+### How do I manually configure the Cocoapods Podfile?
+
+The plugin will try to automatically update the Cocoapods Podfile but that may fail if
+the Podfile is too complex. In that situation, you can manually configure the pod method.
+
+```gradle
+// File: shared/build.gradle
+j2objcConfig {
+    xcodeTargetsManualConfig true
+    ...
+}
+```
+
+The "pod method" definition will still be added automatically (e.g.
+`def j2objc_shared...`). However, the "pod method" will not be added to any
+targets, so that needs to be done manually. See example of the Podfile below:
+
+```
+// File: ios/Podfile
+...
+
+# J2ObjC Gradle Plugin - PodMethods - DO NOT MODIFY START - can be moved as a block
+def j2objc_shared
+    pod 'j2objc-shared-debug', :configuration => ['Debug'], :path => '../shared/build/j2objcOutputs'
+    pod 'j2objc-shared-release', :configuration => ['Release'], :path => '../shared/build/j2objcOutputs'
+end
+# J2ObjC Gradle Plugin - PodMethods - DO NOT MODIFY END
+
+<SOME COMPLEX RUBY>
+    ...
+    # NOTE: this line must be added manually for the relevant targets:
+    j2objc_shared
+    ...
+end
+```
+
+To disable all modifications of the Podfile, disable the `j2objcXcode` task.
+This will also skip the `pod install` step. The podspec files will still
+be written (done by the `j2objcPodspec` task).
+
+```gradle
+// File: shared/build.gradle
+j2objcConfig {
+    ...
+}
+j2objcXcode {
+    enabled = false
+}
+```

 ### How do I manually configure my Xcode project to use the translated libraries?
