+### Cleanup
+
+To remove DAQIRI's container image or bare-metal install without touching the build prerequisites (DPDK, DOCA libraries, CUDA, hugepages, NIC drivers), use [`scripts/cleanup.sh`](https://github.com/NVIDIA/daqiri/blob/main/scripts/cleanup.sh):
+
+=== "Container"
+
+    ```bash
+    scripts/cleanup.sh container             # interactive
+    scripts/cleanup.sh container --dry-run   # show what would be removed
+    ```
+
+    Override `IMAGE_TAG=` if you built with a non-default tag.
+
+=== "CMake build (bare-metal)"
+
+    ```bash
+    scripts/cleanup.sh cmake             # interactive, manifest-driven
+    scripts/cleanup.sh cmake --dry-run   # show what would be removed
+    scripts/cleanup.sh cmake --yes       # non-interactive
+    ```
+
+    See [Cleanup](tutorials/bare-metal-cmake-build.md#cleanup) in the bare-metal tutorial for manifest semantics, the `DAQIRI_PREFIX` override, and verification details.
+
+Pass `all` instead of `container` or `cmake` to remove both.

 ### Use an Installed Library
 
 After installation, CMake consumers can link against the exported target:

+## Cleanup
+
+To remove the CMake install while keeping every prerequisite (DPDK, DOCA libraries, CUDA, hugepages, NIC drivers) in place, run [`scripts/cleanup.sh`](https://github.com/NVIDIA/daqiri/blob/main/scripts/cleanup.sh) with the `cmake` target:
+
+```bash
+scripts/cleanup.sh cmake             # interactive, with manifest preview
+scripts/cleanup.sh cmake --dry-run   # show what would be removed
+scripts/cleanup.sh cmake --yes       # non-interactive
+```
+
+The script reads `build/install_manifest.txt` (written by [Step 5.2](#52-install)) for the canonical list of installed paths, then refuses to remove anything unless every manifest entry is under `DAQIRI_PREFIX`. Manifest entries that are already absent are reported and skipped so cleanup can be rerun after a partial removal; verification still runs and decides the final exit status. Override the install prefix with `DAQIRI_PREFIX=...` if you installed somewhere other than `/opt/daqiri`, or `BUILD_DIR=...` if your build tree is named something other than `build`. When the manifest is missing, the script falls back to a name-scoped scan that auto-removes only DAQIRI-owned artifacts and flags vendored `spdlog/`, `yaml-cpp/`, and `libyaml-cpp.so*` for manual review. The final step runs verification (`ls /opt/daqiri`, `pkg-config --modversion daqiri`, `ldconfig -p | grep daqiri`) and exits non-zero if any DAQIRI artifact is still present.
+
+Pass `all` instead of `cmake` to also remove the container image (`docker image rm "$IMAGE_TAG"`) in the same run.
