 Since `makesure` is a tiny utility represented by a single file, the recommended installation strategy is to keep it local to a project where it's used (this means in code repository). Not only this eliminates the need for repetitive installation for every dev on a project, but also allows using separate `makesure` version per project and update only as needed.
