 ## Tool & Repository setup
 
-### Recommendations
-
-CI pipelines check all code changes when you open a PR. To not have to go back and fix all issues manually, the following setup is recommended.
-
 You will need the following tools:
 
 - [go](https://go.dev/). For the specific version used, check the [pre-commit workflow](.github/workflows/pre-commit.yml) at the `go-version` configuration
 - [pre-commit](https://pre-commit.com/)
 
-Once this is done, run the following:
-
-```sh
-# Linters used with pre-commit
-go install github.com/golangci/golangci-lint/cmd/golangci-lint@latest
-
-# Set up pre-commit hooks
-pre-commit install --hook-type commit-msg --hook-type pre-commit
-```
-
-### Hot reload
+Once those are installed, run `make setup` to perform the repository setup.
 
-If you want to hot reload the server, using `air` is recommended. Get it with
+## Development server
 
-```sh
-go install github.com/cosmtrek/air@latest
-```
-
-You can then run `GIN_MODE=debug air` in the repository root, which will build and rebuild the project every time the code changes.
+Run `make devserver` in the repository root, which will build and rebuild the project every time the code changes.
 
 ## Commit messages
 
 This project uses [Conventional commits](https://www.conventionalcommits.org/en/v1.0.0-beta.4/)
 to enable better overview over changes and enables automated tooling based on commit messages.
+
+## Tests & test coverage
+
+The test coverage goal is 100%. Please try to add tests for everything you add to the codebase. If in doubt, you’re always welcome to open an issue and ask for help.
+
+To run tests, run `make test`. To show the test coverage graphically in your browser, run `make coverage`.
