 Your fuzz targets will be run on a [Google Compute Engine](https://cloud.google.com/compute/) VM (Linux) with some security restrictions.
 
+## Dependencies
+
+You should not make any assumptions on the availability of dependent packages 
+and libraries in the execution environment. Make sure to statically link any
+library dependencies with your fuzz target executable during build time 
+([example](https://github.com/google/oss-fuzz/blob/master/projects/tor/build.sh#L40)). 
+All build artifacts needed during fuzz target execution should be inside `$OUT` 
+directory, and other directories like `$WORK`, `$SRC`, etc will not be accessible. 
+You can ensure that the fuzz target works correctly by using `run_fuzzer` command 
+(see instructions [here](docs/new_project_guide.md#testing-locally)).
