Receive tweets from Twitter accounts and lists

You can use the "/add @account" and "/add_twitter_list" commands (they're using nitter.net in the background).

For Twitter accounts, you can follow a specific account using the "/add @accountName" syntax.

For Twitter lists, use the /add_twitter_list command.
For example, to subscribe the bot to this list: https://twitter.com/i/lists/1461248048525414405, type:
/add_twitter_list 1461248048525414405

Twitter friends

The Feed Reader bot can send you a notification when a Twitter user follows a new account.
Use the /add_twitter_friend command to subscribe the bot to a user.

For example, to know when this user: https://twitter.com/FeedReaderBot follows a new account, type:
/add_twitter_friend FeedReaderBot
