Other recipes can be run by supplying their name as an argument, for example `j build` to run the `build` recipe.

-`j` looks upward from the current directory for a file called `justfile` and then runs make with that file as the makefile. `j` also sets the current working directory to where it found the justfile, so your commands are executed from the root of your project and not from whatever subdirectory you happen to be in.

 Makefile targets are called "recipes", and are simply lists of commands to run in sequence, making them very concise. Recipes stop if a command fails, like if you do `set -e` in a shell script. Recipes also print each command before running it. If you would like to supress this, you can prepend a line in a recipe with `@`.

 On a big project with multiple contributers, it's very useful to have a file with all the commands needed to work on the project. There are probably different commands to test, build, lint, deploy, and the like, and having them all in one place is useful and cuts down on the time you have to spend telling people which commands to run and how to type them. And, with an easy place to put commands, it's likely that you'll come up with other useful things which are part of the project's collective wisdom, but which aren't written down anywhere, like the arcane commands needed for your project's revision control workflow, for updating dependencies, or all the random flags you might need to pass to the build system.
