 # Development
 
+# Developer Usage Guide for ACMC
+
+## Installation
+To install the ACMC package for development, ensure you have Python 3.9 or later installed.
+
+### Clone the Repository
+```sh
+git clone https://git.soton.ac.uk/meldb/concepts-processing.git
+cd concepts-processing
+```
+
+### Set Up a Virtual Environment
+It is recommended to use a virtual environment to manage dependencies.
+
+```sh
+python -m venv venv
+source venv/bin/activate  # On Windows use `venv\Scripts\activate`
+```
+
+### Install Dependencies
+Using `hatch`, you can install the necessary dependencies easily.
+
+```sh
+pip install --upgrade pip
+pip install hatch
+```
+This will create a virtual environment with all required dependencies.
+
+## Development Environment
+
+### Activate the Development Environment
+To enter the development environment, use:
+
+```sh
+hatch shell
+```
+
+### Code Formatting
+The project uses `black` for code formatting. Ensure your code is properly formatted before committing:
+
+```sh
+black acmc
+```
+
+### Type Checking
+The project uses `mypy` for type checking:
+
+```sh
+mypy acmc
+```
+
+### Running Tests
+Run tests using `pytest`:
+
+```sh
+hatch run pytest
+```
+
+## Building the Package
+To build the package, use:
+
+```sh
+hatch build
+```
+
+## Running the CLI
+The package provides a command-line interface (CLI) entry point. To run it:
+
+```sh
+acmc --help
+```
+
+## Contributing
+If you make changes, ensure all tests pass and code formatting is correct before submitting a merge request.
+
+1. Create a new branch for your feature or bugfix:
+   ```sh
+   git checkout -b feature-branch
+   ```
+2. Make changes and commit them:
+   ```sh
+   git add .
+   git commit -m "Description of changes"
+   ```
+3. Push your branch:
+   ```sh
+   git push origin feature-branch
+   ```
+4. Open a merge request in GitLab.
