 # ble
 Bluetooth LE related programs
+
+- bledevice.py : basic class module for BLE devices
+- blecomm.py : test program for communicating with an HM-10 BLE module
+- blebulb.py : control program for Zengge BLE bulb
+- yeelight.py : control program for Yeelight bedside lamp
+- beacon : iBeacon and Google Eddystone related programs
+
+To use these programs, you have to install bluez and python pexpect module.
+
+The [bluez](http://www.elinux.org/RPi_Bluetooth_LE) (Bluetooth stack for linux) package can be installed by executing the following command:
+````
+sudo apt-get install bluetooth blueman bluez python-gobject python-gobject-2
+````
+
+The [pexpect](http://pexpect.readthedocs.org/en/stable/) module can be installed as follows:
+````
+sudo pip install pexpect
+````
