I’m trying to play around with themes in order to understand how I can extend them. Numerous resources on the web tell that there should be some .ftl files contained with `themes` directory of the keycloak.

I’ve set up a docker container from [keycloak.org](http://keycloak.org), and `bash`ed into it. The directory is empty, there is only a README.md file in there. At the same time, there are 2 themes available in the keycloak and they are working.

I’ve tried searching for \*.ftl files inside of a container to no avail.

I’ve looked inside zipped distribution as well.

Any advice is appreciated 🙂

Docs for extending keycloak themes are here [Server Developer Guide](https://www.keycloak.org/docs/latest/server_development/index.html#_themes)

You can either create a jar file with your theme and put it in the docker container in `/opt/keycloak/providers/` or put an unpacked version in the `/opt/keycloak/themes/` dir.

I created a template for building a custom theme here [GitHub - p2-inc/keycloak-theme-template: Starter for building a Keycloak theme](https://github.com/p2-inc/keycloak-theme-template)
