+### Peek
+
+[Peek](https://github.com/phw/peek#debian) is a GIF recorder for Linux.
+
+There are no official Debian packages, yet, but you can easily create your own .deb package for Peek. First, install the build dependencies:
+
+```shell
+sudo apt install cmake valac libgtk-3-dev libkeybinder-3.0-dev libxml2-utils gettext txt2man
+```
+
+Then build Peek and package it:
+
+```shell
+git clone https://github.com/phw/peek.git
+mkdir peek/build
+cd peek/build
+cmake -DCMAKE_INSTALL_PREFIX=/usr -DGSETTINGS_COMPILE=OFF ..
+make package
+```
+
+This will create the package peek-x.y.z-Linux.deb (where x.y.z is the current version). You can install it with dpkg:
+
+```shell
+sudo dpkg -i peek-*-Linux.deb
+```
