 1. **Provider (`provider/`)**
     - Implements low-level WASM operations for:
-        - Memory management and allocation
-        - Input/output serialization
-        - Context lifecycle management
-    - Used by the API layer for high-level operations
-    - Integrates with trampoline for WASM module linking
+        - Reading function input
+        - Serializing the function output
 
 2. **Core (`core/`)**
-    - Defines fundamental types and interfaces
-    - Used by both API and provider layers
+    - Defines common types used by the `providers` and `api`
 
 3. **API (`api/`)**
-    - High-level Rust interface for writing Shopify Functions
+    - Provides a high-level interface for interacting with the provider
+    - Abstracts away low-level WASM details
     - Includes examples and documentation
 
 4. **Trampoline (`trampoline/`)**
-    - Bridges communication between WASM modules
+    - CLI tool that augments WASM modules to interface with the provider
+    - Handles memory sharing between guest and provider modules
+    - Creates the necessary WASM imports/exports
