 ## API:
 Everything is controlled via HTTP requests.
-Currently there is just one "endpoint" that sets RGB colors in a certain mode:
-`GET 127.0.0.1:21371/set/{mode}/{r}/{g}/{b}`
+Endpoints:
+
+`GET 127.0.0.1:21371/set/{mode}/{r}/{g}/{b}` - Sets color for `mode`
+`GET 127.0.0.1:21371/get/{mode}` - Gets color for `mode` in `{r}:{g}:{b}\n` format
+
 With `mode` being:
 - `charging`, meaning device charging and below 90% battery capacity
 - `low_bat`, meaning device having battery capacity between 0 and 20%
