+## Development setup
+
+There are two ways to setup the development environment.
+
+- Using the Docker Compose setup provided in this repository.
+- Using [hatch](https://hatch.pypa.io/) in your host OS.
+
+
+### Using Docker Compose
+
+Working with the Docker Compose setup is made easy with the `Makefile` provided in the repository.
+
+#### Requirements
+
+- Docker
+- docker compose plugin
+
+#### Setup
+
+1. Setup .env file
+
+An example .env file is provided in the repository. You can copy it to .env file using the following command:
+
+```bash
+cp .env.example .env
+```
+
+The default values in the .env file are suitable for the docker-compose setup.
+
+2. Migrate
+
+```bash
+make migrate
+```
+
+3. Run the development server
+
+```bash
+make run
+```
+
+### Using hatch
+
+#### Requirements
+
+- Python 3.12 or higher
+- [hatch](https://hatch.pypa.io/) (Recommended way to install is using `pipx install hatch`)
+- A running PostgreSQL server
+
+#### Setup
+
+1. Setup .env file
+
+An example .env file is provided in the repository. You can copy it to .env file using the following command:
+
+```bash
+cp .env.example .env
+```
+
+Edit the .env file and set the values for the environment variables, especially the database variables.
+
+2. Run migrate
+
+```bash
+hatch run dev:migrate
+```
+
+3. Run the development server
+
+```bash
+hatch run dev:server
+```
