## Usage
-The Aeneas binary is in `bin`; you can run: `./bin/aeneas.exe [OPTIONS] LLBC_FILE`,
+The Aeneas binary is in `bin`; you can run: `./bin/aeneas -backend {fstar|coq|lean|hol4} [OPTIONS] LLBC_FILE`,
where `LLBC_FILE` is an .llbc file generated by Charon.
Aeneas provides a lot of flags and options to tweak its behaviour: you can use `--help`
to display a detailed documentation.
+### Additional Steps for Lean Backend
+
+Files generated by the Lean backend import the `Base` package from Aeneas.
+To use those files in Lean, create a new Lean package using `lake new`,
+overwrite the `lean-toolchain` with the one inside `./backends/lean`,
+and add `Base` as a dependency in the `lakefile.lean`:
+```
+require Base from "PATH_TO_AENEAS_REPO/backends/lean"
+```
