-## How to build Trinity with these Files
+This directory contains all the required scripts to build TDE packages for Arch Linux.
+Please acquaint yourself with the build scripts and the PKGBUILDs if you also intend to package the builds.
+
+## Building
+
+If building all the build packages, please run `./build_tde.sh all` which will invoke `makepkg` on all of the PKGBUILDs in the `packages` directory.
+
+Refer to `./build_tde.sh -h` for other 
+### Building a Single Package
 If you have trouble building one of these packages,
-please source the environment variables by issuing (from package directory):
+please source the environment variables by issuing (from `packages` directory):
 ```
 . ../environment
-```
-OR
-```
+
+# Or:
+
 source ../environment
+
+# Run makgepkg after
 ```
+Note that this is only needed for building individual packages as the `built_tde.sh` script sources `environment` automatically
+
+## Packaging Information
 
-The Build Script build.sh will automatically source this environment and is not needed to be ran beforehand
+When verifying that the packages or the PKGBUILDs are good for packaging for distribution, 
+please familarize yourself with Arch Linux provided documentation.
 
-## Building the Trinity Packages
-All you need to do is run ./build.sh after installing any dependencies. A Docker Script is included to create
-a temporary build environment for Trinity. It is recommended to use this Docker Environment as this is how
-the official trinity arch repo is compiled by. See the README.md in DockerBuildEnvironment for details.

-## Unbuildable Packages
+## General Tips
+
+### Keep Your System up to Date
+
+You're using a rolling release distro, please ensure you run `# pacman -Syu` as needed.
+
+### Errors With Java
+
+Arch Linux uses OpenJDK as the provider for compiling Java programs and so should be installed on your system.
+If needed, please [change the default java enviroment](https://wiki.archlinux.org/title/Java#Change_default_Java_environment) to comply with Java requirements.
+
+### Reforming PKGBUILDs
+
+If you feel like a PKGBUILD needs changes, please refer to the Arch Wiki for guidlines.
+Also refer to the [AUR](https://aur.archlinux.org/) for PKGBUILDs currently provided for references on how maintainers use them.
+
+### Unbuildable Packages
 Here lists the unbuildable packages at the moment. Please help make these packages buildable and submit any pull
 requests to fix them. Each package has a Bug entry which includes the build log for reference.
+
+Also refer to [TDE Module Quirks and Known Bugs](https://wiki.trinitydesktop.org/How_to_Build_TDE_Core_Modules#Quirks_and_Known_Bugs) if a particular package is currently unbuildable.
