+## Development Setup
+
+There are two ways to set up your development environment for this project. You can choose the one that suits you best.
+
+### Option 1: Using venv and requirements.txt
+
+1. Clone the repository to your local machine.
+2. Navigate to the project directory.
+3. Create a virtual environment using `venv` by running the following command:
+
+    ```bash
+    python -m venv venv
+    ```
+
+4. Activate the virtual environment:
+
+    - On Windows, run:
+
+        ```bash
+        .\venv\Scripts\activate
+        ```
+
+    - On Unix or MacOS, run:
+
+        ```bash
+        source venv/bin/activate
+        ```
+
+5. Install the required packages from `requirements.txt`:
+
+    ```bash
+    pip install -r requirements.txt
+    ```
+
+### Option 2: Using Poetry
+
+1. If you don't have Poetry installed, you can install it by following the instructions on the [official Poetry website](https://python-poetry.org/docs/#installation).
+2. Clone the repository to your local machine.
+3. Navigate to the project directory.
+4. Install the project dependencies with Poetry:
+
+    ```bash
+    poetry install
+    ```
+
+5. Activate the Poetry environment:
+
+    ```bash
+    poetry shell
+    ```
+
+## Setting up pre-commit
+
+`pre-commit` is a tool that we use to maintain high-quality code in this project. It runs checks (hooks) on your code each time you commit changes. Here's how to set it up:
+
+
+1. In the project directory, run the following command to install the `pre-commit` hooks:
+
+    ```bash
+    pre-commit install
+    ```
+
+2. You can run all pre-commit hooks on all files with:
+
+    ```bash
+    pre-commit run --all-files
+    ```
+
+After this, `pre-commit` will automatically run the hooks each time you commit changes to the project. If any of the hooks fail,
+you'll need to fix the issues and then try committing your changes again.
+
+Also some of hooks are auto fixed if you see file was modified after running `pre-commit run --all-files` then you can add the changes and commit again.

 #### As mentioned before, this project is still in the early stages of development. If you'd like to contribute by adding functionality, we recommend opening an issue first to discuss your proposed functionality and the best ways to implement it.
