-On your browser, you should use `localhost` instead of `0.0.0.0`. This is because webrtc generally requires a secure connection (https), but [an exception is made](https://w3c.github.io/webappsec-secure-contexts/#localhost) specifically for localhost and domains that end in `.localhost`.
+## Basic
+
+If you're just working on the interface and don't need to test connections to other computers, you can point your browser to `localhost` instead of `0.0.0.0`. Webrtc generally requires a secure connection (https), but [an exception is made](https://w3c.github.io/webappsec-secure-contexts/#localhost) specifically for localhost and domains that end in `.localhost`.
+
+## Developing / Testing Communications
+
+If you need to test communication, you may get away with opening two browser windows to the same URL on `localhost`. However this may be of limited utility, especially if you're confirming that sound works appropriately. In order to test on two computers, you'll need your dev computer to serve on an IP address accessible from the other computer, at which point you will no longer get away with using `localhost`. You will need SSL certs, though for dev purposes they can be self-signed.
+
+[Generate your certificate](https://serverfault.com/a/224127), which will give you your cert and key files. In `settings.js`, set the full path to them on your file system:
+
+    "ssl" : {
+      "key"  : "/path-to-your/epl-server.key",
+      "cert" : "/path-to-your/epl-server.crt"
+      // "ca" - not needed for dev purposes
+    }
+
+Point your browser to your outward facing IP address, preceeded by `https://`, and accept the security warning (since this is a self-signed cert).
