I think the main problem is that you are not using the appropriate devise installation method. Here are the right generators for developing documentation:

#this installs the devise initializer which is needed to run devise in r3. 
rails generate devise:install

#this generates your model as a devise resource
rails generate devise [MODEL_NAME]

#this copies all the view files into your local app for modifications
rails generate devise:views
