 2 | 
 3 | [![Remix on Glitch](https://cdn.glitch.com/2703baf2-b643-4da7-ab91-7ee2a2d00b5b%2Fremix-button.svg)](https://glitch.com/edit/#!/import/github/gitdagray/node_api_key_relay)
 4 | 
 5 | **Start by clicking the Remix on Glitch button above.**
 6 | 
 7 | [YouTube Tutorial](https://youtu.be/uk9pviyvrtg) for this repository.
 8 | 
 9 | Add your API Keys to the .env file you will find on Glitch after launching this code by using the button above.
10 | 
11 | Modify the code in your Glitch project to add your own custom API endpoints.
12 | 
13 | You can host this NodeJS project elsewhere, but Glitch makes it easy.
14 | 
15 | Never include your .env file in a GitHub repository. Add _.env_ to your _.gitignore_ file before pushing a project to GitHub.
