First draft at README.md

[readysetagile]

As a FCC Columbus contributor
I want to see some instructions on the group's main repository
So that I can get an idea of how I can contribute

modify the README.md file as needed. might need links to other markdown files in the repo.

• From amygnb: There are some recommendations for adding Prettier and ESLint extensions to your IDE that would probably be helpful to document in the README.md. The Prettier extension will auto-format on save, which is nice, so that you don't have to wait to have your files formatted in the pre-commit git hook. The ESLint extension will highlight linting warnings and errors as you code, so again, you don't have to wait for that feedback in the pre-commit hook.

Both Prettier and ESLint are configurable, but I left them mostly with just the defaults.

There's a list of "supported editors" on the Prettier site (https://prettier.io/). I've really only ever used VSCode, but I'm assuming that means there are extensions available for the other editors listed. ESLint also has editor integrations, listed here: https://eslint.org/docs/latest/user-guide/integrations#editors
