+## Fuzzing
+
+To run fuzzing tests use the following command:
+
+```shell
+$ make fuzz
+```
+
+This command will install dependencies for the fuzzing process and run existing fuzzing tests.
+
+You can also use the following arguments:
+
+```
+FUZZ_TIMEOUT - time to run each fuzzing test (default 30) 
+FUZZ_FUNCTIONS - fuzzing tests that will be started (default "all")
+FUZZ_AUX - additional parameters for the fuzzer (for example, "-debug")
+FUZZ_NGFUZZ_DIR - path to ngfuzz tool
