How to fill in secret values

Twitter

Create a new Twitter app and add the following callback urls:

http://localhost:3000/api/auth/callback
https://mute-vc.now.sh/api/auth/callback
https://mute-vc.vercel.app/api/auth/callback
https://mute.vc/api/auth/callback

Add your consumer API key to TWITTER_KEY and API secret key to TWITTER_SECRET. Turn on Read and write permissions.

Finally, create a new Twitter list and fill out TWITTER_LIST_OWNER and TWITTER_LIST_SLUG (twitter.com/:username/lists/:slug).
