+2. find a visual studio code theme, convert it to json (if it is not already
+ json) and put it at `~/.config/babi/theme.json`
## demos
-not much works yet, here's a few things
+most things work! here's a few screenshots
### file view
-this opens the file, displays it, and can be edited in some ways and can save!
-movement is currently enabled through the arrow keys, home + `^A`, end + `^E`,
-and some key combinations are detected. unknown keys are displayed as errors
-in the status bar. babi will scroll if the cursor goes off screen either from
-resize events or from movement. babi can edit multiple files. babi has a
-command mode (so you can quit it like vim `:q`!).
