+## Components

+- __Client__
+  - a static web application to access IPFS Boards
+- __Cache Server__
+  - can cache boards, helping to serve them via IPFS and via an HTTP gateway to the static web application and the boards' data
+
+__Note:__ until the __IPFS Javascript Implementation__ is done:
+
+- the client (a static web application) requires a full IPFS node because it needs to be able to discover content via the IPFS API.
+- the cache server (written in node) requires a full IPFS node.
+
+__Note:__ if you want to write data, your __IPNS__ needs to be taken over by the application. This problem will be addressed in the future
