Three steps, then done

01
Create a site

Import markdownd files and assets from github repo or your device. Cirth reads your file structure and sets up sync automatically. Or get started with blank site

02
Write your docs

Write your docs and update them using our editor. You can editor your content in raw markdown format or rich-text mode. Our editor handles both

03
Publish

Point your domain, toggle live. Your docs deploy and you get yourself a pretty and fast doc site.

No surprises. No seat traps.
