  this should give you a file in:
 
-     app/assets/javascripts/users.js.coffee
+    app/assets/javascripts/users.js.coffee
 
 ## Usage
 
 Open your model file and add the cropper:
 
-     class User < ActiveRecord::Base
-       mount_uploader :avatar, AvatarUploader
-       crop_uploaded :avatar  ## Add this
-     end
+    class User < ActiveRecord::Base
+      mount_uploader :avatar, AvatarUploader
+      crop_uploaded :avatar  ## Add this
+    end
 
 Render a view after creating/updating a user, add a `crop` action in your `controller.` For example:
 
-      def create
-        @user = User.new(user_params)
-        respond_to do |format|
-          if @user.save
-            format.html {
-              if params[:user][:avatar].present?
-                render :crop  ## Render the view for cropping
-              else
-                redirect_to @user, notice: 'User was successfully created.'
-              end
-            }
-            format.json { render action: 'show', status: :created, location: @user }
-          else
-            format.html { render action: 'new' }
-            format.json { render json: @user.errors, status: :unprocessable_entity }
-          end

+      @user = User.new(user_params)
+      respond_to do |format|
+        if @user.save
+          format.html {
+            if params[:user][:avatar].present?
+              render :crop  ## Render the view for cropping
+            else
+              redirect_to @user, notice: 'User was successfully created.'
+            end

 3. Supports cropping of ONE attachment per model. Can be directly applied on original attachment if no versions exists.
 
-         process crop: :avatar
+        process crop: :avatar
 
 4. Supports cropping of MULTIPLE versions of one attachment per model.
 5. In form helpers, by default *original image* is rendered. To render a specific version for cropping pass `version` option. For example:
 
-         <%= f.cropbox :avatar , version: :medium %>
-         <%= f.previewbox :avatar , version: :medium %>  ## Pass the same version as specified in cropbox
+        <%= f.cropbox :avatar , version: :medium %>
+        <%= f.previewbox :avatar , version: :medium %>  ## Pass the same version as specified in cropbox
 
 6. By default `previewbox` has `100x100` dimensions and `cropbox` defaults to the target geometry for the version.
    `width` and `height` can be specified for these form helpers. BUT If you override ONE of width/height you MUST override both, otherwise passed option would be ignored.
 
-         <%= f.cropbox :avatar, width: 550, height: 600 %>
-         <%= f.previewbox :avatar, width: 200, height: 200 %>
+        <%= f.cropbox :avatar, width: 550, height: 600 %>
+        <%= f.previewbox :avatar, width: 200, height: 200 %>
 
 7. By default, `process crop: :avatar` will create the cropped version based on original image.
    To resize the image to a particular dimension before cropping, pass two more arguments `width` and `height`.
 
-         ## If ONLY "thumb" version is to be cropped
-         version :jumbo do
-           resize_to_limit(600,600)
-         end
-
-         version :thumb do
-           ## To crop this version based on `jumbo` version, pass width = 600 and height = 600
-           ## Specify both width and height values otherwise they would be ignored
-           process crop: [:avatar, 600, 600]
-           resize_to_limit(100,100)
-         end
+        ## If ONLY "thumb" version is to be cropped
+        version :jumbo do
+          resize_to_limit(600,600)
