+# Building Debian package on host
+
+## 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
+```
