 ## Adding your distribution to `wsl --install` for all WSL users
 
-To make your WSL distribution available to all users, open a pull request on the [WSL GitHub repository](https://github.com/microsoft/WSL) that modifies the [DistributionInfo.json](https://github.com/microsoft/WSL/blob/master/distributions/DistributionInfo.json) file to include your distribution information.
+In order for your distribution to be included in the list for the command: `wsl --list --online`, the distribution must meet the [Membership criteria](https://oss-security.openwall.org/wiki/mailing-lists/distros#membership-criteria) outlined in the distribution mailing list. This ensures that all listed distributions adhere to the necessary security standards.
 
-This pull request will be reviewed by the WSL team.
+If your distribution meets the criteria and you would like to add it to the `--install` list, submit a pull request on the WSL GitHub repository (https://github.com/microsoft/WSL) that updates the [DistributionInfo.json file](https://github.com/microsoft/WSL/blob/master/distributions/DistributionInfo.json) with your distribution's details. This pull request will be reviewed by the WSL team.
