-<h1>Create a component harness</h1>
+# Harness Creation
 
 > Author: Thomas Laforge
 
-### Information
+### Run Application
 
-The goal of this challenge is to create a test harness for `slider.component.ts`. The harness file, `slider.harness.ts`, has already been created.
-
-The following API needs to be implemented:
-
-```ts
-  async clickPlus(): Promise<void> ;
-
-  async clickMinus(): Promise<void>;
-
-  async getValue(): Promise<number> ;
-
-  async getMinValue(): Promise<number>;
-
-  async disabled(): Promise<boolean>;
-
-  async setValue(value: number): Promise<void>;
+```bash
+npx nx serve create-harness
 ```
 
-Additionally, you should create a `HarnessPredicate` with the default predicate and the `minValue` property.
+### Documentation and Instruction
 
-```ts
-  static with<T extends MySliderHarness>(
-    this: ComponentHarnessConstructor<T>,
-    options: SliderHarnessFilters = {}
-  ): HarnessPredicate<T>;
-```
-
-Lastly, you will need to create the test suite for `app.component`. Some default tests have already been written, but feel free to add as many tests as you want and create as many harness methods as you need.
