+# FDC3 For The Web 
+
+This is a minimal proof-of-concept for FDC3 For the Web.
+
+## To Run
+
+1.  From the Command Line:
+    ```
+    yarn install
+    yarn vite dev
+    ```
+
+2. Point browser at http://localhost:5000/static/da/
+
+3. This is your dummy desktop agent, which has two apps you can launch:
+
+    - App1 Can Broadcast via FDC3.
+    - App2 Listens.
+
+4. Launch the apps, press the button, watch messages pass between them.
+
+## What This Project Contains
+
+ - In `\lib`:  A minimal implementation called `webc3.ts`.  This relies on the `post-message` strategy for communicating between apps and the desktop agent.  This supports two functions:
+
+   - `supply`:  Called by the desktop agent on startup, allows it to supply FDC3 APIs to apps when they ask for one.
+
+   - `load`: Called (with options) by an FDC3 Aoo to retrieve the API.
+
+ - In `\demo`:  A fixture for demonstrating the above, containing two apps, `app1` and `app2` and a rudimentary `dummy-desktop-agent` all of which use the `webc3.ts` library.
+
+## Notes
+
+- Since this uses Vite, you can modify the code and see it running the browser immediately.
+- This currently only supports FDC3 2.0
