## Install

```
npm install @alanshaw/pail
```

## Usage

```js
import { ShardBlock, put, get, del } from '@alanshaw/pail'
import { MemoryBlockstore } from '@alanshaw/pail/block'

// Initialize a new bucket
const blocks = new MemoryBlockstore()
const init = await ShardBlock.create() // empty root shard
await blocks.put(init.cid, init.bytes)

// Add a key and value to the bucket
const { root, additions, removals } = await put(blocks, init.cid, 'path/to/data0', dataCID0)

console.log(`new root: ${root}`)

// Process the diff
for (const block of additions) {
  await blocks.put(block.cid, block.bytes)
}
for (const block of removals) {
