+# Helium Bowser installer & updater
+## Overview
+### Helium_Helper.sh
+- Interactive installer and updater script
+- Installs to `/home/<USER>/.apps/Helium`  |  changeable in line 15 `INSTALL_PATH` 
+- Assumes: 
+    - Presence of `/home/<USER>/.apps/Helium` when updating  |  changeable in line 15 `INSTALL_PATH`
+    - Executable named `helium-browser.AppImage`  |  for convenience so launchers don't have to be edited at each update
+- Keeps prior AppImage as `helium-browser.OldAppImage` which will be replaced at every update
+
+### Helium_Auto_Update.sh
+- Automatic updater script for e.g. `cron`
+- Installs to `/home/<USER>/.apps/Helium`  |  changeable in line 8 `INSTALL_PATH`
