 ## Option 1: Singularityware Vagrant Box
 
-We are maintaining a set of Vagrant Boxes via <a href="https://atlas.hashicorp.com/" target="_blank">Atlas</a>, one of <a href="https://www.hashicorp.com/#open-source-tools" target="_blank">Hashicorp</a> many tools that likely you've used and haven't known it. The <a href="https://atlas.hashicorp.com/singularityware/boxes/singularity-2.2.99" target="_blank">Singularity Box</a> is for version 2.2.99, and will be updated appropriately with the release of 2.3. To use this box, you can simply create a folder, and then do the following:

We currently have boxes for the following versions of Singularity:

+ - [singularityware/singularity-2.2.99](https://atlas.hashicorp.com/singularityware/boxes/singularity-2.2.99)
+ - [singularityware/singularity-2.3](https://atlas.hashicorp.com/singularityware/boxes/singularity-2.3)
 
 ```bash
 mkdir singularity-vm
 cd singularity-vm
-vagrant init singularityware/singularity-2.2.99
+vagrant init singularityware/singularity-2.3
+vagrant up
 vagrant ssh
 ```
 
+You are then ready to go with Singularity 2.3!
+
+```
+vagrant@vagrant:~$ which singularity
+/usr/local/bin/singularity
+vagrant@vagrant:~$ singularity --version
+2.3-master.gadf5259
+vagrant@vagrant:~$ singularity create test.img
+Initializing Singularity image subsystem
+Opening image file: test.img
+Creating 768MiB image
+Binding image to loop
+Creating file system within image
+Image is done: test.img
+```
+
+Note that when you do `vagrant up` you can also select the provider, if you use vagrant for multiple providers. For example:
+
+```
+vagrant up --provider virtualbox
+```
+
+although this isn't entirely necessary if you only have it configured for virtualbox.

 ## Option 2: Vagrant Box from Scratch
 
 If you want to use a different version of Singularity, or want to get more familiar with how Vagrant and VirtualBox work, you can build your own Vagrant Box from scratch.  In this case, we will use the Vagrantfile for `bento/ubuntu-16.04`, however you could also try any of the <a href="https://atlas.hashicorp.com/bento" target="_blank">other bento boxes</a> that are equally delicious. As before, you should first make a separate directory for your Vagrantfile, and then init a base image.
