+====================
+DNF modulesync Plugin
+====================
+
+Download packages from modules and/or create a repository with modular data.
+
+--------
+Synopsis
+--------
+
+``dnf modulesync [options] [<module-spec>...]``
+
+-----------
+Description
+-----------
+
+`modulesync` downloads packages from modules according to provided arguments and creates a repository with modular data
+in working directory. In environment with modules it is recommend to use the command for redistribution of packages,
+because DNF does not allow installation of modular packages without modular metadata on the system (Fail-safe
+mechanism). The command without an argument creates a repository like `createrepo_c` but with modular metadata collected
+from all available repositories.
+
+See examples.
+
+---------
+Arguments
+---------
+
+``<module-spec>``
+ Module specification for the package to download. The argument is an optional.
+
+-------
+Options
+-------
+
+All general DNF options are accepted. Namely, the ``--destdir`` option can be used to specify directory where packages
+will be downloaded and the new repository created. See `Options` in :manpage:`dnf(8)` for details.
+
+
+``-n, --newest-only``
+ Download only packages from the newest modules.
+
+``--enable_source_repos``
+ Enable repositories with source packages
+
+``--enable_debug_repos``
+ Enable repositories with debug-info and debug-source packages
+
+``--resolve``
+ Resolve and download needed dependencies
+
+--------
+Examples
+--------
+
+``dnf modulesync nodejs``
+ Download packages from `nodejs` module and crete a repository with modular metadata in working directory
+
+``dnf download nodejs``
+
+``dnf modulesync``
+ The first `download` command downloads nodejs package into working directory. In environment with modules `nodejs`
+ package can be a modular package therefore when I create a repository I have to insert also modular metadata
+ from available repositories to ensure 100% functionality. Instead of `createrepo_c` use `dnf modulesync`
+ to create a repository in working directory with nodejs package and modular metadata.
+
+``dnf --destdir=/tmp/my-temp modulesync nodejs:14/minimal --resolve``
+ Download package required for installation of `minimal` profile from module `nodejs` and stream `14` into directory
+ `/tmp/my-temp` and all required dependencies. Then it will create a repository in `/tmp/my-temp` directory with
+ previously downloaded packages and modular metadata from all available repositories.
+
+``dnf module install nodejs:14/minimal --downloadonly --destdir=/tmp/my-temp``
+
+``dnf modulesync --destdir=/tmp/my-temp``
+ The first `dnf module install` command downloads package from required for installation of `minimal` profile from module
+ `nodejs` and stream `14` into directory `/tmp/my-temp`. The second command `dnf modulesync` will create
+ a repository in `/tmp/my-temp` directory with previously downloaded packages and modular metadata from all
+ available repositories. In comparison to `dnf --destdir=/tmp/my-temp modulesync nodejs:14/minimal --resolve` it will
+ only download packages required for installation on current system.
