For free products, we only offer Support through Github. To say it bluntly, we can't afford to offer human-based support for our free products. If you have a custom question as a user of our free products, first, you'll need to subscribe to one of our plans.
However, we aim to keep all our users satisfied with the quality of our products, therefore, we have created extensive documentations to guide you through installing and using our products. Please check the product's documentation, and if you still cannot find your answer, leave a comment on the Github product's page.
