 1. Download the cmake-3.20 install script from ([source](https://github.com/Kitware/CMake/releases/download/v3.20.0/cmake-3.20.0-linux-x86_64.sh)).
 
-2. Build diskquota in the Docker container.
-Change <PATH_TO_DISKQUOTA_SRC> and <PATH_TO_CMAKE_INSTALL_SCRIPT> to the appropriate paths on your local machine.
+2. Prepare diskquota-<LAST_DISKQUOTA_TAG>.tar.gz which must contains all <MAJOR>.<MINOR> versions of diskquota. For each versions you need to use last tag (see `git tag`). Name of this archive must be `diskquota-<LAST_DISKQUOTA_TAG>.tar.gz`, where <LAST_DISKQUOTA_TAG> is tag for the latest version of diskquota in this archive. All `*.so` files must be at `lib/postgresql` path:
