-## Installation

-From the library package, install:
-###### `npm install @createjs/build`

 ## Usage
 
 Tasks within this package are run via npm scripts in the library packages. Here is a summary of tasks that this package can run:
 
-###### `npm run build -- [--production] [--combined] [--format=global,module,common]`
+###### `npm run build -- [--production] [--combined] [--format=cjs,iife]`
 
 - transpile and bundle ES2015+ source to ES5 via Rollup & Babel
-- `--production` minified builds
+- `--production` iife build is minified
 - `--combined` from CreateJS package for combined builds
-- `--format` specify which bundle formats to export, defaults to all
+- `--format` specify which Rollup bundle formats to export, defaults to all
 
-###### `npm run plugins -- [--production] [--format=global,common] [--files=FileName]`
+###### `npm run plugins -- [--production] [--format=cjs,iife] [--files=FileName]`
 
 - transpile ES2015+ plugin source to ES5 via Rollup & Babel
-- `--production` minified output
+- `--production` iife build is minified
 - `--format` specify which bundle formats to export, 'module' is disabled
-- `--files` only transpile specific files (sans file extension)
+- `--files` only transpile specific files (no file extension)
 
 ###### `npm run dev`
 
 - transpile and bundle ES2015+ source to ES5 via Rollup & Babel
 - non-minified, includes sourcemaps
-- only bundles 'global' module as that is what is imported by examples
+- only bundles iife module as that is what is imported by examples
 - starts a browser-sync instance for testing examples and tutorials
 - watches source files for changes, re-compiling and reloading browser
