```

You can import `blockstack.js` as a script without using a package manager. To securely use the latest distribution of blockstack.js from a CDN, add [the mdincludes/script-dist-file.md](mdincludes/script-dist-file.md) script in your application. 


## About

Blockstack JS is a library for profiles/identity, authentication, and storage.

The authentication portion of this library can be used to:

1.  create an authentication request
2.  create an authentication response

The profiles/identity portion of this library can be used to:

1.  transform a JSON profile into cryptographically-signed tokens
2.  recover a JSON profile from signed tokens
3.  validate signed profile tokens

The storage portion of this library can be used to:

1. store and retrieve your app's data in storage that is controlled by the user

_Note: this document uses ES6 in its examples but it is compiled down to Javascript (ES5) and is perfectly compatible with it. If you're using the latter, just make a few adjustments to the examples below (e.g. use "let" instead of "var")._

## Documentation
