+### Nix
+
+srcdump can be built or run with Nix flakes. The package puts nixpkgs' uv on `PATH`, and srcdump provisions angr with it on first run.
+
+```
+$ nix run github:angr/srcdump -- ./program
+$ nix develop    # shell with the Rust toolchain and uv
+```
+
 ## How it works
 
 srcdump is a thin orchestrator written in Rust.
