Setup is pretty simple.
First run bundle install
to install Ruby dependencies.
When this is done, run
rails db:create db:migrate
To get your database set up.
Then run rails s
to serve the app and go to localhost:3000
to write some posts.
You will need to run rails tailwindcss:watch
as a standalone process for the app to pick up changes in tailwind classes as you develop the app. Click here to read more about this.
