Under Admin->Layout there is an option for Custom content in home page instead of Q&A.
If you activate this, you can put whatever html you want as your home page.
Welcome to the Q&A site for Question2Answer.
If you have a question about Q2A, please ask here, in English.
To report a bug, please create a new issue on Github or ask a question here with the bug tag.
If you just want to try Q2A, please use the demo site.
