# Tutorial Library

> Video and written tutorials from the Cognition team on using Devin across the IDE, DeepWiki, Ask Devin, Slack, and everyday development workflows.

Devin is the biggest single contributor to the Cognition repositories. Whether it's delegating frontend tasks, fixing bugs, or building internal tools, Devin works in all the tools where we collaborate with the rest of the team. Here are some examples of good ways to work with Devin:

* Tag Devin on a [Slack](/integrations/slack) or [Teams](/integrations/microsoft-teams) thread about a bug you're discussing with coworkers
* Hand off a small refactor or cleanup you spot while coding instead of adding it to your backlog, and keep working on your main task while Devin opens a PR
* Set up an [automation](/product-guides/automations) so Devin handles recurring work on its own, like triaging new bug reports or fixing failing CI checks
* Kick off multiple sessions with the long tail of your todo list at the beginning of the day and return to draft PRs waiting for review around lunch
* Tag Devin on feature requests or issues raised by customers in your shared Slack or Teams channels
