+##### Path
+
+A function that returns the path to the js-ipfs CLI.
+
+This is analogous to the `.path()` function exported by the [go-ipfs](https://www.npmjs.com/package/go-ipfs) module.
+
+###### `path()`
+
+Returns the path to the js-ipfs CLI
+
+###### Example
+
+```js
+import { path } from 'ipfs'
+
+console.info(path()) // /foo/bar/node_modules/ipfs/src/cli.js
+```
