+### Retries
+Simple interface to retry requests that are known to fails sometimes.  To add a retry wrap the code like this:
+
+```
+DaemonRunner::RetryErrors.retry do
+  my_not_so_good_network_service_that_fails_sometimes
+end
+```
+
+* `options` - Options hash to pass to `retry` (**optional**)
+    * :retries - Number of times to retry an exception (**optional**, _default_: 3)
+    * :exceptions - Array of exceptions to catch and retry (**optional**, _default_: `[Faraday::ClientError]`)
+
+### Locking
+Locking can be done either via an exclusive lock or a semaphore lock.  The major difference is that with a semaphore lock you can define how many nodes can obtain the lock.
+
+#### Exclusive Lock
+**TBD**
+
+#### Semaphore Lock
+For an example of how to implement semaphore locking take a look at the [example](/examples/example_semaphore.rb)

 ## Development
 
 After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake test` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
 
 To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
