I'm not sure if there is a guide or not, but you can follow these steps.

1. Restart your Mac while holding down Command R.

2. Press Command F 5 to turn Voiceover on.

3. Select Disk Utility from the application selection table.

4. In Disk Utility, select your startup disk, usually called Macintosh HD, and click the erase button in the toolbar.

5. When the erase and reformat is finished, quit Disk Utility and select Install macOS from the table. Follow the normal prompts to install macOS on your freshly formatted startup volume.

Do I have to backup first, or put my files in a usv or somethimg so that they don't get erased?
