 `timeout_mins` controls how long the mypy daemon will time out after,

+## Annotating files from mypy error logs
+I kept running into cases a lot where CI systems generate mypy error logs, and
+I needed to fix those errors with my local copy. If you copy all the mypy
+errors into a file, say `error.txt`, you can have idlemypyextension annotate
+all of those files with a command like this:
+
+```bash
+idlemypyextension error.txt
+```
+
+which will open a blank IDLE window, hook into `idlemypyextension`, have it
+add annotations to all files referenced in error log file, and then close
+that temporary blank window, leaving all the files with errors still open.
