@superdav42 this is ready to be reviewed.

This is great! Thanks for updating the readme and everything. The only nitpick is the indention was changed for the entire composer.json file which caused conflicts. I undid the indention changes but preserved the additions.

Thanks!

@superdav42 so what rules are followed and how to set it up properly... i don't see anything in the project.

Maybe we should add linters for the project if we want to follow something. We can even implement something that runs all linter pre-commit.

For the most part the rules are in .phpcs.xml.dist but these don't really apply to json files. Really to follow the conventions set there, the json file should be update to use tabs instead of 4 spaces. I have no problem using 2 spaces in the composer.json file. The problem is it's hard to review what the content changes when there's so many white spaces changes.
