-== Security Warning ==
+== Overview ==
-The current version of WiFi debugging is '''not authenticated or encrypted'''.  This means that, if you enable it as described below:
+WiFi debugging allows WebIDE to connect to your Firefox OS device via your local WiFi network instead of a USB cable.
-* Anyone on the same WiFi network can connect to your device with the DevTools
+The connection experience is generally more straightforward (especially after connecting to a device the first time) than with USB and also more convenient to use since you're no longer tied down by a cable.
-* Anyone on the same WiFi network can read your debugging traffic (which can include full requests, responses, etc.)
-Because of this, it would be wise to avoid enabling this feature at this time on a device with data that is sensitive or personal in any way.  These issues will be resolved before this feature is available by default.
+== Security ==
-== Overview ==
+WiFi debugging uses TLS for encryption and authentication over the WiFi network.  Each device creates a self-signed certificate for authentication.  When connecting, a QR code is scanned to verify the certificates were presented by the correct devices.  After the first connection, these certs can be remembered to allow for immediate connection if desired.

+== Enabling ==
-The connection experience is generally more straightforward (especially after connecting to a device the first time) than with USB and also more convenient to use since you're no longer tied down by a cable.
+As of [https://bugzil.la/1027454 bug 1027454], this feature is no longer hidden.  Assuming you have Firefox 39 for desktop and Firefox 3.0 on device, you can enable this feature on the device:
-== Toggle Feature Flags ==
+# Go to Developer Settings on device (Settings -> Developer)
+# Enable DevTools via Wi-Fi
+# Edit the device name if desired
-Since this feature is still under heavy development, there are few things you must do make it available:
+== Connect ==
-* In Firefox Nightly:
+# Open WebIDE in Firefox Nightly (Tools -> Web Developer -> WebIDE)
-** Set the pref <code>devtools.remote.wifi.scan</code> to <code>true</code>
+# Click "Select Runtime" to open the runtimes panel
-* On Firefox OS:
+# Your Firefox OS device should show up in the "WiFi Devices" section
-** Set the pref <code>devtools.remote.wifi.visible</code> to <code>true</code>
+# A connection prompt will appear on device, choose "Scan" or "Scan and Remember"
-*** This exposes a UI option to control WiFi debugging from Settings -> Developer
+# Scan the QR code displayed in WebIDE
