 # Helium Bowser installer & updater
+## Purpose
+This script was initially designed to just update my Helium browser but over time and interest it got more functional and universal. It includes functions to install, update, remove, add launcher, etc... and is distro independent.
+
+With "little" tinkering it should be possible to apply this script to install, update & configure many kinds of releases from source, like Debian packages, AppImages, binaries, etc...
+## Usage
+Help
+```sh
+./helium_helper.sh -h
+```
+### First Install
+To initally install Helium browser via this script, download helium_helper.sh and make it executable:
+```sh
+wget https://lab.c95.org/fr4nz/helium-helper/raw/branch/main/helium_helper.sh && chmod +x helium_helper.sh
+```
+Run script with install parameter _-i_
+```sh
+./helium_helper.sh -i
+```
+Add alias to `.shellrc` | _optional_
+```sh
+./helium_helper.sh -a   ### ONLY TESTED WITH zsh & bash
+```
+---
+### Updating
+**From launcher** (if added)
+
+Checking for the latest version and updating can simply be done for the browser as well as the script by right clicking the app icon and choosing either update option, which will be run by `helium_launcher_update.sh`. This will backup all files that are being updated and write a log.
+
+**Terminal**
+
+Updating can also be done by running:
+```sh
+./helium_helper.sh -u   ### UPDATE APP
+```
+```sh
+./helium_helper.sh -S   ### UPDATE SCRIPT
+```
+Since this script is interactive, it doesn't keep logs.
 ## Overview
 ### Helium_Helper.sh
-- Interactive installer and updater script
-- Installs to `/home/<USER>/.apps/Helium`  |  changeable in line 27 `INSTALL_PATH` 
+- Interactive installer, updater & configuration script
+- Installs to `/home/<USER>/.apps/Helium`  |  changeable in line 28 `INSTALL_PATH` 
 - Assumes: 
-    - Presence of `/home/<USER>/.apps/Helium` when updating  |  changeable in line 27 `INSTALL_PATH`
-    - Executable named `Helium.AppImage`  |  for convenience so launchers don't have to be edited at each update
-- Keeps prior AppImage as `Helium.old` which will be replaced at every update
+    - Presence of `/home/<USER>/.apps/Helium` when updating  |  changeable in line 28 `INSTALL_PATH`
+    - Executable named `Helium.AppImage`

+    - `helium_launcher_update.sh` --> `helium_launcher_update.sh.old`
+    - `Helium.desktop` --> `Helium.desktop.old`
+    which will be overwritten at every update
 - Adds desktop launcher to `/home/<USER>/.local/share/applications`
-
-### Helium_Auto_Update.sh
-- Automatic updater script
-- Installs to `/home/<USER>/.apps/Helium`  |  changeable in line 8 `INSTALL_PATH` 
+- Adds options to launcher which are run by `helium_launcher_updater.sh`
+    - Update Helium
+    - Update Script
+    - View Log
+- Run `helium_helper.sh -h` for help
+---
+### Helium_Launcher_Update.sh
+- Update Helium from launcher
 - Assumes: 
-    - Presence of `/home/<USER>/.apps/Helium` when updating  |  changeable in line 8 `INSTALL_PATH`
-    - Executable named `helium-browser.AppImage`  |  for convenience so launchers don't have to be edited at each update
-- Loggs to `/home/<USER>/.apps/Helium/updateLog`
-- Keeps prior AppImage as `helium-browser.OldAppImage` which will be replaced at every update
