 ## Usage
 
 ### Provide Internet to an interface
 
-```bash
-sudo lnxrouter -i eth1
 ```
-
-no matter which interface (other than `eth1`) you're getting Internet from.
-
-### Create WiFi hotspot
-
-```bash
-sudo lnxrouter --ap wlan0 MyAccessPoint -p MyPassPhrase
+# lnxrouter -i eth1
 ```
 
-no matter which interface you're getting Internet from (even from `wlan0`). Will create virtual Interface `x0wlan0` for hotspot.
-
 ### Provide an interface's Internet to another interface
 
-Clients access Internet through only `isp5`

+```
+# lnxrouter -i eth1 -o vpn0 --dhcp-dns 1.1.1.1
 ```
 
-> In this case of usage, it's recommended to:
-> 
-> 1. Stop serving local DNS
-> 2. Tell clients which DNS to use (ISP5's DNS. Or, a safe public DNS, like above example)

-## What changes are done to Linux system
+## Dependencies
 
-On exit of a linux-router instance, script **will do cleanup**, i.e. undo most changes to system. Though, **some** changes (if needed) will **not** be undone, which are:
+- bash
+- procps or procps-ng
+- iproute2
+- dnsmasq
+- iptables
 
-1. `/proc/sys/net/ipv4/ip_forward = 1` and `/proc/sys/net/ipv6/conf/all/forwarding = 1`
-2. dnsmasq in Apparmor complain mode
-3. hostapd in Apparmor complain mode
-4. Kernel module `nf_nat_pptp` loaded
-5. The wifi device which is used to create hotspot is `rfkill unblock`ed
-6. WiFi country code, if user assigns
