 This specification describes the parameters used in the manifest for a Codex client application.
 
 ## Background
-The manifest is the default configuration for a Codex client. 
-The file contains key-value pairs that are configuirable.
-The structured format used is JSON.
+The manifest is used to encode datasets with the a Codex client. 
+The file contains key-value pairs.
