+### Using spectrum repository
 We have APT repositories for Debian and Ubuntu that make it very easy to install Spectrum 2.

+### Building packages for different distributions/architectures
+At now we do not have resources to support all different debian-based distributions and/or architectures, but you always can create packages for desired distribution yourself.
+All required files for building Spectrum debian packages are present in the `packaging/debian` directory of spectrum Git repository. Most of required dependencies should be in the main Debian/Ubuntu repositories, except:
+
+1. Swiften - the old Swiften library used by Spectrum is present in stable [Debian](https://packages.debian.org/jessie/libswiften-dev) and [Ubuntu LTS](http://packages.ubuntu.com/trusty/libswiften-dev) but may be missing in unstable/rolling Debian/Ubuntu trees. However, you can use their own [Debian/Ubuntu repository](https://github.com/hanzz/spectrum2/blob/master/.travis.yml#L10) or create packages yourself using the same method described here for Spectrum :)
+2. Communi - this library is unavailable in Debian/Ubuntu, but we provide a special [repository](https://github.com/vitalyster/libcommuni-gbp) from which you can build libcommuni

+#### Packaging for your current distribution

+#### Creating package for different debian-based distro
+We will show how to build Spectrum for the popular [Raspberry Pi](https://www.raspberrypi.org/) (or any similar) ARM-based machine with Debian-based distribution installed on it
