Added steps for install from the blog post

Initial setup isn't completely clear from the docs, so I've taken the language from the blog [post here](https://nystudio107.com/blog/database-asset-syncing-between-environments-in-craft-cms) and put them in the readme. They're nice concise instructions, and it seems to make sense to put them inline with the repo.

Open to suggestions, let me know what you think, these scripts are an absolute lifesaver
