 ### IndifferentAccess
 
-This extension can be mixed in to instantly give you indifferent access to your Hash subclass. This works just like the params hash in Rails and other frameworks where whether you provide symbols or strings to access keys, you will get the same results.
+This extension can be mixed in to your Hash subclass to allow you to use Strings or Symbols interchangeably as keys; similar to the `params` hash in Rails.
 
-A unique feature of Hashie's IndifferentAccess mixin is that it will inject itself recursively into subhashes *without* reinitializing the hash in question. This means you can safely merge together indifferent and non-indifferent hashes arbitrarily deeply without worrying about whether you'll be able to `hash[:other][:another]` properly.
+In addition, IndifferentAccess will also inject itself into sub-hashes so they behave the same.
+
+Example:
+
+```ruby
+class MyHash < Hash
+  include Hashie::Extensions::MergeInitializer
+  include Hashie::Extensions::IndifferentAccess
+end
+
+myhash = MyHash.new(:cat => 'meow', 'dog' => 'woof')
+myhash['cat'] # => "meow"
+myhash[:cat]  # => "meow"
+myhash[:dog]  # => "woof"
+myhash['dog'] # => "woof"
+
+# Auto-Injecting into sub-hashes.
+myhash['fishes'] = {}
+myhash['fishes'].class # => Hash
+myhash['fishes'][:food] = 'flakes'
+myhash['fishes']['food'] # => "flakes"
+```

Subject: [PATCH 03/13] Fix `#merge` breaking indifferent access

`HashWithDifferentAccess` wasn't properly setting the indifferent
access when merging in other hashes. This reruns `#convert!` after
calling the superclass implementation of the method, so it preserves
indifferent access on the resulting object.

Fixes #345

+Add a line to [CHANGELOG](CHANGELOG.md) under *Unreleased*. Make it look like every other line, including your name and link to your Github account.
+
+There are several categorizations of changes that you can choose from. Add your line to the appropriate section, following these conventions:
+
+* **Added** - When you add a new behavior to any class or module (or add a new extension) that does not break backwards compatibility, you should mark it as "added". This is generally a fully new behavior that does not touch any pre-existing public API. Changes here require a MINOR version bump, following the Semantic Versioning specification.
+* **Changed** - You should mark any change to the behavior of a public API on any class or module as "changed". Changes here require a MAJOR version bump, following the Semantic Versioning specification.
+* **Deprecated** - Any time you deprecate part of the public API on any class or module you should mark the change as "deprecated". Deprecated behavior will be removed in the next MAJOR version bump, but should be left in until then. Changes here require a MINOR version bump, following the Semantic Versioning specification.
+* **Removed** - You should mark any behavior that you removed from a public API on any class or module as "removed". Changes here require a MAJOR version bump, following the Semantic Versioning specification.
+* **Fixed** - Any time you fix a bug you should mark as "fixed". Changes here require a PATCH version bump.
+* **Security** - You should mark any security issue that you fix as "security". Changes here require a PATCH version bump.
+* **Miscellaneous** - Mark any other changes you make (i.e. documentation updates, test harness changes, etc.) as "miscellaneous". Changes here require a PATCH version bump.
