List all commands in a help output

If using make as a task runner it’s a good idea to document all individual tasks and make it easy to get that documentation. That can be done with using a task itself that parses the file and looks for ## comments

.PHONY: help
help:
	@grep -E '^[0-9a-zA-Z_-]+:.*?## .*$$' $(MAKEFILE_LIST) | \
	  sort | \
	  awk 'BEGIN {FS = ":.*?## "}; {printf "\033[36m%-30s\033[0m %s\n", $$1, $$2}'

.PHONY: build
build:  ## Build
    echo build steps

.PHONY: run
run:  ## Run the code app
	echo run my code
