+# Workflows
+
+To automate running the [scripts](./scripts.md), we use [GitHub Actions workflows](https://docs.github.com/en/actions/using-workflows).
+
+Each workflow includes its own set of scripts that can be run either manually or in response to a repository event.
+
+## check
+
+Sequentially runs the `api:load`, `playlist:lint`, and `playlist:validate` scripts whenever a new pull request is opened, blocking the merge if it detects any errors.
+
+## format
+
+Sequentially runs the `api:load`, `playlist:format`, `playlist:lint`, and `playlist:validate` scripts.
+
+## update
+
+Runs every day at 0:00 UTC. It sequentially executes the `api:load`, `playlist:update`, `playlist:lint`, `playlist:validate`, `playlist:generate`, `playlist:export`, and `readme:update` scripts, then automatically deploys the updated files if successful.
+
+## validate_issue
+
+Runs when an issue is opened or edited. It checks the requests for errors using `issue:validate` script and, if any are found, the bot posts them in the comments.
+
+## validate_label
+
+Triggers when a new label is added to an issue. It checks the label, and if it's incorrect, the bot deletes it and leaves a comment explaining why.
