+# OSS-Fuzz integration
+
+The fuzzers in this folder are used for our [OSS-Fuzz](https://github.com/google/oss-fuzz)
+integration.
+
+To run this, you can follow the steps:
+
+```sh
+git clone https://github.com/google/oss-fuzz
+cd oss-fuzz
+python3 infra/helper.py build_fuzzers pacemaker
+python3 infra/helper.py run_fuzzer pacmaker utils_fuzzer
+```
+
+
+## OSS-Fuzz logic
+
+The corresponding logic for Pacemaker on OSS-Fuzz can be found [here](https://github.com/google/oss-fuzz/tree/master/projects/pacemaker)
