+## How it Works
+
+- Mastodot
+  - connects to the mastodon streaming api
+  - saves all received toot objects as json files in the out folder.
+- Mastoprint
+  - connects to the printer
+  - goes through each toot json in the out folder
+  - formats the toot with ESC/P commands
+  - sends the formatted toot to the printer
+  - moves the now-printed toot json file to the done folder
+
+These have been separated as the toots can come in way faster than the printer can print them.
+
+We're accessing the printer directly with ESC/P -- It doesn't have a queue. If you try to print while something else is trying to print, it errors.
+
+So Mastoprint acts as the print queue.
