+# Buttons and Counter
+
+This app currently features a button that increments a counter.
+
+## Task for Person A
+
+Create and switch to a new branch named `split-app-components`:
+
+```
+git switch -c split-app-components
+```
+
+### Task
+
+Split the `header`, `main` into separate components from `app.js`.
+
+- Separate the components into new functions that live in their own files.
+- Make sure to use those functions in `app.js` so the end result remains the same, and tests still run.
+- Remember - tests are your friend, run them before, during and after you've wrote some code. Use them to guide you.
+
+### Tests
+
+There are three tests that are _not_ skipped (lines 18 - 36 in `app.test.js`), use these tests to check your changes still let the app function as expected.
+
+### Result
+
+- You should end up with an `app.js` file, a `header.js` file, and a `main.js` file in your `src` directory.
+- All tests should pass.
+
+## Task for Person B
+
+Create and switch to a new branch named `add-decrement-button`:
+
+```
+git switch -c add-decrement-button
+```
+
+### Task
+
+Implement a decrement button.
+
+- Read the skipped tests (lines 38-53 in `app.test.js`) before you start. You will use these tests to guide you.
+- Write your code in `app.js`
+- Update the description of the app in the `header` element.
+
+### Tests
+
+Tests (lines 38-53 in `app.test.js`) are pre-written but skipped, un-skip them and run the tests before, during and after you write your code.
+
+### Result
+
+Your `app.js` file will now contain a button that decrements the counter and all the tests will run and pass.
