Add %Bzmodule%b calls to your %B${ZDOTDIR:-${HOME}}/.zimrc%b file to define the modules to be initialized.
The modules are initialized in the same order they are defined.

  <url>                      Module absolute path or repository URL. The following URL formats
                             are equivalent: %Bname%b, %Bzimfw/name%b, %Bhttps://github.com/zimfw/name.git%b.
  %B-n%b|%B--name%b <module_name>    Set a custom module name. Default: the last component in the <url>.

Repository options:
  %B-b%b|%B--branch%b <branch_name>  Use specified branch when installing and updating the module.
                             Overrides the tag option. Default: the repository's default branch.
  %B-t%b|%B--tag%b <tag_name>        Use specified tag when installing and updating the module.
                             Overrides the branch option.
  %B-u%b|%B--use%b <%Bgit%b|%Bdegit%b>       Install and update the module using the defined tool. Default: %Bgit%b

Initialization options:
  %B-f%b|%B--fpath%b <path>          Add specified path to fpath. The path is relative to the module
                             root directory. Default: %Bfunctions%b, if the subdirectory exists.
  %B-a%b|%B--autoload%b <func_name>  Autoload specified function. Default: all valid names inside the
                             module's specified fpath paths.
  %B-s%b|%B--source%b <file_path>    Source specified file. The file path is relative to the module root
                             directory. Default: %Binit.zsh%b, if the %Bfunctions%b subdirectory also
                             exists, or the file with largest size matching
                             %B{init.zsh,module_name.{zsh,plugin.zsh,zsh-theme,sh}}%b, if any exist.
  %B-c%b|%B--cmd%b <command>         Execute specified command. Occurrences of the %B{}%b placeholder in the
                             command are substituted by the module root directory path.
                             %B-s 'script.zsh'%b and %B-c 'source {}/script.zsh'%b are equivalent.
  %B-d%b|%B--disabled%b              Don't initialize or uninstall the module.
