+# AFOAuth2Manager
+
+AFOAuth2Manager is an extension for [AFNetworking](http://github.com/AFNetworking/AFNetworking/) that simplifies the process of authenticating against an [OAuth 2](https://tools.ietf.org/html/rfc6749) provider.
+
+## Example Usage
+
+### Authentication
+
+```objective-c
+NSURL *baseURL = [NSURL URLWithString:@"http://example.com/"];
+AFOAuth2Manager *OAuth2Manager =
+            [[AFOAuth2Manager alloc] initWithBaseURL:baseURL
+                                            clientID:kClientID
+                                              secret:kClientSecret];
+
+[OAuth2Manager authenticateUsingOAuthWithURLString:@"/oauth/token"
+                                          username:@"username"
+                                          password:@"password"
+                                             scope:@"email"
+                                           success:^(AFOAuthCredential *credential) {
+                                               NSLog(@"Token: %@", credential.accessToken);
+                                           }
+                                           failure:^(NSError *error) {
+                                               NSLog(@"Error: %@", error);
+                                           }];
+```
+
+### Authorizing Requests
+
+```objective-c
+AFHTTPSessionManager *manager =
+    [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL];
+
+[manager.requestSerializer setAuthorizationHeaderFieldWithCredential:credential];
+
+[manager GET:@"/path/to/protected/resource"
+  parameters:nil
+    progress:nil
+     success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
+         NSLog(@"Success: %@", responseObject);
+     }
+     failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
+         NSLog(@"Failure: %@", error);
+     }];
+```
+
+### Storing Credentials
+
+```objective-c
+[AFOAuthCredential storeCredential:credential
+                    withIdentifier:serviceProviderIdentifier];
+```
+
+### Retrieving Credentials
+
+```objective-c
+AFOAuthCredential *credential =
+        [AFOAuthCredential retrieveCredentialWithIdentifier:serviceProviderIdentifier];
+```
+
