+# Public Site Plan
+
+## Goal
+
+Stand up a small public site on `openjibo.com` that makes the project understandable in a few minutes.
+
+## First Version Content
+
+- project overview
+- current status
+- links to source repositories
+- links to device bootstrap docs
+- explanation of the hosted-cloud direction
+- contribution/contact or waitlist path
+
+## What The Site Should Not Pretend Yet
+
+- zero-touch recovery
+- complete parity with the original cloud
+- public production readiness before device validation is repeatable
+
+## Initial Repo Asset
+
+A simple static site scaffold lives in [src/OpenJibo.Site](C:/Projects/JiboExperiments/OpenJibo/src/OpenJibo.Site).
