+
+Platform, support changes:

+  - x86 or x86_64
+- Miniconda
+  - python2 or python3
+  - x86 or x86_64

+  tests](spec/default_spec.rb#L100) and [kitchen tests](.kitchen.yml#L16) for
+  the full list.
+
+This also serves as an example for developing and testing Chef cookbooks. It
+uses:
+
+- [ChefDK](https://downloads.chef.io/chef-dk/); 0.8.1
+  - chef-client 12.4.4
+  - [Berkshelf](http://berkshelf.com) for dependency resolution; 3.3.0

-- [Berkshelf 3](http://berkshelf.com/) for dependency resolution
-- [Vagrant](https://www.vagrantup.com) for development
-- [Chefspec](https://github.com/sethvargo/chefspec) for rapid testing

-## Requirements
+- Vagrant
 
-This repo has only been tested with RVM; YMMV with other installation methods

+For the full experience (e.g. running the test suite), also install:
 
-- Berkshelf 3.1.3
-- Chefspec 4.0.0
-- Test Kitchen 1.2.1
-- Foodcritic 4.0.0
-- Vagrant 1.6+
+- ChefDK
   - [vagrant-omnibus](https://github.com/schisamo/vagrant-omnibus)
-  - [vagrant-berkshelf](https://github.com/berkshelf/vagrant-berkshelf): note
-    that `>= 2.0.1` is required
-
-It sounds like [Chef-DK](http://www.getchef.com/downloads/chef-dk/) is the new
-recommended installation path, but I have not had a good experience with it (as
-of *0.1.0-1*). Again, YMMV.

+- Docker
+  - Don't forget [Docker Machine](https://docs.docker.com/machine/) if you're
+    on OSX; installing this via homebrew is highly recommended.

-# it's sourced in /etc/profile.d
-$> vagrant ssh
-$vagrant> conda --version
-conda 3.10.0
-```
+  # the sample image includes `recipe[anaconda::shell_conveniences]`, which
+  # means conda is already in PATH via /etc/profile.d
+  $> vagrant ssh
+  $vagrant> conda --version
+  conda 3.14.1
 
-In addition, by default an IPython notebook server is enabled and started:
+  # or you add it to PATH manually
+  $> vagrant ssh
+  $vagrant> export PATH=/opt/anaconda/2.3.0/bin:${PATH}
+  $vagrant> conda --version
