-### Setup
+### Installation
 
 1.  **Clone the repository:**
-
     ```sh
     git clone https://github.com/BruinGrowly/Python-Code-Harmonizer.git
     cd Python-Code-Harmonizer
     ```
 
-2.  **Ensure all files are present:**
-
-      * `divine_invitation_engine_V2.py` (The Engine)
-      * `ast_semantic_parser.py` (The Parser)
-      * `anchor_analysis_V2.py` (The Proof)
-      * `PythonCodeHarmonizer.py` (The Application)
-
-### Step 1: Run the "Proof"
-
-First, you can validate the V2 engine and its "Anchor Point" axiom by running the harmonized analysis script.
-
-```sh
-python anchor_analysis_V2.py
-```
-
-*(You should see a successful report validating the (1,1,1,1) Anchor Point.)*
+2.  **Install the project:**
+    *   This project is packaged and can be installed using `pip`. It is recommended to do this in a virtual environment.
+    ```sh
+    pip install .
+    ```
 
-### Step 2: Run the "Harmonizer"
+### Running the Harmonizer
 
-Second, use the Harmonizer to analyze any Python file. You can test it on the included `examples/test_code.py` file:
+Once installed, the Harmonizer can be run from the command line using the `harmonizer` script. You can test it on the included example file:

+## Development & Contribution
+
+This project is now equipped with a full suite of professional development tools to ensure code quality and stability.
+
+### Setup for Development
+
+If you wish to contribute, please install the project in "editable" mode along with the development dependencies:
+
+```sh
+# It is recommended to use a virtual environment
+pip install -r requirements.txt
+pip install -e .
+```
+
+### Running Tests and Quality Checks
+
+*   **Run the full test suite:**
+    ```sh
+    pytest
+    ```
+*   **Run code quality checks:**
+    *   This project uses `pre-commit` to automatically run `black`, `flake8`, and `isort`. To run the checks manually:
+    ```sh
+    pre-commit run --all-files
+    ```
