To get started with developing add-ons, we first need access to where Home Assistant looks for local add-ons. For this you can use the Samba or the SSH add-ons. For Samba, once you have enabled and started it, your Home Assistant instance will show up in your local network tab and share a folder called "addons". This is the folder to store your custom add-ons. For SSH, you will have to install it. Before you can start it, you will have to have a private/public key pair and store your public key in the add-on config (see docs for more info). Once started, you can SSH to Home Assistant and store your custom add-ons in the /addons directory.
