+### Skipping the build step
+
+If you have already built your app binaries using [`patrol build`][patrol_build],
+you can skip the build step with `--no-build`:
+
+```
+patrol build android
+patrol test --no-build
+```
+
+This is useful in CI pipelines or iterative workflows where you want to build
+once and run tests multiple times without rebuilding. The previously built
+binaries are picked up from their default output paths.

+### Skipping the build step
+
+If you want to separate the build and test steps (e.g. to build once and run
+tests multiple times), you can use `patrol build` to pre-build and then
+`patrol test --no-build` to run with the existing binaries:
+
+```console
+$ patrol build android
+$ patrol test --no-build
+```
+
+The `--no-build` flag tells `patrol test` to skip the build step entirely and
+use the binaries previously produced by `patrol build android` (or
+`patrol build ios`). The binaries are expected at their default output paths.
