 ## Quickstart
+DetectionLab now contains build scripts for \*NIX and MacOS users!
+
+There are two build scripts:
+- `build.sh` - Builds the entire lab from scratch. Takes 3-5 hours depending on hardware resources and bandwidth
+- `build_vagrant_only.sh` - Downloads pre-built Packer boxes from S3 and builds the lab from those boxes. This option is recommended if you have more bandwidth than time.
+
+---
+
+## Building from Scratch
 1. Determine which Vagrant provider you want to use.
   * Note: Virtualbox is free, the [VMWare vagrant plugin](https://www.vagrantup.com/vmware/#buy-now) is $80.
+
+  **NOTE:** If you have more bandwidth than time, you can skip the building of the Packer boxes and download the boxes directly from S3 and put them into the `Boxes` directory:
+
+Provider | Box  | URL | MD5 | Size
+------------|-----|-----|----|----
+Virtualbox |Windows 2016 | https://s3-us-west-1.amazonaws.com/detectionlab/windows_2016_virtualbox.box | 614f984c82b51471b5bb753940b59d38 | 6.4GB
+Virtualbox | Windows 10 | https://s3-us-west-1.amazonaws.com/detectionlab/windows_10_virtualbox.box | 30b06e30b36b02ccf1dc5c04017654aa | 5.8GB
+VMware | Windows 2016 | https://s3-us-west-1.amazonaws.com/detectionlab/windows_2016_vmware.box | 1511b9dc942c69c2cc5a8dc471fa8865 | 6.7GB

+
+If you choose to download the boxes, you may skip steps 2 and 3. If you don't trust pre-built boxes, I recommend following steps 2 and 3 to build them on your machine.
+
+
 2. `cd` to the Packer directory and build the Windows 10 and Windows Server 2016 boxes using the commands below. Each build will take about 1 hour. As far as I know, you can only build one box at a time.
