Currently, the official catalogue of Coop-Cloud apps is at [App catalogue]( https://docs.coopcloud.tech/apps/). There's an experimental version of the catalogue in the works; you can see the link to it in the image.
1. Assuming you have previously copied basic HTML5 code into the clipboard, you can right-click the top of the Linux command window, slide down to Edit, slide over to Paste and click on it.
1. Create the custom html app on your Capsul using Abra. The app is associated with the server named *coolstuff.ninja*. It will be listening at the domain name *coolstuff.ninja*, that is, after it is deployed, when you type https://coolstuff.ninja, you will see the minimal html5 page we've just saved in index.html. The --app-name option tells Abra to name the app *custom-html-ninj*.
This opens custom-html-ninj's configuration in a text editor, and you could update any values which need to be updated. In this case, everything looks good, so we don't make any changes.
1. It's time to deploy the app. It's a very basic app, and so the command line to deploy it is very simple. Type 'y' to confirm the deployment. After a few moments, you should see *SUCCESS: Yay! App should be available at **domain-name***.
You need to copy the index.html file into the custom-html-ninj app.
