Install plugins in your non-Docker development environment

(This guide only covers non-docker dev install. For Docker dev :whale: see https://meta.discourse.org/t/beginners-guide-to-install-discourse-for-development-using-docker/102009?u=merefield)
If you've followed the instructions to set up your local discourse, you can install a plugin locally:
Stop your local server if it's running.
Download the plugin repo and save it your 
/plugins folder. Alternatively, you can use a symlink.
If the plugin includes migrations (you'll see them in 
db/migrate), run them with: 
LOAD_PLUGINS=1 bundle exec rake db:migrate from discourse root, not the plugin folder.
Re-start the server.
If the plugin has settings, you can edit them by going to 
http://localhost:3000/admin/plugins and clicking on "Settings" next to its name.
If you'd like to install a plugin in production, follow this guide.
