 Installing RPM packages directly from a `http(s)` url that points to the RPM file is also supported, you can just put the URLs under `install:` and they'll be installed along with the other packages. The magic string `%OS_VERSION%` is substituted with the current VERSION_ID (major Fedora version) like with the `repos:` property.
 
-The module can also replace base RPM packages. Under `replace:`, the module finds every pair of keys `- from-repo:` and `packages:`. (Multiple pairs are supported.) The module downloads the repository file declared by `- from-repo:` into `/etc/yum.repos.d/` and from that repository replaces packages declared under `packages:` using the command `rpm-ostree override replace`. The repository file is then deleted. The magic string `%OS_VERSION%` is substituted with the current VERSION_ID (major Fedora version) as already said above.
+The module can also replace base RPM packages with packages from COPR repo. Under `replace:`, the module finds every pair of keys `- from-repo:` and `packages:`. (Multiple pairs are supported.) The module downloads the COPR repository file declared by `- from-repo:` into `/etc/yum.repos.d/`, and from that repository replaces packages declared under `packages:` using the command `rpm-ostree override replace`. The COPR repository file is then deleted. The magic string `%OS_VERSION%` is substituted with the current VERSION_ID (major Fedora version) as already said above. At the moment, only COPR repo is supported.
 
 :::note
 [Removed packages are still present in the underlying ostree repository](https://coreos.github.io/rpm-ostree/administrator-handbook/#removing-a-base-package), what `remove` does is kind of like hiding them from the system, it doesn't free up storage space.
