 Some modules like ti.map or ti.facebook are included with the SDK. To update to the latest versions you have to edit the links in `support/module/packaged/modules.json` and run `node build/scons-modules-integrity.js`. This will download the files and update the integrity values.
 
+### Update Android libraries
+The `/android/titanium/build.gradle` file contains various Android libraries that are used in the SDK. If you want to update them check the corresponding release pages:
+* https://developer.android.com/jetpack/androidx/releases/recyclerview
+* https://developer.android.com/jetpack/androidx/releases/swiperefreshlayout
+* https://developer.android.com/jetpack/androidx/releases/camera
+* https://developer.android.com/jetpack/androidx/releases/transition
+* https://developer.android.com/jetpack/androidx/releases/vectordrawable
+* https://developer.android.com/jetpack/androidx/releases/viewpager
+* https://developer.android.com/jetpack/androidx/releases/cardview
+* https://developer.android.com/jetpack/androidx/releases/drawerlayout
+* https://developer.android.com/jetpack/androidx/releases/exifinterface
+* https://developer.android.com/jetpack/androidx/releases/media
+for a new version and change the number in the build.gradle file. Some version numbers are managed inside `/android/templates/build/ti.constants.gradle`. After that build the SDK and run `npm run test` to see if everything is still running. Building Kitchensink, Hyperloop-examples and a custom app is also helpful. 
+
+### Documentation
+
+If you want to help updating and improving the documentation you can checkout the repository and edit the files in `/apidoc/`. Those files are shown in the API documentation at https://titaniumsdk.com/api/ and include all methods, properties, examples and so on. After you made changes run `npm run lint:docs` to see if your changes produce a valid documentation. The PR commit title you create should start with `docs: ` and a proper title like: `docs: updated textfield examples`. 
+All other documentation files (e.g. the guides) are located in the https://github.com/tidev/titanium-docs repository. In case you want to update guides, tutorials or spelling mistakes you clone that repo and follow the README file inside the main folder.
