We should document the potential journeys to guide users through setting up our various packages. I see three main paths:

1. I want to start linting my TypeScript project with ESLint

2. I am already linting my TypeScript project with TSLint and I want to switch to ESLint

3. I am converting my project from JavaScript to TypeScript and I want to keep using ESLint

I think breaking down the docs like this will make everything much more approachable.
