• the bot looks for config.edn at its relative path by default, an alternative location can be specified either using the MASTODON_BOT_CONFIG environment variable or passing the path to config as an argument

• transformations have source (s/def ::source-type #{:twitter :rss :tumblr}) und target (s/def ::target-type #{:mastodon}) you can combine freely. Multiple transformations for same source-target combination are possible. Source and targets refer to the auth section for their credentials.

• install NPM modules: npm install

• compile: npx shadow-cljs release app

• run the bot: npm start

• to poll at intervals setup a cron job such as:

  */30 * * * * npm start /path/to/config.edn > /dev/null 2>&1
