+# ircsuite
+
+Like tootsuite but for IRC.
+
+This basically connects to Mastodon and then relays public, home, and optionally hashtag searches to your IRC client, bot or script can react to toots in real time.
+
+## TODO
+
+- [ ] Hashtag streaming by joining `#hashtag`
+- [ ] Multiple mastodon account support
+      `#/<accname>/<hashtag>` ?
+- [ ] Multiple user support
+- [ ] Full text searches by joining `?terms+in+query+syntax`
+      Common paginated contextual UI concepts that people have been talking about for chatbots might be amazing here, as that is what this would basically be.
+- [ ]
