+### Step 2: (Experimental) Integrate CocoaPods dependendcies
+
+To integrate CocoaPods dependencies into the Bazel workspace, you must convert
+them into Bazel packages as described in [Converting CocoaPods dependencies](migrate-cocoapods.md).

+**Note:** CocoaPods conversion is a manual process with many variables.CocoaPods
+integration with Bazel has not been fully verified and is not officially

+
+### Step 3: Create a `BUILD` file
Once you have defined the workspace and external dependencies, you need to
create a `BUILD` file that tells Bazel how the project is structured. Create
the `BUILD` file at the root of the Bazel workspace and configure it to do an
initial build of the project as follows:
