* [node-sha3](https://github.com/phusion/node-sha3) -- **MAKE SURE** to use [steakknife's fork](https://github.com/steakknife/node-sha3) if [the FIPS 202 upgrade](https://github.com/phusion/node-sha3/pull/25) hasn't been merged (otherwise, you'll run into all kinds of hashing problems)
## Development
```js
git clone git@github.com:bigchaindb/js-bigchaindb-driver.git
cd js-bigchaindb-driver/
npm i
npm run dev
```
After updating source files in `src/`, make sure to update the API documentation. The following command will scan all source files and create the Markdown output into `./API.md`:
```bash
npm run doc
```
