+## Abstract
+
+This specification describes the parameters used in the manifest for a Codex client application.
+
+## Manifest
+The manifest is used to encode datasets with the a Codex client node. 
+The file contains key-value pairs.
+
+### Parameters
+
+```json
+
+"manifest" : {
+	"treeCid" : "string"
+	"datasetSize" : ,
+	"blockSize" : ,
+	"codec" : ,
+	"hcodec" : ,
+	"version" : ,
+	"protected" : "bool",
+	"ecK" : "int",
+	"ecM" : "int",
+	"originalTreeCid" : ,
+	"originalDatasetSize" :
+	"protectedStrategy" :
+	"verifiable" : "bool" ,
+	"verifyRoot" : ,
+	"slotRoots" : ,
+	"cellSize" : ,
+	"verifiableStrategy" : ,
+	
+}
+
+```
+
+The structured format used is JSON.
+
+| attribute | type | description |
+|-----------|------|-------------|
+| `treeCid` | string | A hash based on [CIDv1](https://github.com/multiformats/cid#cidv1). The root of the merkle tree |
+| `datasetSize` | bytes | Total size of all blocks, after data is chunked. |
+| `blockSize` | bytes | Size of each contained block. |
+| `codec` | [MultiCodec](https://github.com/multiformats/multicodec) |  A dataset codec. |
+| `hcodec` | [MultiCodec](https://github.com/multiformats/multicodec) | A multihash codec. |
+| `version` | string | The CID version |
+| `protected` | bool | The protected datasets have erasure coded info, If true, `ecK`, `ecM`, `originalTreeCid`, `originalDatasetSize`, and `protectedStrategy` SHOULD be used.|
+| `ecK` | int | The number of blocks to encode. |
+| `ecM` | int | The number of resulting parity blocks. |
+| `originalTreeCid` | string | The original root of the dataset being erasure coded. |
+| `originalDatasetSize` | bytes | The size of the original dataset. |
+| `protectedStrategy` | enum | An indexing strategy used to build the slot roots. |
+| `verifiable` | bool | Verifiable datasets can be used to generate storage proofs. If true, `verifyRoot`, `slotRoots`, `cellSize`, and `verifiableStrategy` SHOULD be used. |
+| `verifyRoot` | string | The root of the top level merkle tree built from slot roots. |
+| `slotRoots` | array[string] | Individual slot root built from the original dataset blocks. |
+| `cellSize` | bytes | The size of each slot cell. |
+| `verifiableStrategy` | enum | Indexing strategy used to build the slot roots. |
