+How to create Ubuntu (or Debian) packages, to be buildable locally or
+in a Ubuntu Launchpad PPA:
+
+1. Check packaging.conf, set maintainer and GnuPG key ID.
+To turn off signatures for local pbuilder build: SKIP_PACKAGE_SIGNING=1
+Note: Launchpad PPA uploads only works with signed packages!
+
+2. Call ./renew-debian-changelog to automatically update the package
+version, according to Git commit and current date. This will update
+debian/changelog and configure.ac.
+
+3. Build Ubuntu/Debian packages:
+- Create package: ./build-deb <distribution>
+distribution: focal, groovy, hirsute, unstable, etc.
+- Create source package and build using pbuilder:
+./build-deb <distribution>
+The result will be in /var/cache/pbuilder/result
+- Create packages for focal, groovy and hirsute + upload to PPA:
+./make-ppa
+Note: dput has to be configured properly (in ~/.dput.cf)!
