+
+Installation
+============
+
+Step 1: Install Context
+----------------------------------
+Open a command console, enter your project directory and execute:
+
+```console
+$ composer require --dev macpaw/behat-http-mock-context
+```
+
+Step 2: Update Container config to load Context
+----------------------------------
+In the `config/services_test.yaml` file of your project:
+
+```yaml
+    BehatHttpMockContext\:
+        resource: '../vendor/macpaw/behat-http-mock-context/src/*'
+        arguments:
+            - '@test.service_container'
+            
+    BehatHttpMockContext\Collection\ExtendedMockHttpClientCollection:
+        arguments:
+            - !tagged_iterator mock.http_client
+```
+
+Step 2: Mock http 
+=============
+Example you have http client in `config/services.yaml`
+```yaml
+    oauth_http_client:
+        class: Symfony\Contracts\HttpClient\HttpClientInterface
+        factory: ['Symfony\Component\HttpClient\HttpClient', createForBaseUri]
+        arguments:
+            - '%env(OAUTH_URL)%'
+```
+
+Now you need mock this client in `config/services_test.yaml`
+
+```yaml
+    BehatHttpMockContext\Collection\ExtendedMockHttpClientCollection:
+        arguments:
+            - !tagged_iterator mock.http_client
+
+    oauth_http_client:
+        class: ExtendedMockHttpClient\ExtendedMockHttpClient
+        arguments:
+            - '%env(OAUTH_URL)%'
+        tags: ['mock.http_client']
+...
+```
+
+Step 4: Configure Behat
+=============
+Go to `behat.yml`
+
+```yaml
+...
+  contexts:
+    - BehatHttpMockContext\Context\MockContext
+...
+```
