Hello,

In case that you are using Git and GitHub for your project, you could make the changes directly to your GitHub project and then pull them to your Droplet. If your project uses Git and if you are not familiar with it, you could learn more about it here:

https://www.digitalocean.com/community/cheatsheets/how-to-use-git-a-reference-guide

If you are not using Git, then you could change your files directly on your server. There are two ways to do so:

• Via SFTP:

https://docs.digitalocean.com/products/droplets/how-to/transfer-files/

• Or via the terminal over SSH:

Hope that this helps!
Regards,
Bobby
