-Sway is an incredible window manager, and certainly one of the most well established wayland window managers. However, it is restricted to only include the functionality that existed in i3. This fork ditches the simple wlr_renderer, and extends it to render fancy GLES2 effects. This, along with a couple of minor changes, expands sway's featureset to include the following:
+Sway is an incredible window manager, and certainly one of the most well established wayland window managers. However, it is restricted to only include the functionality that existed in i3. This fork ditches the simple wlr_renderer, and replaces it with our fx_renderer, capable of rendering with fancy GLES2 effects. This, along with a couple of minor changes, expands sway's featureset to include the following:
 
 + **Anti-aliased rounded corners, borders, and titlebars**
 + **Scratchpad treated as minimize**: Allows docks, or panels with a taskbar, to correctly interpret minimize / unminimize requests ([thanks to LCBCrion](https://github.com/swaywm/sway/issues/6457))
 + **Add a nix flake to the repo**: Allows nixos users to easily contribute to and test this project

+## Installation
+
+### Compiling from Source
+
+This project contains a nix flake for those who have the nix package manager installed. This flake handles installing the below dependencies when `nix develop` is ran inside of the project root. Otherwise, the below dependencies must be installed prior to building and running this project.
+
+Install dependencies:
+
+* meson \*
+* wlroots
+* wayland
+* wayland-protocols \*
+* pcre
+* json-c
+* pango
+* cairo
+* gdk-pixbuf2 (optional: system tray)
+* [scdoc] (optional: man pages) \*
+* git (optional: version info) \*
+
+_\* Compile-time dep_
+
+Run these commands:
+
+    meson build/
+    ninja -C build/
+    sudo ninja -C build/ install
+
+On systems without logind nor seatd, you need to suid the sway binary:
+
+    sudo chmod a+s /usr/local/bin/sway
+
+SwayFX will drop root permissions shortly after startup.
+
+## Contributing
+
+SwayFX would love to receive any new features that you're willing to build! Generally, we'd like to focus on eye-candy type improvements to keep our scope appropriate. If you'd like to build something that you think may be out of that focus, please raise an issue and we can discuss whether or not it will fit within this project.
+
+Here's a quick outline of where most of our changes lie vs the main sway repository:
++ `sway/desktop/render.c`: the file that handles calling `fx_renderer` to render to the screen, handles damage tracking and scaling
++ `sway/desktop/fx_renderer.c`: the meat and potatoes of this project, structured as similarly to wlr_renderer as possible
++ `sway/desktop/shaders`: where all of the shaders that fx_renderer uses live
