 ### Requirements

 Requirements for testing are generally included in the Go installation and the project, but its generally recommended to also install;
+
 - the language server [`gopls`](https://pkg.go.dev/golang.org/x/tools/gopls)
 - the linters runner [`golangci-lint`](https://github.com/golangci/golangci-lint) (we run it in our CI pipeline so its a requirement for merging), to enable running `make lint`.
 
 ### Testing
+
 All tests and a coverage check is run when calling the command;
+
 - `make test`
 
 We have a mininum test coverage limit at 95%.
 
 ### Linting

 To keep the project tidy we use `golangci-lint`, please run it during development to ensure an accaptable PR;
