GitHub Tool of the Day.
Every day we take one trending GitHub project, install it for real, and write down exactly what it does, the commands that actually work, and whether it earns a place in your stack. No wrappers around a README: each guide comes from a working install, including the parts that broke.
The problem with most tool write-ups is that they are the README rearranged. You finish reading and still do not know whether the thing works, what it costs you to run, or which step quietly fails on a machine that is not the author's. So we run it first and report what happened.
Every guide follows the same shape: what the tool is for, the exact install commands, the configuration that is not optional, the gotcha that cost us time, and an honest verdict on whether to keep it. Where a tool is not worth it, we say so — a recommendation only means something if we are willing to publish the other answer.
