything related to issue 
-tracker should be under 'Issues' tab while everything related to wiki should 
-be under 'Wiki' tab etc.

 ## Mobile screen size 
 
-We want GitLab work on small mobile screens too. Because of size limitations 
-its impossible to fit everything on phone screen. Its ok in this case to hide 
-part of the UI on smaller resolutions in favor of better user experience. 
-However core functionality like browsing file, creating issue, comment, etc should
-be available on all resolutions.
