 You can also use the alias `rank` instead of `ranks`.
 
 Valid rank trackers are: `:alexa_country, :alexa_global, :alexa_us, :google, :moz_rank, :page_authority`. To get this you can do:
 
 ``` ruby
-    PageRankr.rank_trackers #=> [:alexa_country, :alexa_global, :alexa_us, :google, :moz_rank, :page_authority]
+    PageRankr.rank_trackers #=> [:alexa_us, :alexa_global, :alexa_country, :google, :moz_rank, :domain_authority, :page_authority]
 ```
 
 Alexa ranks are descending where 1 is the most popular. Google page ranks are in the range 0-10 where 10 is the most popular. If a site is unindexed then the rank will be nil.

 ## Rate limiting and proxies
 
 One of the annoying things about each of these services is that they really don't like you scraping data from them. In order to deal with this issue, they throttle traffic from a single machine. The simplest way to get around this is to use proxy machines to make the requests.
 
-In PageRankr >= 3.2.0, this is much simpler. The first thing you'll need is a proxy service. Two are provided [here](https://github.com/blatyo/page_rankr/tree/master/lib/page_rankr/proxy_services). A proxy service must define a `proxy` method that takes two arguments. It should return a string like `user:password@192.168.1.1:50501`.

A proxy service must define a `proxy` method that takes two arguments. It should return a string like `http://user:password@192.168.1.1:50501`.
 
 Once you have a proxy service, you can tell PageRankr to use it. For example:
 
 ``` ruby
     PageRankr.proxy_service = PageRankr::ProxyServices::Random.new([
-      'user:password@192.168.1.1:50501',
-      'user:password@192.168.1.2:50501'
+      'http://user:password@192.168.1.1:50501',
+      'http://user:password@192.168.1.2:50501'
     ])
 ```
 
 Once PageRankr knows about your proxy service, any request that is made will ask for a proxy from the proxy service. It does this by calling the `proxy` method. When it calls the `proxy` method, it passed the name of the tracker (e.g. `:ranks_google`) and the site that is being looked up. Hopefully, this information is sufficient for you to build a much smarter proxy service than the ones provided (pull requests welcome!).
