-## Prerequisites
-
-For now, we're assuming building for Debian 11 (stable) x86_64.
-
-Go version 18.4 or later should already be installed, i.e. this runs
-successfully:
-
-* `make all`
-
-## Installing packaging dependencies
-
-```shell
-$ sudo apt install debhelper-compat dh-sequence-bash-completion devscripts
-```
-
-Warining: number of package installed is pretty large considering dependecies.
-
-## Package building
-
-```shell
-$ make debpackage
-```
-
-## Leftovers cleaning
-
-```shell
-$ make debclean
-```
-or
-```shell
-$ dh clean
-```
-
-# Package versioning
-
-By default, package version is based on product version and may also contain git
-tags and hashes.
-
-Package version could be overwritten by setting `PKG_VERSION` variable before
-build, Debian package versioning rules should be respected.
-
-```shell
-$ PKG_VERSION=0.32.0 make debpackge
