+# windows-plugin-authenticator
+
+This is an internal crate that's meant to be a safe abstraction layer over the generated Rust bindings for the Windows WebAuthn Plugin Authenticator API's.

+You can find more information about the Windows WebAuthn API's [here](https://github.com/microsoft/webauthn).
+
+## Building

+
+- `LIBCLANG_PATH` -> the path to the `bin` directory of your LLVM install ([more info](https://rust-lang.github.io/rust-bindgen/requirements.html?highlight=libclang_path#installing-clang))
+
+### Bash Example
+
+```
+export LIBCLANG_PATH='C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm\x64\bin'
+```
+
+### PowerShell Example
