 ## Dependencies
 i3-gaps has some packages that are required for it to work so install these things:
 ```
-sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool 
-```
-You also need to install `libxcb-xrm-dev`, but I got `Unable to locate package libxcb-xrm-dev` when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:
-```
-mkdir tmp
-cd /tmp
-git clone https://github.com/Airblader/xcb-util-xrm
-cd xcb-util-xrm
-git submodule update --init
-./autogen.sh --prefix=/usr
-make
-sudo make install
+sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool libxcb-shape0-dev 
 ```
