-SCAN statistical model checker
+# SCAN
+
+SCAN (StatistiCal ANalyzer) is a statistical model checker
+designed to verify large concurrent systems
+that defy classic verification techniques.
+
+## Developement status
+
+SCAN is currently in developement at DIBRIS, University of Genoa (UniGe)
+in the context of the [CONVINCE project](https://convince-project.eu/).
+There is no released version yet.
+
+## Formalism
+
+SCAN uses Channel Systems (CS) as models,
+and Metric Temporal Logic (MTL) as property specification language.
+
+## Modeling specification languages
+
+SCAN is being developed to accept models specified in multiple, rich modeling languages.
+At the moment the following languages are planned or implemented:
+
+- [x] State Charts specified in SCXML format.
+- [ ] Promela
+- [ ] JANI
+
+## Build instructions
+
+Currently, the only way to use SCAN is to build it from sources.
+
+### Install a Rust toolchain.
+
+The easiest and recommended way is to do so by installing [Rustup](https://rustup.rs/)
+either following the instructions on its homepage or through your OS's package manager.
+
+### Clone and compile
+
+Clone the repo and enter its root folder.
+From there, compile SCAN with
+
+```
+$ cargo build --release
+```
+
+(without the `--release` flag, the compiler will build in debug mode).
+
+Then, run SCAN with either
+
+```
+$ cargo run --release -- --help
+```
+
+or
+
+
+```
+$ target/release/scan --help
+```
+
+and the CLI help will show the available functionalities and commands' syntax.
