+
+> Analyze file sizes of rollup bundled imports
+
+## install
+
+```sh
+$ npm install --save-dev rollup-analyzer
+```
+
+## api
+
+### init(options)
+set options to use in analysis (this step is optional)
+- **options** *(Object)*
+  - **limit** - *optional*
+    - type: Number
+    - default: `null`
+    - description: Limit number of files to output analysis of, sorted by DESC size
+
+### formatted(bundle)
+returns Promise which resolves with well formatted analysis string (for CLI printing)
+- **bundle** *(Rollup Bundle)* - *required*
+
+### analyze(bundle)
+returns Promise which resolves with array of objects describing each imported file
+- **bundle** *(Rollup Bundle)* - *required*
+
+## usage
+
+```js
+const rollupAnalyzer = require('rollup-analyzer')
+rollup.rollup({/*...*/}).then((bundle) => {
+  // init is an optional step that can be used to set options
+  rollupAnalyzer.init({limit: 5})
+  // print console optimized analysis string
+  rollupAnalyzer.formatted(bundle).then(console.log).catch(console.error)
+})
+
+// Results in ...
