 Differential fuzzing for Neo (N3) blockchain virtual machine based on LibAFL
 
-## Status
+## Install
 
-IN DEVELOPMENT
+Clone repository:
 
-## Usage
+```sh
+git clone --recursive https://github.com/Slava0135/N3onDiff
+```
+
+Install dependencies:
 
-Install Rust (nightly) using `rustup`
+- neo-go
+  - make
+  - go 1.22+
+- neo
+  - dotnet-sdk 8.0
+  - aspnet-runtime 8.0
+- N3onDiff
+  - make
+  - rust 1.80+ (__nightly__)
+
+## Usage
 
 ```sh
-git clone --recursive https://github.com/Slava0135/N3onDiff
 make
-cargo run
+cargo run --release
 ```
+
+Scripts with issues (different output) will be put into `./crashes`.
+
+File names are base64 encoded scripts (using URL alphabet - __not valid for VM__!!!).
+
+Contents of these files are __NOT__ valid script bytes (they are used internally by LibAFL for serialization).
+
+Instead, find `*.metadata` files, where outputs for both VMs are saved and encoded base64 script can be found (and more info in the future).
+
+## Found issues
+
+In case you found new VM bugs using this fuzzer, __please__ make an issue and add the link here!
