-ESLint GitHub bot
-==========================
+# ESLint GitHub bot
 
 `eslint-github-bot` is a bot created with [probot](https://github.com/probot/probot) which automates some common tasks for repositories run by the ESLint team.
 
-The bot can perform the following tasks:
-
-* **Triage** - adds the "triage" label to newly-created issues which don't have labels.
-* **Commit message check** - adds a status check to pull requests to verify that they follow ESLint's [pull request guidelines](https://eslint.org/docs/developer-guide/contributing/pull-requests#step-2-make-your-changes)
-* **Needs info** - adds a comment to issues requesting more information when a maintainer adds the `needs info` label.
-* **Release/TSC meeting issues** - creates a new issue with the `release`/`tsc meeting` label scheduled two weeks later, after another release/TSC meeting issue is closed.
-* **Release monitor** - searches the repository for an issue with the `release` and `patch release pending` labels, indicating that a patch release might soon be created from `master`. If an issue is found, adds a pending status check to all PRs that would require a semver-minor release, to prevent anyone from accidentally merging them.
-* **Issue Archiver** - Locks and adds a label to issues which have been closed for a while
-* **Issue Closer** - Closes and adds a label to issues which have been inactive for a while
-* **WIP Tracking** - adds pending status check for PRs with WIP in the title or with "do not merge" label, and marks the status check as successful once the WIP indicators are removed.
-* **PR ready to merge** (experimental) - adds a label to all PRs which are "ready to merge", defined by the following criteria:
-    * At least one review is approved.
-    * Build status is `success`.
-* **Check unit tests** (experimental) - makes sure a PR contains unit tests. This check will be ignored for PRs with `Build|Chore|Docs|Upgrade` in the commit message.
-* **Duplicate comments** (inactive) - removes all the duplicates comments by this bot and leaves the last one of each type.
