+## Build Wheel
+
+The `clvm_rs` wheel has python bindings for the rust implementation of clvm.
+
+Use `maturin` to build the python interface. First, install into current virtualenv with
+
+```
+$ pip install maturin
+```
+
+While in the `wheel` directory, build `clvm_rs` into the current virtualenv with
+
+```
+$ maturin develop --release
+```
+
+On UNIX-based platforms, you may get a speed boost on `sha256` operations by building
+with OpenSSL.
+
+```
+$ maturin develop --release --features=openssl
+```
+
+To build the wheel, do
+
+```
+$ maturin build --release
+```
+
+or
+
+```
+$ maturin build --release --features=openssl
+```
