 # Installation
 
-## Docker
+Materia is configured to use Docker containers in production environments, orchestrated through docker compose, though other orchestration frameworks could potentially be used instead. While it may be possible to deploy Materia without Docker, we **do not recommend doing so**.
+
+## Docker Deployment
 
 We publish production ready docker and nginx containers in the [Materia Docker repository](https://github.com/orgs/ucfopen/packages/container/package/materia).  For more info on using Docker in Production, read the [Materia Docker Readme](docker/README.md)

 ## Git Hooks
 
-There is a pre-commit hook available to ensure your code follows our linting standards. Check out the comments contained inside the hook files (in the githooks directory) to install it, you'll need a few dependencies installed to get linting working.

+# Authentication
+
+Materia supports two forms of authentication:
+
+- Direct authentication through direct logins. Note that Materia does not provide an out-of-the-box tool for user generation. If your goal is to connect to an external identity management platform or service, you will need to author an authentication module to support this. Review FuelPHP's [Auth package and Login driver](https://fuelphp.com/docs/packages/auth/types/login.html) documentation, as well as the `ltiauth` and `materiaauth` packages located in `fuel/packages` to get started.
+- Authentication over LTI. This is the more out-of-the-box solution for user management and authentication. In fact, you can disable direct authentication altogether through the `BOOL_LTI_RESTRICT_LOGINS_TO_LAUNCHES` environment variable, making LTI authentication the only way to access Materia. Visit our [LTI Integration Overview](https://ucfopen.github.io/Materia-Docs/develop/lti-integrations.html) page on the docs site for more information.

+# Asset Storage
+
+Materia enables users to upload media assets for their widgets, including images and audio. There are two asset storage drivers available out of the box: `file` and `db`. `file` is the default asset storage driver, which can be explicitly set via the `ASSET_STORAGE_DRIVER` environment variable.
