 3. Make sure the build has finished before committing. If you made changes to the documentation, properties, methods, or anything else that requires an update to a generate file, this needs to be committed.
 4. After the changes have been pushed, publish the branch and [create a pull request](#creating-a-pull-request).
 
+### Angular, React, and Vue
+
+#### Modifying Files
+
+1. Locate the files inside the relevant root directory:
+  - Angular: `/angular/src`
+  - React: `/packages/react/src`
+  - Vue: `/packages/vue/src`
+2. Make your changes to the files. If the change is overly complex or out of the ordinary, add comments so we can understand the changes.
+3. Run lint on the directory and make sure there are no errors.
+4. Build the project.
+5. After the build is finished, commit the changes. Please follow the [commit message format](#commit-message-format) for every commit.
+6. [Submit a Pull Request](#submit-pull-request) of your changes.
+
+
+
+#### Preview Changes
+
+1. Run `npm run start` inside of the relevant test app directory. This will sync your previously built changes into a test Ionic app:
+  - Angular: `/angular/test-app`
+  - React: `/packages/react/test-app`
+  - Vue: `/packages/vue/test-app`
+2. In a browser, navigate to the page you wish to test.
+3. Alternatively, create a new page if you need to test something that is not already there.
+
+
+#### Lint changes
+
+1. Run `npm run lint` to lint the TypeScript in the relevant directory:
+  - Angular: `/angular/src`
+  - React: `/packages/react/src`
+  - Vue: `/packages/vue/src`
+2. If there are lint errors, run `npm run lint.fix` to automatically fix any errors. Repeat step 1 to ensure the errors have been fixed, and manually fix them if not.
+
+#### Modifying Tests
+
+1. Locate the test to modify inside the relevant test app directory:
+  - Angular: `/angular/test-app/e2e/src`
+  - React: `/packages/react/test-app/cypress/integration`
+  - Vue: `/packages/vue/test-app/tests/e2e`
+2. If a test exists, modify the test by adding an example to reproduce the problem fixed or feature added.
+3. If a new test is needed, copy an existing test, rename it, and edit the content in the test file.
+4. Run `npm run test` to run your tests.
+
+#### Building Changes
+
+1. Once all changes have been made, run `npm run build` inside of the root directory. This will add your changes to any auto-generated files, if necessary.
+2. Review the changes and, if everything looks correct, [commit](#commit-message-format) the changes.
+3. Make sure the build has finished before committing. If you made changes to the documentation, properties, methods, or anything else that requires an update to a generate file, this needs to be committed.
+4. After the changes have been pushed, publish the branch and [create a pull request](#creating-a-pull-request).
