-ACC is designed to run out of the box, without user intervention. You can simply install it and forget. However, as I've been observing, most people will want to tweak settings - and everyone will want to know whether the thing is actually working.

 Alternatively, you can use a `text editor` to modify `/sdcard/acc/config.txt`. Changes to this file take effect almost instantly, and without a daemon restart.
 
-Notes/Tips for Front-end Developers
-- It's best to use full commands over short equivalents - e.g., `--set chargingSwitch` instead of `-s s`.
-- Follow auto-install/upgrade instructions in `moduleZip/install-latest.sh`.
-- Use provided config descriptions for ACC settings in the app. Include additional information (trusted) where appropriate.

+Use provided config descriptions for ACC settings in your app(s). Include additional information (trusted) where appropriate.
+
+
+### Auto-install ACC
+
+```
+1) Check whether ACC installed (exit code 0)
+which acc > /dev/null
+
+2) Download the installer (https://raw.githubusercontent.com/VR-25/acc/master/install-latest.sh)
+- e.g., curl -#L [URL] > [output file] (progress is shown)
+
+3) Run "sh [installer]" (progress is shown)
+```
+
+Notes
+
+- The installer must run as root (obviously).
