+When in a Project -> Settings, you will find Features on the bottom of the page that you can toggle.
+Below you will find a more elaborate explanation of each of these.
+
+
+## Issues
+
+Issues is a really powerful, but lightweight issue tracking system.
+You can make tickets, assign them to people, file them under milestones, order them with labels and have discussion in them.
+They integrate deeply into GitLab and are easily referenced from anywhere by using # and the issuenumber.
+At GitLab.com, we use this for all our project management needs.
+
+## Merge Requests
+
+Using a merge request, you can review and discuss code before it is merged in the branch of your code.
+As with issues, it can be assigned; people, issues, etc. can be refereced; milestones attached.
+We see it as an integral part of working together on code and couldn't work without it.
+
+
+## Wiki
+
+This is a separate system for documentation, built right into GitLab.
+It is source controlled and is very convenient if you don't want to keep you documentation in your source code, but you do want to keep it in your GitLab project.
+
+
+## Wall
+
+For simple, project specific conversations, the wall can be used.
+It's very lightweight and simple and works well if you're not interested in using issues, but still want to occasionally communicate within a project.
+
+
+## Snippets
+
+Snippets are little bits of code or text.
+This is a nice place to put code or text that is used semi-regularly within the project, but does not belong in source control.
+For example, a specific config file that is used by > the team that is only valid for the people that work on the code.
