 ## Setting up for your local development environment
 
-You'll need a version manager for Ruby.  A version manager is a command-line tool which allows you to easily install, manage, and work with multiple ruby environments. We recommend [rvm](http://rvm.io), but [rbenv](https://github.com/sstephenson/rbenv) will work.

 ### Quickstart
 
-We're using a fork & pull model (see [Fork A Repo](https://help.github.com/articles/fork-a-repo) for an example), so fork this repo then clone the *forked* repo.

 To verify your environment is set up correctly, run the server

 ```
 rails s

 Go to http://localhost:3000/ and verify your success! You can play with the app locally to become more familiar with it.
 
 Pro-tip: Confirming Users Locally
-* outgoing emails are logged, so if you scroll back in your terminal window, you can see the contents of the confirmation email and copy/paste the confirmation link into your browser
-* or create a valid user for most recent signup, run `rails console`: `User.last.confirm!`

+To set up external authentication, create an oauth consumer on the site you want to authenticate with, then add [PROVIDER]\_OAUTH_KEY and [PROVIDER]\_OAUTH_SECRET value to the app environment.
 
 When developing locally, it is often helpful to set up **local.bridgetroll.org** to point at your localhost server via your [hosts file](https://en.wikipedia.org/wiki/Hosts_%28file%29). You can then tell the OAuth provider to use the url local.bridgetroll.org. Often, a separate OAuth consumer needs to be set up for each environment (localhost/staging/production), but some providers (like Facebook) allow a consumer set up as "www.bridgetroll.org" to function for any subdomain (like "local.bridgetroll.org").
