+## FAQ: why zmq? dont you know about mqtt?
+
+because i wanted a project to learn zeromq. i am aware of mqtt and
+that it is designed for things like this.
+
+## what is running where?
+
+as this project hasnt been actively worked on for a while, things have
+drifted a little bit. here are some notes for myself.
+
+ * the sensors are _most likely_ running on commit
+   52462cb3d9cee0fc68b7cc908ffe86e95d746bc5 (tagged as
+   `prod-sensors`).
+
+ * the `sink` component **was** running on commit
+   c5e9d2b4124edb97bbade79a70dfada9080511d5 (also tagged as
+   `prod-sink` and branched as `prod-sink` as well).
+
+    **this is no longer true**, sink is running off the `main` branch as of commit 0287dc196914efba4407908e020c146b1733e7ac
