+Credential Providers
+====================
+
+These library interfaces are used to deal with allocating credentials on demand
+either dynamically by calling keystone to allocate new credentials, or from
+a list of preprovisioned credentials. These 2 modules are implementations of
+the same abstract credential providers class and can be used interchangably.
+However, each implementation has some additional parameters that are used to
+influence the behavior of the modules. The API reference at the bottom of this
+doc shows the interface definitions for both modules, however that may be a bit
+opaque. You can see some examples of how to leverage this interface below.

+This function just returns an initialized credential provider class based on the

+
+Dealing with Credentials
+------------------------
+
+Once you have a credential provider object created the access patterns for
+allocating and removing credentials are the same across both the dynamic
+and preprovisioned credentials. These are defined in the abstract
+CredentialProvider class. At a high level the credentials provider enables
+you to get 3 basic types of credentials at once (per object): a primary, alt,
+and admin. You're also able to allocate a credential by role. These credentials
+are tracked by the provider object and delete must manually be called otherwise
+the created resources will not be deleted (or returned to the pool in the case
+of preprovisioned creds)
+
+Examples
+''''''''
+
+Continuing from the example above, to allocate credentials by the 3 basic types
+you can do the following::
+
+  provider = get_credentials_provider('my_tests')
+  primary_creds = provider.get_primary_creds()
+  alt_creds = provider.get_alt_creds()
+  admin_creds = provider.get_admin_creds()
+  # Make sure to delete the credentials when you're finished
+  provider.clear_creds()
+
+To create and interact with credentials by role you can do the following::
+
+  provider = get_credentials_provider('my_tests')
+  my_role_creds = provider.get_creds_by_role({'roles': ['my_role']})
+  # provider.clear_creds() will clear all creds including those allocated by
+  # role
+  provider.clear_creds()
+
+When multiple roles are specified a set of creds with all the roles assigned
+will be allocated::
+
+  provider = get_credentials_provider('my_tests')
+  my_role_creds = provider.get_creds_by_role({'roles': ['my_role',
+                                                        'my_other_role']})
+  # provider.clear_creds() will clear all creds including those allocated by
+  # role
+  provider.clear_creds()
+
+If you need multiple sets of credentials with the same roles you can also do
+this by leveraging the ``force_new`` kwarg::
+
+  provider = get_credentials_provider('my_tests')
+  my_role_creds = provider.get_creds_by_role({'roles': ['my_role']})
+  my_role_other_creds = provider.get_creds_by_role({'roles': ['my_role']},
+                                                   force_new=True)
+  # provider.clear_creds() will clear all creds including those allocated by
+  # role
+  provider.clear_creds()
