 ## Inspiration
 
-The inspiration for this app came from the inconvenience of constantly having to turn VPN off and on while on different networks. With there being no free solution to this problem, this app was created to meet that need.
+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
+* 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
-* Quick tile support for vpn toggling
+* Always-On VPN support
-* Dynamic shortcuts support for automation integration
+* Export tunnels to zip
-* Configurable Trusted Network list 
+* Quick tile support for VPN toggling
-* Optional auto connect on mobile data
+* Static shortcuts support for primary tunnel for automation integration
+* Intent automation support for all tunnels
 * 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
-$ ./gradlew assembleRelease
+```
+
+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
 ```
