+Qwik Optimizer remake
 
 **_DISCLAIMER_**: This is very much a work in progress so expect this space to change a lot.
 
 ## What
+
 This is a ground up re-implementation of the original Qwik Optimzer.
 
 ## Why
-The decision was made to mover from SWC to Oxide as the foundation for the Qwik Optimizer.  
 
-In the process of doing this, we hope to make the internal Qwik Optimizer more modular and to be more idiomatic Rust.

 Not much save for the unit tests.
 
+## Nix
+
+If you have Nix installed, you can enter a development shell with all the necessary dependencies by running:
+
+```bash
+nix develop
+```
+
+You can also install `direnv` and have it automatically load the development environment when you enter the project directory:
+
+```bash
+direnv allow
+```
