-- [AMWA BCP-003](https://github.com/AMWA-TV/nmos-api-security) Best Practices for NMOS API Security
-
-Readers should then read the [documentation](docs/) in this repository, and the [APIs](APIs/), which are written in RAML -- if a suitable tool is not available for reading this, then [this](APIs/generateHTML) will create HTML versions.
