 Experimental, minimalistic, `no_std` friendly abstract virtual machine for CosmWasm contracts execution.
 
+Based on `wasmi` interpeter and can be run in other VM. Allows to host CosmWasm VM inside other Wasm VM. 
+In contrast, Cosmos `wasmd` VM can run only on native host.
+
+[Specification](SPEC.md)
+
 ### Getting started
 
-- [Install Nix](https://zero-to-nix.com/start/install)
-- Enter the dev env with: `nix develop`
+- [Install Nix](https://zero-to-nix.com/start/install) and enter the dev env with: `nix develop`.
+- Or install latest Rust nightly. 
 - Run test suite using: `cargo test`
 
+### Research
+
+Install `flamegraph` (in nix shell already installed)
+
+`RUST_LOG=trace cargo run --bin research --release 2>&1 | tee research.log` and see some output for deep logging.
+
+`RUST_LOG=info cargo run --bin research --release` and see some output long run with coarse grain output.
+
+`flamegraph target/release/research`
+
+Modify `research.rs` as needed.
