+## (Temporarily) reduce pipeline run time
+
+During work on MR you may want to reduce the pipeline run time to get feedback faster. You can change the pipeline by editing the `.gitlab-ci.yml` and `scripts/ci/jobs/*.yml` files. It is good practice to mark these changes with commits starting with `drop: ...` in the commit message so they can be removed later easily.
+
+### `.gitlab-ci.yml`
+
+These variables modify the pipeline:
+
+- `BUILD_TESTS`: Set this to `false` to disable unit tests.
+- `BUILD_CTEST`: Set this to `false` to disable ctest (benchmark) tests.
+- `CTEST_INCLUDE_REGEX`: Set this to a regex to select benchmarks to run, e.g. `nb` would select all notebook-based tests and would disable all other benchmarks.
+
+All jobs get included in the `include:`-section. You can simple comment out files to disable jobs defined in that files. Please note that some jobs depend on other jobs.
+
+### `scripts/ci/jobs/*.yml`
+
+All jobs are defined in these files. You can disable a single job by prefixing its name with a dot, e.g.:
+
+```yml
+# enabled job:
+build linux arch:
+
+# disabled job:
+.build linux arch:
+```
