 ## Architecture
 
-This conversation type assumes there is some service or application which wishes to generate and receive encrypted content. 
-It also assumes that some other component will be responsible for delivering the generated payloads. 
+This conversation type assumes there is some service or application which wishes to generate and receive end-to-end encrypted content. 
+It also assumes that some other component will be responsible for delivering the generated payloads. At its core this protocol takes the content provided and creates a series of payloads to be sent to the recipient.

+### Content 
+
+Content is provided to the protocol as encoded bytes. 
+Due to segmentation limitations there is a restriction on the maximum size of content. 
+This value is variable and is dependent upon which delivery service is used. 
+In practice content size MUST be less that `255` * `max_seg_size` see: [initialization](#initialization)
+
+Other than its size, the protocol is agnostic of content. 
+
+
 ### Payload Delivery
+
 How payloads are sent and received by clients is not described in this protocol. 
 The choice of delivery method has no impact on the security of this conversation type, though the choice may affect sender privacy and censorship resistance. 
 In practice, any best-effort method of transmitting payloads will suffice, as no assumptions are made.
 
-### Content 
-This protocol expects that all content be wrapped in a ContentFrame as per [CONTENTFRAME](https://github.com/waku-org/specs/blob/jazzz/content_frame/standards/application/contentframe.md) specification. 
-
-This increases observability when issues arise due to client versions mismatches. 
-By enforcing that only ContentFrames will be passed to applications, this creates a clear boundary between Content and protocol owned meta messages.

 ## Implementation Suggestions
 
+### Content Types
+
+Implementors need to be mindful of maintaining interoperability between clients, when deciding how content is encoded prior to transmission.
+In a decentralized context, clients cannot be assumed to be using the same version let alone application. It is recommended that implementors use a self-describing content payload such as [CONTENTFRAME](https://github.com/waku-org/specs/blob/jazzz/content_frame/standards/application/contentframe.md) specification. This provides the ability for clients to determine support for incoming frames, regardless of the software used to receive them.
