WHAT'S STOPPINGDEVELOPERS?

NEW PATTERNS

SOLUTIONS

LOWER THE LEARNING CURVE

SIMPLE INSTALL WIKI

TRIM THE VOCABULARY

Focus on basic parts of cookbooks

RecipesTemplatesAttributes

Hide the rest

FRIENDLY SHELL WRAPPERS

USE A FAMILIARCOMMAND WRAPPER

( Make, rake, fab )

USE FAMILIAR SYNTAX

Javanode .my_cookbook.my_attribute

Rubynode[:my_cookbook][:my_attribute]

Pythonnode['my_cookbook']['my_attribute']

PROVIDE HIGH LEVEL API'S

BE OPINIONATEDMake decisions for them

...because they don't know
