 Custom mutators enhance and alter the mutation strategies of afl++.
 For further information and documentation on how to write your own, read [the docs](../docs/custom_mutators.md).
 
+## Examples
+
+The `./examples` folder contains examples for custom mutators in python and C.

+## Rust
+
+In `./rust`, you will find rust bindings, including a simple example in `./rust/example` and an example for structured fuzzing, based on lain, in`./rust/example_lain`.
