This serves two purpose: Secure access to your website's Static CMS and allows it to read and update content files in your repo. More information about configuring the backend can be found [here](/docs/backends-overview/).
For starters, you can get by with a basic configuration that includes required information like Git provider, branch and folders to save files to.
Once you've gotten the hang of it, you can use the file to build whatever collections and content modeling you want. Check out the [this section](/docs/configuration-options/#configuration-file) for full details about all available configuration options.
To learn how to query raw content managed by Static CMS and reformat them for delivery to end users, please refer the dedicated section for your site generator in the Table of Content.
If you are experimenting with Static CMS or testing things out, you can connect it to a local Git repository instead of a live one. Learn how to do it [here](/docs/beta-features/#working-with-a-local-git-repository).
