+## Copr RPM builds
+
+### From a pull request
+
+The [.packit.yaml](.packit.yaml) tells [Packit](https://packit.dev) to build RPMs from
+pull requests in Copr. RPMs from each PR are in a separate repository which you can enable
+to install the RPM.
+
+For example, for [PR#43](https://github.com/fedora-ci/mini-tps/pull/43)
+the repository is [packit/fedora-ci-mini-tps-43](https://copr.fedorainfracloud.org/coprs/packit/fedora-ci-mini-tps-43/) (might be already deleted).
+You can either run `dnf copr enable packit/fedora-ci-mini-tps-43 ` or if you need a URL to the
+repo file then you can find it in the `Repo Download` on the Copr page.
+
+### From the main branch
+
+Currently, we don't build automatically because there are no tests and
+an unnoticed push to `main` could silently break our RHEL/Fedora pipelines.
+To create a new build:
+
+- run `rpmdev-bumpspec mini-tps.spec` to bump the release in the spec file
+- run `packit srpm --no-update-release` to create a SRPM
+- Go to [@osci/mini-tps New Build](https://copr.fedorainfracloud.org/coprs/g/osci/mini-tps/add_build_upload),
+  select the SRPM file and hit `Build`
+
+To enable the automatic builds, all you need to do is uncomment the `copr_build` job
+in the [.packit.yaml](.packit.yaml).
+
+## Testing your change in a Jenkins pipeline
+
+Mini-TPS is used in the installability pipeline in Fedora and RHEL. The way you can test a
+change from a (yet unmerged) pull request in those pipelines:
+
+#### Fedora
+
+- Replace `dnf -y copr enable @osci/mini-tps` with `dnf -y copr enable packit/fedora-ci-mini-tps-<PR-number>`
+  in [prepare.sh](https://github.com/fedora-ci/installability-pipeline/blob/master/prepare.sh#L13)
+  and open a PR in the [repo](https://github.com/fedora-ci/installability-pipeline).
+- Once the PR appears in [pipelines for PRs](https://osci-jenkins-1.ci.fedoraproject.org/job/fedora-ci/job/installability-pipeline/view/change-requests/), submit `Build with Parameters`.
+
+#### RHEL
+
+- Replace [repo url](https://gitlab.cee.redhat.com/osci-pipelines/installability-pipeline/-/blob/master/prepare.sh?ref_type=heads#L27)
+  with `https://copr.fedorainfracloud.org/coprs/packit/fedora-ci-mini-tps-<PR-number>/repo/epel-${RHEL_VER_MAJOR}/packit-fedora-ci-mini-tps-<PR-number>.repo` and open an MR in the
+  [repo](https://gitlab.cee.redhat.com/osci-pipelines/installability-pipeline).
+- Once the MR appears in [pipelines for MRs](https://jenkins.prod.osci.redhat.com/job/OSCI-Pipelines/job/osci-pipelines%252Finstallability-pipeline/view/change-requests/),
+  submit `Build with Parameters`.
