+# GitHub
+### How to use:
+- Copy the [entire script](https://github.com/k3rielit/scripts/raw/main/github/lists.js)
+- Go to any [GitHub](https://github.com) page
+- Paste it into the console
+- Change the `uid` (first line) to a GitHub account name
+- Press `Enter`
+### How to search if a list includes an item ([idea](https://github.com/orgs/community/discussions/28515))
+- Run the script as written above
+- Run the `isItemOnList(item, list)` command in the console
+  - Case sensitive, expects the list's id (for ex. `asd-asd`, not `asD/* ASD`)
+  - `item` works with the URL and the title too
+- If it's on the list, it returns `true`, otherwise `false`
