 4. Modify the file named `config.json` or configure HedgeDoc through environment variables which will overwrite the configs, see docs [here](../configuration.md).
 5. **If using the release tarball for 1.7.0 or newer, this step can be skipped.**  
    Build the frontend bundle by `yarn run build` (use `yarn run dev` if you are in development)
-6. Modify the file named `.sequelizerc`, change the value of the variable `url` to your db connection string. For example:
-   - `postgres://username:password@localhost:5432/hedgedoc`
-   - `mysql://username:password@localhost:3306/hedgedoc`
-   - `sqlite:///opt/hedgedoc/hedgedoc.sqlite` (note that you need to use an absolute path to the SQLite file)
-7. It is recommended to start your server manually once: `NODE_ENV=production yarn start`, this way it's easier to see warnings or errors that might occur (leave out `NODE_ENV=production` for development).
