 Get replication lag in seconds

+Most of the time, Makara does a great job automatically routing queries to replicas. If it incorrectly routes a query to primary, you can use:
+
+```ruby
+distribute_reads(replica: true) do
+  # send all queries in block to replica
+end
+```
+
+## Rails 6
+
+Rails 6 has [native support for replicas](https://edgeguides.rubyonrails.org/active_record_multiple_databases.html) :tada:
+
+```ruby
+ActiveRecord::Base.connected_to(role: :reading) do
+  # do reads
+end
+```
+
+However, it’s not able to automatically route queries like Makara just yet.
 
 ## Thanks
 
 Thanks to [TaskRabbit](https://github.com/taskrabbit) for Makara, [Sherin Kurian](https://github.com/sherinkurian) for the max lag option, and [Nick Elser](https://github.com/nickelser) for the write-through cache.
