Add \E[1mzmodule\E[0m calls to your \E[1m'${ztarget}$'\E[0m file to define the modules to be initialized.
The initialization will be done in the same order it\'s defined.

  <url>                      Module absolute path or repository URL. The following URL formats
                             are equivalent: \E[1mfoo\E[0m, \E[1mzimfw/foo\E[0m, \E[1mhttps://github.com/zimfw/foo.git\E[0m.
                             If an absolute path is given, the module is considered externally
                             installed and won\'t be installed or updated by zimfw.
  \E[1m-n\E[0m|\E[1m--name\E[0m <module_name>    Set a custom module name. Default: the last component in <url>.
                             Slashes can be used inside the name to organize the module into
                             subdirectories. The module will be installed at
                             \E[1m'${ZIM_HOME}$'/\E[0m<module_name>.
  \E[1m-r\E[0m|\E[1m--root\E[0m <path>           Relative path to the module root.

Per-module options:
  \E[1m-b\E[0m|\E[1m--branch\E[0m <branch_name>  Use specified branch when installing and updating the module.
                             Overrides the tag option. Default: the repository default branch.
  \E[1m-t\E[0m|\E[1m--tag\E[0m <tag_name>        Use specified tag when installing and updating the module. Over-
                             rides the branch option.
  \E[1m-u\E[0m|\E[1m--use\E[0m <tool_name>       Install and update the module using the defined tool. Default is
                             either defined by \E[1mzstyle \':zim:zmodule\' use \'\E[0m<tool_name>\E[1m\'\E[0m, or \E[1mgit\E[0m
                             if none is provided. The tools available are:
                             \E[1mgit\E[0m uses the git command. Local changes are preserved on updates.
                             \E[1mdegit\E[0m uses curl or wget, and currently only works with GitHub
                             URLs. Modules install faster and take less disk space. Local
                             changes are lost on updates. Git submodules are not supported.
                             \E[1mmkdir\E[0m creates an empty directory. The <url> is only used to set
                             the module name. Use the \E[1m-c\E[0m|\E[1m--cmd\E[0m or \E[1m--on-pull\E[0m options to execute
                             the desired command to generate the module files.
  \E[1m--no-submodules\E[0m            Don\'t install or update git submodules.
  \E[1m-z\E[0m|\E[1m--frozen\E[0m                Don\'t install or update the module.

  The per-module options above are carried over multiple zmodule calls for the same module.
  Modules are uniquely identified by their name.

Per-module-root options:
  \E[1m--if\E[0m <test>                Will only initialize module root if specified test returns a zero
                             exit status. The test is evaluated at every new terminal startup.
  \E[1m--if-command\E[0m <cmd_name>    Will only initialize module root if specified external command is
                             available. This is evaluated at every new terminal startup.
                             Equivalent to \E[1m--if \'(( \${+commands[\E[0m<cmd_name>\E[1m]} ))\'\E[0m.
  \E[1m--on-pull\E[0m <command>        Execute command after installing or updating the module. The com-
                             mand is executed in the module root directory.
  \E[1m-d\E[0m|\E[1m--disabled\E[0m              Don\'t initialize the module root or uninstall the module.

  The per-module-root options above are carried over multiple zmodule calls for the same mod-
  ule root.

Per-call initialization options:
  \E[1m-f\E[0m|\E[1m--fpath\E[0m <path>          Will add specified path to fpath. The path is relative to the
                             module root directory. Default: \E[1mfunctions\E[0m, if the subdirectory
                             exists and is non-empty.
  \E[1m-a\E[0m|\E[1m--autoload\E[0m <func_name>  Will autoload specified function. Default: all valid names inside
                             the \E[1mfunctions\E[0m subdirectory, if any.
  \E[1m-s\E[0m|\E[1m--source\E[0m <file_path>    Will source specified file. The path is relative to the module
                             root directory. Default: \E[1minit.zsh\E[0m, if a non-empty \E[1mfunctions\E[0m sub-
                             directory exists, else the largest of the files matching the glob
                             \E[1m(init.zsh|\E[0m<name>\E[1m.(zsh|plugin.zsh|zsh-theme|sh))\E[0m, if any.
                             <name> in the glob is resolved to the last component of the mod-
                             ule name, or the last component of the path to the module root.
  \E[1m-c\E[0m|\E[1m--cmd\E[0m <command>         Will execute specified command. Occurrences of the \E[1m{}\E[0m placeholder
                             in the command are substituted by the module root directory path.
                             I.e., \E[1m-s \'foo.zsh\'\E[0m and \E[1m-c \'source {}/foo.zsh\'\E[0m are equivalent.

  Setting any per-call initialization option above will disable the default values from the
  other per-call initialization options, so only your provided values will be used. I.e. these
  values are either all automatic, or all manual in each zmodule call. To use default values
  and also provided values, use separate zmodule calls.'

Actions:
  \E[1mbuild\E[0m           Build \E[1m'${ZIM_HOME}$'/init.zsh\E[0m and \E[1m'${ZIM_HOME}$'/login_init.zsh\E[0m.
                  Also does \E[1mcompile\E[0m. Use \E[1m-v\E[0m to also see its output.
  \E[1mclean\E[0m           Clean all. Does both \E[1mclean-compiled\E[0m and \E[1mclean-dumpfile\E[0m.
  \E[1mclean-compiled\E[0m  Clean Zsh compiled files.
  \E[1mclean-dumpfile\E[0m  Clean completion dumpfile.
  \E[1mcompile\E[0m         Compile Zsh files.
  \E[1mhelp\E[0m            Print this help.
  \E[1minfo\E[0m            Print zimfw and system info.
  \E[1mlist\E[0m            List all modules currently defined in \E[1m'${ZIM_CONFIG_FILE:-${ZDOTDIR:-${HOME}}/.zimrc}$'\E[0m.
                  Use \E[1m-v\E[0m to also see the modules details.
  \E[1minit\E[0m            Same as \E[1minstall\E[0m, but with output tailored to be used at terminal startup.
  \E[1minstall\E[0m         Install new modules. Also does \E[1mbuild\E[0m, \E[1mcompile\E[0m. Use \E[1m-v\E[0m to also see their
                  output, any on-pull output and skipped modules.
  \E[1muninstall\E[0m       Delete unused modules. Prompts for confirmation. Use \E[1m-q\E[0m for quiet uninstall.
  \E[1mcheck\E[0m           Check if updates for current modules are available. Use \E[1m-v\E[0m to also see
                  skipped and up to date modules.
  \E[1mupdate\E[0m          Update current modules. Also does \E[1mbuild\E[0m, \E[1mcompile\E[0m. Use \E[1m-v\E[0m to also see their
                  output, any on-pull output and skipped modules.
  \E[1mcheck-version\E[0m   Check if a new version of zimfw is available.
  \E[1mupgrade\E[0m         Upgrade zimfw. Also does \E[1mcompile\E[0m. Use \E[1m-v\E[0m to also see its output.
  \E[1mversion\E[0m         Print zimfw version.

Options:
  \E[1m-q\E[0m              Quiet (yes to prompts and only outputs errors)
  \E[1m-v\E[0m              Verbose (outputs more details)'
