Update microsite, move to mdoc (#1023)

We used to rely on `tut` for docs, however it is deprecated to be replaced with mdoc.

Moved to an `mdoc` folder structure and updated all of the links (what a pain).

+# Setup API Server
+The API Server is the main run-time for VinylDNS.  To setup the API server, follow these steps:
+
+1. [Pre-requisites](pre.html)
+1. [Setup AWS DynamoDB](setup-dynamodb.html)
+1. [Setup MySQL](setup-mysql.html)
+1. [Setup AWS SQS](setup-sqs.html)
+1. [Configure API Server](config-api.html)
+1. [Using the API Docker Image](#using-the-api-docker-image)
+
+## Using the API Docker Image
+The API server is provided via the [VinylDNS API Image](https://hub.docker.com/r/vinyldns/api/).
+The docker image allows you to mount your own config, as well as your own external dependency jars.
+
+The API server is _stateless_, allowing you to run multiple instances in multiple data centers for high-availability
+purposes.
+
+**Note: If using VinylDNS Java Crypto and the pre-requisites defined here, no additional jars need to be loaded.**
+
+## Environment variables
+1. `MYSQL_ADDRESS` - the IP address of the mysql server; defaults to `vinyldns-mysql` assuming a docker compose setup
+1. `MYSQL_PORT` - the port of the mysql server; defaults to 3306
+
+## Volume Mounts
+The API exposes volumes that allow the user to customize the runtime.  Those mounts include:
+
+* `/opt/docker/lib_extra` - place here additional jar files that need to be loaded into the classpath when the application starts up.
+This is used for "plugins" that are proprietary or not part of the standard build.  All jar files here will be placed on the class path.
+* `/opt/docker/conf` - place an `application.conf` file here with your own custom settings.  Once you have your config created,
+place here.
+
+## Ports
+The API only exposes port 9000 for HTTP access to all endpoints
