 # Universal JS Boilerplate
 
+[![CI](https://github.com/jakejarvis/npm-module-template/actions/workflows/ci.yml/badge.svg)](https://github.com/jakejarvis/npm-module-template/actions/workflows/ci.yml)

+
 Just a personal boilerplate to my liking for an Node and/or browser module w/ ESM, CommonJS, and UMD outputs via Babel & Rollup. Ready to publish on NPM and/or GitHub Packages and distibute via unpkg, skypack.dev, etc.
 
 Probably not very useful to anybody else. 😊
 
+## Usage
+
+### something(options?)
+
+#### options
+
+Type: `object`
+
+##### doSomething
+
+Type: `boolean`\
+Default: `false`
+
+Makes it do something.
+
