 ## [Unreleased]
+### Changed
+- Updated build script (`addons/godot_xterm/native/build.sh`). Git submodules will now be initialized if they haven't already. Moved nix-shell related stuff to a seperate shell.nix file so the same build command can be used on all Linux based OSes.

 ### All Operating Systems
 
-**Important**: The main dependencies of this project are included as git submodules.
+You will need at least these dependencies in order to build this plugin:
-You can install them in this repo after cloning with:
+- Git (for git submodules)
-```
-git submodule update --init --recursive
-```
-In addition to these, you will need some other dependencies including:
 - a C++ compiler (e.g. gcc)
 - ar (part of GNU Binutils)
 - CMake
 - Python
 - SCons
 
-### Operating System Specific
+### Linux
 
 #### NixOS
-On NixOS you can simply run the [build.sh] script in the `addons/godot_xterm/native` directory:
+You can simply run the [build.sh] script in the `addons/godot_xterm/native` directory:
 ```
-cd addons/godot_xterm/native
+addons/godot_xterm/native/build.sh
-./build.sh
 ```
 All dependencies will be pulled in by nix-shell and the build steps will run.
 
 #### Arch Linux and Ubuntu
-See the [Arch Linux Dockerfile](dockerfiles/archlinux) and [Ubuntu Dockerfile](dockerfiles/ubuntu) for a list of packages that need to be installed. Once installed, run the [build.sh] script from the `addons/godot_xterm/native` directory:

-Make sure you use `bash` to run the script as the default interpreter is set to nix-shell. 
 
-#### Other
+#### Other Linux Distributions
-Other operating systems will probably be similar to the above. When in doubt check the documentation in the submodule repos, the [build.sh] script, and the [SConstruct] file.
