+# [pip](https://pip.pypa.io/)

+Compatible with probably any type of linux guest distro, will hook into pip's
+http and wheels cache directory under `$HOME/.cache/pip/http` and `$HOME/.cache/pip/wheels` as
+the default SSH user (usually `vagrant`) on your guest.
+
+To manually enable it:
+
+```ruby
+Vagrant.configure("2") do |config|
+  config.vm.box = 'some-box-with-pip-installed'
+  config.cache.enable :pip
+end
+```
