 	[--domain=<domain>]
 		Text domain to look for in the source code, unless the `--ignore-domain` option is used.
 		By default, the "Text Domain" header of the plugin or theme is used.
-		If none is provided, it falls back to the plugin/theme slug.
+		If none is provided, it falls back to the project slug.
 
 	[--ignore-domain]
 		Ignore the text domain completely and extract strings with any text domain.
 
-	[--merge[=<file>]]
-		Existing POT file file whose content should be merged with the extracted strings.
-		If left empty, defaults to the destination POT file.
+	[--merge[=<paths>]]
+		Comma-separated list of POT files whose contents should be merged with the extracted strings.
+		If left empty, defaults to the destination POT file. POT file headers will be ignored.
+
+	[--subtract=<paths>]
+		Comma-separated list of POT files whose contents should act as some sort of blacklist for string extraction.
+		Any string which is found on that blacklist will not be extracted.
+		This can be useful when you want to create multiple POT files from the same source directory with slightly
+		different content and no duplicate strings between them.
+
+	[--include=<paths>]
+		Comma-separated list of files and paths that should be used for string extraction.
+		If provided, only these files and folders will be taken into account for string extraction.
+		For example, `--include="src,my-file.php` will ignore anything besides `my-file.php` and files in the `src` directory.
+		Simple glob patterns can be used, i.e. `--include=foo-*.php` includes any PHP file with the `foo-` prefix.
+		Leading and trailing slashes are ignored, i.e. `/my/directory/` is the same as `my/directory`.
 
 	[--exclude=<paths>]
-		Include additional ignored paths as CSV (e.g. 'tests,bin,.github').
-		By default, the following files and folders are ignored: node_modules, .git, .svn, .CVS, .hg, vendor.
+		Comma-separated list of files and paths that should be skipped for string extraction.
+		For example, `--exclude=".github,myfile.php` would ignore any strings found within `myfile.php` or the `.github` folder.
+		Simple glob patterns can be used, i.e. `--exclude=foo-*.php` excludes any PHP file with the `foo-` prefix.
 		Leading and trailing slashes are ignored, i.e. `/my/directory/` is the same as `my/directory`.
+		The following files and folders are always excluded: node_modules, .git, .svn, .CVS, .hg, vendor, *.min.js.
 
 	[--headers=<headers>]
 		Array in JSON format of custom headers which will be added to the POT file. Defaults to empty array.
 
 	[--skip-js]
 		Skips JavaScript string extraction. Useful when this is done in another build step, e.g. through Babel.
 
+	[--file-comment]
+		String that should be added as a comment to the top of the resulting POT file.
+		By default, a copyright comment is added for WordPress plugins and themes in the following manner:
+
+		```
+		Copyright (C) 2018 Example Plugin Author
+		This file is distributed under the same license as the Example Plugin package.
+		```
+
+		If a plugin or theme specifies a license in their main plugin file or stylesheet, the comment looks like this:
+
+		```
+		Copyright (C) 2018 Example Plugin Author
+		This file is distributed under the GPLv2.
+		```
+
+	[--package-name=<name>]
+		Name to use for package name in the resulting POT file's `Project-Id-Version` header.
+		Overrides plugin or theme name, if applicable.
+

+    $ wp i18n make-pot . continents-and-cities.pot --include="wp-admin/includes/continents-cities.php" --ignore-domain
