+If you want to package a Rust package to conda-forge, you can use this recipe template:
+
+```yaml

+  version: "0.1.0"
+
+package:
+  name: ${{ name|lower }}
+  version: ${{ version }}

+        - cargo auditable install --locked --no-track --bins --root "$PREFIX" --path .
+      else:

+
+This recipe template supports different features:
+
+- `CARGO_PROFILE_RELEASE_STRIP=symbols` in order to reduce the size of the package by removing unnecessary symbols.
+- `CARGO_PROFILE_RELEASE_LTO=fat` in order to optimize the binary for better performance.
+- `cargo auditable install` in order to ensure the package is auditable.
+- Bundle licenses of statically linked libraries.
+- Use `--no-track` to not create `$PREFIX/.crates.toml` and `$PREFIX/.crates2.json`.
