feat: migrate to forked lib

Migrated app to a forked version of wireguard-android to enable development work on features that require changes to the core lib, like #107 #104 #87 #52 #6

Improved first launch flow by change vpn permission to only launch on first tunnel start

Changed to proper database seeding strategy

Updated README to account for GitHub packages auth requirement

Migrated from deprecated UI components and libs

Bump versions

+The original inspiration for this app came from the inconvenience of having to manually turn VPN off
+and on while on different networks. This app was created to offer a free solution to this problem.
 
 ## Features
 
 * Add tunnels via .conf file, zip, manual entry, or QR code
-* Auto connect to VPN based on Wi-Fi SSID
+* Auto connect to VPN based on Wi-Fi SSID, ethernet, or mobile data
 * Split tunneling by application with search
-* Always-on VPN for Android support
+* WireGuard support for kernel and userspace modes
+* Always-On VPN support
 * Export tunnels to zip
 * Quick tile support for VPN toggling
 * Static shortcuts support for primary tunnel for automation integration
 * Intent automation support for all tunnels
-* Optional auto connect on mobile data, ethernet
 * Automatic service restart after reboot
-* Service will stay running in background after app has been closed
+* Battery preservation measures
 
+## Docs (WIP)
+
+Basic documentation of the feature and behaviors of this app can be found [here](https://zaneschepke.com/wgtunnel-docs/overview.html).
+
+The repository for these docs can be found [here](https://github.com/zaneschepke/wgtunnel-docs).
 
 ## Building
-    
+
 ```
 $ git clone https://github.com/zaneschepke/wgtunnel
 $ cd wgtunnel
+```
+
+Create a personal access token (classic) in GitHuv to be able to pull the wireguard-android github dependencies from GitHub packages
+as documented [here](https://docs.github.com/en/packages/learn-github-packages/introduction-to-github-packages#authenticating-to-github-packages).
+
+Alternatively, you can clone [wireguard-android](https://github.com/zaneschepke/wireguard-android) and run the following command to publish the dependency to your local maven repository (requires you have maven installed). This is the ideal approach
+if you intent to make changes to this lib.
+
+```
+$ git clone https://github.com/zaneschepke/wireguard-android
+$ cd wireguard-android
+$ brew install maven
+$ ./gradlew publishToMavenLocal
+```
+
+The [wireguard-android](https://github.com/zaneschepke/wireguard-android) dependency is a fork of the official [wireguard-android](https://github.com/WireGuard/wireguard-android) library. 
+
+Add the following lines to local.properties file:
+```
+GH_USER=<your github username>
+GH_TOKEN=<the personal access token with read package permission you just created>
+```
+
+And then build the app:
+```
 $ ./gradlew assembleDebug
 ```
