-## matrix_from_metadata_v2
+## matrix_from_metadata_v3
 
-matrix_from_metadata_v2 tool generates a github action matrix from the supported operating systems listed in the module's metadata.json.
+matrix_from_metadata_v3 tool generates a github action matrix from the supported operating systems listed in the module's metadata.json.
 
 How to use it:
-in the project module root directory run `bundle exec matrix_from_metadata_v2`
-
-### --exclude-platforms parameter
-
-matrix_from_metadata_v2 accepts the `--exclude-platforms <JSON array>` argument in order to exclude some platforms from the matrix.
-
-For example:
-
-`$: bundle exec matrix_from_metadata_v2 --exclude-platforms '["debian-11","centos-8"]'`
-
-> Note: The option value should be JSON string otherwise it will throw an error.
-> The values provided in the json array are case-insensitive `["debian-11","centos-8"]'` or `["Debian-11","CentOS-8"]'` are treated as being the same.
-
-### --custom-matrix parameter
-
-matrix_from_metadata_v2 accepts the `--custom-matrix /path/to/matrix.json` argument in order to execute your test suite against a custom matrix. This is useful for use cases that do not fit the default matrix generated.
-
-In order to use this new functionality, run:
-
-`$: bundle exec matrix_from_metadata_v2 --custom-matrix matrix.json`
-
-> Note: The file should contain a valid Array of JSON Objects (i.e. see [here](https://github.com/puppetlabs/puppet_litmus/blob/main/docs/custom_matrix.json)), otherwise it will throw an error.
