 With this Glitch starter project, you can create a bot that anyone [in the fediverse](https://en.wikipedia.org/wiki/Fediverse) can follow. This project is still in early development with more features coming.
 
-To automate your bot, set up a free service like [cron-job.org](https://cron-job.org/en/), [Uptime Robot](https://uptimerobot.com/), or [a similar one](https://www.google.com/search?q=free+web+cron) to wake up your bot [every 25+ minutes](https://support.glitch.com/t/a-simple-twitter-bot-template/747/16). Use `https://YOUR_PROJECT_NAME.glitch.me/BOT_ENDPOINT` as a URL to which to send the HTTP request.
