Why connect GitHub
If your site's code lives in GitHub, every small change used to mean waiting for a developer or learning enough to do it yourself. A new FAQ block, a price that changed, a broken link a customer spotted. None of it is hard, but all of it stalls.
With the repository connected, Crevio works in your code directly. You say what you want in plain language and it makes the edit, commits it under the Crevio bot name, and opens a pull request that explains the change. Because Crevio also knows your store, it can pull real product names, prices, and descriptions into the page instead of placeholders.
Working with a developer
Crevio fits into a normal GitHub routine. Changes arrive as pull requests, so a developer or you can review them before anything is merged. It can open issues, read the results of your GitHub Actions runs and checks, and explain a failing build in words a non-developer can follow. If your store's deployment fails, a task can pick that up, dig into the error, and open an issue with a proposed fix.
Limits worth knowing
GitHub events don't start Crevio tasks. A new issue or a merged pull request won't trigger anything on their own, so use a schedule or a store event instead. Crevio can only create brand-new repositories inside a GitHub organization. And it works in the repo your site lives in, not across every project on your account, so your other code stays untouched.
