* Copies of repositories on your machine are called clones. If you need help cloning to your local environment you can learn how from the GitHub documentation on [cloning a repository](https://docs.github.com/en/github/creating-cloning-and-archiving-repositories/cloning-a-repository-from-github/cloning-a-repository).
2. Before you start working on any execises, you should first ensure you have the following installed:
* **NPM**. You should have installed NPM already in our [Installing Node.js](https://www.theodinproject.com/lessons/foundations-installing-node-js) lesson. Just in case you need to check, type `npm --version` in your terminal. If you get back `Command 'npm' not found, but can be installed with:`, **do not follow the instructions in the terminal** to install with `apt-get` as this causes permission issues. Instead, go back to the installation lesson and install Node with NVM by following the instructions there.
* **Jest**. After cloning this repository to your local machine and installing NPM, go into the newly created directory (`cd javascript-exercises`) and run `npm install`. This will install Jest and set up the testing platform based on our preconfigured settings.
* **Jest**. After cloning this repository to your local machine and installing NPM, go into the newly created directory (`cd javascript-exercises`) and run `npm install`. This will install Jest and set up the testing platform based on our preconfigured settings. Your NPM may warn you of vulnerabilities within the NPM Packages: `6 vulnerabilities (1 moderate, 2 high, 3 critical)`. You can resolve this by running `npm audit fix`.
3. Each exercise includes 3 files: a markdown file with a description of the task, an empty (or mostly empty) JavaScript file, and a set of tests. To complete an exercise, you'll need to go to the exercise directory with `cd exerciseName` in the terminal and run `npm test exerciseName.spec.js`. This should run the test file and show you the output.
* When you first run a test, it will fail. This is by design! You must open the exercise file and write the code needed to get the test to pass.
4. Some of the exercises have test conditions defined in their spec file as `test.skip` compared to `test`. This is purposeful. After you pass one `test`, you will change the next `test.skip` to `test` and test your code again. You'll do this until all conditions are satisfied. **All tests must pass at the same time**, and you should not have any `test.skip` instances by the time you finish an exercise.
