Update install instructions in README

Some people didn't know that ~/.local/bin has to be in PATH

I'm not sure whether it's sufficient. What if someone doesn't know what a PATH is, or how to add the path to PATH? Can we link something that explains everything?

Would this be enough? https://packaging.python.org/en/latest/tutorials/installing-packages/#installing-to-the-user-site

Maaybee. It's more than just explaining PATH etc, as it contains some useless information about installations. To see how to add something to the PATH, the user needs to go through one more link inside of it. It would be nice to have something better, but if not, I'm fine with this.

pip installs sinol-make executable in ~/.local/bin/ directory, so make sure it's in your PATH. Here's how to add a directory to PATH.

Slight suggestions:

installs sinol-make executable in -> installs the sinol-make executable in the

so make sure it's in your -> so make sure this directory is in your
