 ## Features
-* Create an AP (Access Point) at any channel.
-* Choose one of the following encryptions: WPA, WPA2, WPA/WPA2, Open (no encryption).
-* Hide your SSID.
-* Disable communication between clients (client isolation).
-* IEEE 802.11n & 802.11ac support
-* Internet sharing methods: NATed or Bridged or None (no Internet sharing).
-* Choose the AP Gateway IP (only for 'NATed' and 'None' Internet sharing methods).
-* You can create an AP with the same interface you are getting your Internet connection.
-* You can pass your SSID and password through pipe or through arguments (see examples).

 ### General
-* bash (to run this script)
-* util-linux (for getopt)
-* procps or procps-ng
-* hostapd
-* iproute2

 ## Installation
+
 ### Generic
+
     git clone https://github.com/lakinduakash/linux-wifi-hotspot
     cd linux-wifi-hotspot/src/scripts
     make install
 
 ### ArchLinux
+
     pacman -S create_ap
 
 ### Gentoo
+
     emerge layman
     layman -f -a jorgicio
     emerge net-wireless/create_ap
 
 ## Examples
+
 ### No passphrase (open network):
+
     create_ap wlan0 eth0 MyAccessPoint
 
 ### WPA + WPA2 passphrase:
+
     create_ap wlan0 eth0 MyAccessPoint MyPassPhrase
 
 ### AP without Internet sharing:
+
     create_ap -n wlan0 MyAccessPoint MyPassPhrase
 
 ### Bridged Internet sharing:
+
     create_ap -m bridge wlan0 eth0 MyAccessPoint MyPassPhrase
 
 ### Bridged Internet sharing (pre-configured bridge interface):
+
     create_ap -m bridge wlan0 br0 MyAccessPoint MyPassPhrase
 
 ### Internet sharing from the same WiFi interface:
+
     create_ap wlan0 wlan0 MyAccessPoint MyPassPhrase
 
 ### Choose a different WiFi adapter driver
+
     create_ap --driver rtl871xdrv wlan0 eth0 MyAccessPoint MyPassPhrase
 
 ### No passphrase (open network) using pipe:
+
     echo -e "MyAccessPoint" | create_ap wlan0 eth0
 
 ### WPA + WPA2 passphrase using pipe:
+
     echo -e "MyAccessPoint\nMyPassPhrase" | create_ap wlan0 eth0
 
 ### Enable IEEE 802.11n
+
     create_ap --ieee80211n --ht_capab '[HT40+]' wlan0 eth0 MyAccessPoint MyPassPhrase
 
 ### Client Isolation:
+
     create_ap --isolate-clients wlan0 eth0 MyAccessPoint MyPassPhrase
 
+### Assign IP address to a hosts listed in /etc/hosts:
+
+    create_ap --dhcp-hosts "host1 host2" wlan0 eth0 MyAccessPoint MyPassPhrase
+
+### Assign IP address to two hosts not listed in /etc/hosts:
+
+    create_ap --dhcp-hosts "host1,192.168.12.2 host2,192.168.12.3" wlan0 eth0 MyAccessPoint MyPassPhrase
+
+Use a space to separate multiple `dhcp-host` definitions. Reference [dnsmasq.conf.example](https://github.com/imp/dnsmasq/blob/770bce967cfc9967273d0acfb3ea018fb7b17522/dnsmasq.conf.example#L238) for other valid ways to define hosts, such as by MAC address.
+
 ## Systemd service
+
 Using the persistent [systemd](https://wiki.archlinux.org/index.php/systemd#Basic_systemctl_usage) service
+
 ### Start service immediately:
+
     systemctl start create_ap
