Alternatively, you can use the cd terminal command to do this. You can run the command pwd to check you have done this correctly.

2. Install the dependencies for the web app:

npm install

3. Create a copy of the sample environment variables files, .env.sample, either manually or by running the following command:

cp .env.sample .env.local

4. Add your OpenAI API key to the environment variables file .env.local and save the changes:

OPENAI_API_KEY=my-openai-api-key-1

5. Run the local development server:

npm run dev

6. Open your browser of choice and head to http://localhost:3000 to see the web app live locally.

7. Make desired changes to the web app. Next.js will automatically update the web app when you save changes to the source code.
