1. Clone the repository: git clone https://github.com/AlcaDesign/Twitch-AuthServer-Example.git.
2. Create the file "config.json" based on the /config/config.default.json.
   1. Create or edit a Twitch app that will redirect to http://127.0.0.1:3000/auth/twitch/callback.
   2. Insert the generated client ID and client secret into their respective fields.
   3. Change the scope as needed.
   4. Create a random key to put in session.secret (a phrase or just random bits if you'd prefer).
3. Run the npm install command in the repository folder to install the node dependencies.
4. Run the server: node index.js.
5. Open to this page in your browser: http://127.0.0.1:3000/.
6. Click "Login" and authorize your app with your credentials.
7. Once you're redirected, you should be back to the first page and your name should have appeared.
