 3. Re-deploy the module with `gradlew clean deploy`.
 
 An example of this can be seen in [this](https://github.com/liferay/liferay-portal/commit/5b2ae3732d96f7f0dec6d35cb4de99f9d389c248) commit (look at the [`package.json`](https://github.com/liferay/liferay-portal/blob/5b2ae3732d96f7f0dec6d35cb4de99f9d389c248/modules/apps/frontend-editor/frontend-editor-ckeditor-web/package.json) file)

+## Patching
+
+- Make sure you're update to date with the [superproject](https://github.com/liferay/liferay-ckeditor) repository:
+
+	```sh
+	git pull origin master
+	```
+
+- Set up everything to start working on a patch:
+
+	```sh
+	sh ck.sh setup
+	```
+
+- Work on your changes:
+
+	`cd` into the `ckeditor-dev/` submodule and prepare your desired changes on the `liferay` branch.
+
+	This could be `cherry-pick`ing a previously created commit or manually editing a file, so this can't be automated.
+
+- Create your commit, add your changes and write a good commit message.
+
+- Navigate back to the superproject's root directory and create the patch:
+
+	```sh
+	cd ..
+	sh ck.sh patch
+	```
+
+- Create a build of CKEditor containing the patches:
+
+	From the root of the superproject's directory, run
+
+	```sh
+	sh ck.sh build
+	```
+
+- Don't forget to add the changes and commit
