# How to add a file You can create a file in your [shell](command-line-commands.md) or in GitLab. To create a file in GitLab, sign in to GitLab. Select a project on the right side of your screen: ![Select a project](img/select_project.png) It's a good idea to [create a branch](create-branch.md), but it's not necessary. Go to the directory where you'd like to add the file and click on the "+" sign next to the name of the project and directory: ![Create a file](img/create_file.png) Name your file (you can't add spaces, so you can use hyphens or underscores). Don't forget to include the markup language you'd like to use : ![File name](img/file_name.png) Add all the information that you'd like to include in your file: ![Add information](img/white_space.png) Add a commit message based on what you just added and then click on "commit changes": ![Commit changes](img/commit_changes.png)
