 The project is divided into two main components:
 
 1. **rust**: The libraries written in Rust.
-2. **python**: Python bindings for the Rust library.
+2. **bindings**: Bindings for the Rust library.
+   - _Python_ - Python bindings for our codelist tools

-#### Rust Library
+### Rust Library
 
 The Rust library is a collection of modules for working with medical codelists:
 
 - **codelists-rs**: Base library for working with codelists. This has basic
   structs and functions for working with codelists.
 - **codelist-validator-rs**: Library for validating codelists.
-- **codelist-builder-rs**: Library for building codelists.
+- **codelist-builder-rs**: Library for building codelists. 🚧 **Under Construction** 🚧

+## Development Utilities
+
+We use a [`justfile`](https://github.com/casey/just) to define common tasks for
+development and CI.
+
+### How to Install `just`
+
+Install `just` using
+[the instructions here](https://github.com/casey/just#installation), or with a
+package manager:
+
+```bash
+# macOS (Homebrew)
+brew install just
+
+# Debian or Ubuntu
+sudo apt install just
+
+# Arch Linux
+pacman -S just
+```
+
+### How to Use It
+
+To run a task, use:
+
+```bash
+just <recipe>
+```
+
+For example:
+
+```bash
+just ci
+```
+
+This will run the CI tasks defined in the `justfile`, which include running
+tests, formatting checks, and linting. You can also run individual tasks like
+
+```bash
+just fmt
+```
+
+These tasks help ensure consistent code style and formatting before committing
+or opening a pull request.
+
+To see all available tasks, run:
+
+```bash
+just --list
+```
+
+Make sure you run `just ci` before opening a pull request to ensure that all
+tasks pass. This will help catch any issues early and ensure that the code is
+formatted correctly and passes all tests.
 
 ## Formatting

 2. Open **Settings** and search for `Format On Save`.
 3. Enable **Editor: Format On Save**.
 4. Optionally, add a `.prettierrc` file to customize the formatting rules.
