-## `ipfs.dag.tree(cid, [options])`
-
-> Enumerate all the entries in a graph
-
-### Parameters
-
-| Name | Type | Description |
-| ---- | ---- | ----------- |
-| cid | [CID][] | A DAG node that follows one of the supported IPLD formats |
-
-### Options
-
-An optional object which may have the following keys:
-
-| Name | Type | Default | Description |
-| ---- | ---- | ------- | ----------- |
-| path | `String` | An optional path within the DAG to resolve |
-| recursive | `boolean` | `false` | If set to true, it will follow the links and continuously run tree on them, returning all the paths in the graph |
-| timeout | `Number` | `undefined` | A timeout in ms |
-| signal | [AbortSignal][] | `undefined` |  Can be used to cancel any long running requests started as a result of this call |
-
-### Returns
-
-| Type | Description |
-| -------- | -------- |
-| `Promise<Array>` | An array with the paths passed |
-
-### Example
-
-```JavaScript
-// example obj
-const obj = {
-  a: 1,
-  b: [1, 2, 3],
-  c: {
-    ca: [5, 6, 7],
-    cb: 'foo'
-  }
-}
-
-const cid = await ipfs.dag.put(obj, { format: 'dag-cbor', hashAlg: 'sha2-256' })
-console.log(cid.toString())

-
-const result = await ipfs.dag.tree('zdpuAmtur968yprkhG9N5Zxn6MFVoqAWBbhUAkNLJs2UtkTq5')
-console.log(result)
-// Logs:
-// a

-// b/0
-// b/1
-// b/2
-// c
-// c/ca
-// c/ca/0
