+
+![Device Details][screen1]
+
+
+## Main Info
+  - **MAC**: MAC addres of the device. Not editable.
+  - **Name**: Friendly device name
+  - **Owner**: Device owner (The list is self-populated with existing owners)
+  - **Type**: Select a device type from the dropdown list (Smartphone, Table,
+      Laptop, TV, router, ....) or type a new device type
+  - **Vendor**: Automatically updated by Pi.Alert
+  - **Favorite**: Mark the device as favorite and then it will appears at the
+      begining of the device list
+  - **Group**: Select a grouper ('Always on', 'Personal', Friends') or type
+      your own Group name
+  - **Comments**: Type any comments for the device
+
+## Session Info
+  - **Status**: Show device status : On-line / Off-Line
+  - **First Session**: Date and time of the first connection
+  - **Last Session**: Date and time of the last connection
+  - **Last IP**: Last known IP used during the last connection
+  - **Static IP**: Check this box to identify devices that always use the
+      same IP
+
+## Events & Alerts config
+  - **Scan Cycle**: Select the scan cycle: 0, 1', 15'
+    - Some devices do not respond to all ARP packets, for this cases is better
+      to use a 15' cycle.
+    - **For Apple devices I recommend using 15' cycle**
+  - **Alert All Events**: Send a notification in each event (connection,
+      disconnection, IP Changed, ...)
+  - **Alert Down**: Send a notification when the device is down
+    - *(Userful with "always connected" devices: Router, AP, Camera, Alexa,
+      ...)*
+  - **Skip repeated notifications during**: Do not send more than one
+      notification to this device for X hours
+    - *(Useful to avoid notification saturation on devices that frequently
+      connects and disconnects)*
+
+# Privacy & Random MAC's
+<!--- --------------------------------------------------------------------- --->
+
+The latest versions of some operating systems (IOS and Android) incorporate a
+new & interesting functionality to improve privacy: **Random MACs**.
+
+This functionality allows you to **hide the true MAC** of the device and
+**assign a random MAC** when we connect to WIFI networks.
+
+This behavior is especially useful when connecting to WIFI's that we do not
+know, but it **is totally useless when connecting to our own WIFI's** or known
+networks.
+
+**I recommend disabling this operation when connecting our devices to our own
+WIFI's**, in this way, Pi.Alert will be able to identify the device, and it
+will not identify it as a new device every so often (every time IOS or Android
+decides to change the MAC).
