+### Configured jobs
+
+The following jobs are currently configured in [jenkins/jobs.git](https://gitweb.torproject.org/project/jenkins/jobs.git/):
+
+ * [hugo-website.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/hugo-website.yaml) - builds websites with [Hugo](https://gohugo.io/) and
+   publishes them to the static mirror system. jobs based on this
+   template:
+   * hugo-website-research: builds <https://research.torproject.org/>
+   * hugo-website-status: builds <https://status.torproject.org/> (see
+     also [the status service](service/status)
+ * [lektor-website.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/lektor-website.yaml) - builds websites with [Lektor](https://www.getlektor.com/) and
+   publishes them to the static mirror system. jobs based on this
+   template:
+   * lektor-website-community: <https://community.torproject.org>
+   * lektor-website-donate: <https://donate.torproject.org>
+   * lektor-website-gettor: <https://gettor.torproject.org>
+   * lektor-website-newsletter: <https://newsletter.torproject.org>
+   * lektor-website-styleguide: <https://styleguide.torproject.org>
+   * lektor-website-support: <https://support.torproject.org>
+   * lektor-website-torbrowser-manual: <https://tb-manual.torproject.org>
+   * lektor-website-www: <https://www.torproject.org>
+   * lektor-website-dev: code for the future developer portal
+   * lektor-website-translation: this one is pecular and holds
+     translations for the above websites, one branch per project,
+     according to [the git repo](https://gitweb.torproject.org/translation.git/)
+ * [onionperf-docs.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/onionperf-docs.yaml): builds the [onionperf](https://gitweb.torproject.org/onionperf.git) documentation
+   using [Sphinx](https://www.sphinx-doc.org/) and publishes them to the static mirror system
+ * [stem.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/stem.yaml): builds <https://stem.torproject.org/> and pushes to
+   static
+ * [tor-extra-libs-windows.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/tor-extra-libs-windows.yaml): TBD
+ * [tor.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/tor.yaml): lots of jobs for the [core tor repository](https://gitweb.torproject.org/tor.git),
+   notably builds:
+   * `tor-ci-linux-$version-$variant`: various CI jobs (hardening,
+     rust, basic CI, clang, fuzzing, windows, mingw, etc)
+   * nightly debian package builds, shipped to
+     <https://deb.torproject.org>
+   * doxygen docs at <https://src-ref.docs.torproject.org>
+ * [torsocks.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/torsocks.yaml): runs CI for tor socks
+ * [website.yaml](https://gitweb.torproject.org/project/jenkins/jobs.git/tree/website.yaml): old WebWML website build, deprecated
+
+### Users
+
+From the above list, we can tentatively conclude the following teams
+are actively using Jenkins:
+
+ * **web team**: virtually all websites are built in Jenkins, and heavily
+   depend on the static site mirror for proper performance
+ * **network team**: the core tor project is also a heavy user of
+   Jenkins, mostly to run tests and checks, but also producing some
+   artefacts (Debian packages and documentation)
+ * **TPA**: uses Jenkins to build the status website
+ * **metrics team**: onionperf's documentation is built in Jenkins
