 This page visualizes the core workflow interfaces in the TPEN Application. This is a work in progress and will be updated as the workflow evolves.

+
+## TPEN Navigation Map
+
+This section provides a clear visual overview of how the TPEN ecosystem components interlink. The diagrams are organized from high-level system architecture down to specific workflows.
+
+---
+
+### 1. System Overview
+
+High-level view of the major TPEN components and how they connect.
+
+```mermaid

+
+### 2. User Entry & Authentication Flow
+
+How users access TPEN from the documentation site through authentication to the application.
+
+```mermaid
+graph TB

+
+### 3. Application Dashboard & Project Access
+
+Main navigation within the app.t-pen.org dashboard.
+
+```mermaid

+
+### 4. Project Management Workflow
+
+Interfaces for project leaders to configure and manage projects.
