# Contributing > "First, thanks for considering to contribute to my project. It really means a lot!" - [@andrasbacsai](https://github.com/andrasbacsai) You can ask for guidance anytime on our [Discord server](https://coollabs.io/discord) in the `#contribution` channel. ## 1) Setup your development environment - You need to have Docker Engine (or equivalent) [installed](https://docs.docker.com/engine/install/) on your system. - For better DX, install [Spin](https://serversideup.net/open-source/spin/). ## 2) Set your environment variables - Copy [.env.development.example](./.env.development.example) to .env. ## 3) Start & setup Coolify - Run `spin up` - You can notice that errors will be thrown. Don't worry. - If you see weird permission errors, especially on Mac, run `sudo spin up` instead. - Run `./scripts/run setup:dev` - This will generate a secret key for you, delete any existing database layouts, migrate database to the new layout, and seed your database. ## 4) Start development You can login your Coolify instance at `localhost:8000` with `test@example.com` and `password`. Your horizon (Laravel scheduler): `localhost:8000/horizon` - Only reachable if you logged in with root user.
