Hi, thanks for your contribution.

However, there are no tagged releases for this project. Our guidelines require that Any software project you are adding was first released more than 4 months ago. We encourage you to create a release now and/or a simple changelog that will help users keep track of changes in the software (especially breaking changes or changes requiring configuration tweaks), and will allow administrators to install a known working, unchanging version (as opposed to always installing the latest development version).

Once this is done, the project may be resubmitted to awesome-selfhosted when the first release reaches the age of 4 months.

Thanks for understanding, and good luck with this project.
