-# GitLab basics guides **(FREE)**
+This document was moved to [another location](../user/index.md).
 
-This section provides resources to help you start working with GitLab and Git by focusing
-on the basic features that you must use.
-
-This documentation is split into the following groups:
-
-- [GitLab-specific functionality](#gitlab-basics), for basic GitLab features.
-- [General Git functionality](#working-with-git-from-the-command-line), for working
-  with Git in conjunction with GitLab.
-
-## GitLab basics
-
-The following are guides to basic GitLab functionality:
-
-- [Create and add your SSH public key](../user/ssh.md), for enabling Git over SSH.
-- [Create a project](../user/project/working_with_projects.md#create-a-project), to start using GitLab.
-- [Create a group](../user/group/index.md#create-a-group), to combine and administer
-  projects together.
-- [Create a branch](create-branch.md), to make changes to files stored in a project's repository.
-- [Feature branch workflow](feature_branch_workflow.md).
-- [Fork a project](../user/project/repository/forking_workflow.md#creating-a-fork), to duplicate projects so they can be worked on in parallel.
-- [Add a file](add-file.md), to add new files to a project's repository.
-- [Create an issue](../user/project/issues/managing_issues.md#create-an-issue),
-  to start collaborating within a project.
-- [Create a merge request](../user/project/merge_requests/creating_merge_requests.md), to request changes made in a branch
-  be merged into a project's repository.
-- See how these features come together in the [GitLab Flow introduction video](https://youtu.be/InKNIvky2KE)
-  and [GitLab Flow page](../topics/gitlab_flow.md).
-
-## Working with Git from the command line
-
-If you're familiar with Git on the command line, you can interact with your GitLab
-projects just as you would with any other Git repository.
-
-These resources can help you get further acclimated to working on the command line.
-
-- [Start using Git on the command line](start-using-git.md), for some simple Git commands.
-- [Command line basics](command-line-commands.md), to create and edit files using the command line.
-
-More Git resources are available in the GitLab [Git documentation](../topics/git/index.md).
