+**3. Testing Stage**
+
+This stage allows to run unit tests on each commit. To achieve that, add the following code to .gitlab-ci.yml file:
+
+```
+testing:
+  stage: test
+  script:
+    - xcodebuild -workspace MyWorkspace.xcworkspace -scheme MyScheme -configuration MyConfiguration -destination "platform=iOS Simulator,name=iPhone 7,OS=10.3" build test | xcpretty
+  except:
+    - triggers
+```
+
+Replace MyWorkspace, MyScheme and MyConfiguration with appropriate values. Also, make sure that simulator name and OS version are relevant.
+
+**4. Crashlytics Build Stage**
+
+This stage allows builds to be uploaded to Crashlytics automatically with each commit or merge to develop brach.
+*  Setup fastlane, if not yet done. To do that, run `fastlane init` in project's root folder and follow the steps.
+*  Create a line for Crashlytics build in `fastfile`. It should look like this:
+
+```
+lane :lane_name do
+        gym(scheme: "MyScheme", configuration: "MyConfiguration")
+        crashlytics(
+            api_token: "MyAPIToken",
+            build_secret: "MyBuildSecret",
+            debug: true,
+            groups: ["members"],
+            notifications: true,
+            notes: last_git_commit[:message]
+        )
+    end
+```
+
+Replace lane_name, MyScheme and MyConfiguration with appropriate values of your project. Replace MyAPIToken and MyBuildSecret from appropriate values from Crashlytics configuration.
+
+*  Test this line by invoking `fastlane ios lane_name.
+*  Add crashlytics stage to .gitlab-ci.yml. Don't forget to replace lane_name with your lane name:
+
+```
+crashlytics_build:
+  stage: crashlytics
+  script:
+    - fastlane ios lane_name
+  only:
+    - develop
+  except:
+  - triggers
+```
