+# architecture
+
+This document describes the architecture of the Open-Source Recommender project, highlighting the separation of client and server codebases deployed through AWS using separate branches.
+
+## Branches
+
+The project leverages separate branches for managing and deploying the client and server code:
+
+*client:* This branch houses the code for the user interface and application logic that runs in the web browser (likely using React).
+
+*server:* This branch contains the backend code responsible for handling API requests, data processing, and business logic (built with a framework like FastAPI).
