+To build this devfile registry into a container image run `bash .ci/build.sh`. A container image will be built using the [devfile registry build tools](https://github.com/devfile/registry-support/tree/master/build-tools). By default these scripts will use `docker`, if you want to use `podman` you should first run `export USE_PODMAN=true` before executing the build script.
 
 From there, push the container image to a container registry of your choice and deploy using one of the methods outlined [here](https://github.com/devfile/registry-support#deploy).
