 # Cookiecutter Python Package
 
-A [Cookiecutter](https://github.com/cookiecutter/cookiecutter) template for a Python package with Poetry as the dependency manager.
+A [Cookiecutter](https://github.com/cookiecutter/cookiecutter) blank template for a project.
 
 **NOTE:** Only Python 3.8+ is supported.
 
 ---
 
 ## Features
-- Hooks: Pre-commit
-- Formatters and Linters: Black, Flake8, Flake8-bugbear, Isort, and Lizard
+- Package manager: pip
+- Formatters and Linters: Ruff
 - Testing Frameworks (Optional): Pytest, Coverage, and CovDefaults
 
 ## Usage
 
-- Since this template uses Poetry as the dependancy manager, install poetry from `https://python-poetry.org/docs/#installation`
-
-- Install the `cookiecutter` library.
-
-    ```python
-    pip install cookiecutter
-    ```
-    OR
-    ```python
-    python -m pip install cookiecutter
-    ```
-
-- Run the command:
-    ```python
-    cookiecutter https://github.com/gurashish1singh/cookiecutter-python.git
-    ```
-    OR
-    ```python
-    python -m cookiecutter https://github.com/gurashish1singh/cookiecutter-python.git
-    ```
+- bash setup.sh
+
 - This template uses post-project generation hooks to:
    - Initialize a git repository (with default branch as main), IF the working directory is not already a git repository.
 
      **NOTE**: You will have to create a repositry on remote if it doesn't already exist before running the cookiecutter command.
-   - Create a Poetry virtualenv
-   - Install all dependencies
-   - Install the pre-commit and pre-push hooks
+   - Create a python virtual environment and activate it
+   - Install ruff
+   - Include an initial lint github workflow
