 ## What This Tool Does
-Signal CGM is a B2B CGM coverage worklist tool for DMEPOS suppliers.
-It ingests shipment data (CSV from Brightree/WellSky), calculates
-coverage expiration per patient using device wear-day rules, and
-produces a prioritized worklist so small DME teams can do proactive
-outreach BEFORE claims deny.
+Signal is a B2B CGM documentation readiness tracker for DMEPOS suppliers.
+It ingests order data from any DME order management CSV export (e.g., Brightree),
+evaluates each patient against documentation requirements (6-month qualifying
+visit, PECOS enrollment, SWO, resupply eligibility), and produces a Signal Report
+so supplier staff can prioritize outreach and capture revenue before it leaks.
+NOTE: Signal identifies gaps. It does not conduct outreach. Never write copy
+implying Signal contacts prescribers or patients directly.
