## Self-Hosted OpenPhoto FAQ
### How can I install OpenPhoto?
We have lots of guides to help you through the installation process. Check them out here. We welcome contributions on Github if you see one that's incomplete.
### Can I install OpenPhoto to a subdirectory of my site?
Not yet, but it's on our wishlist.
### How does support for multiple users work?
We support multiple users through separate domains. See this issue on why it works that way.
### Is your mobile app available for self-hosted users?
Yes! Download the app for iOS or Android.
### I just changed my domain name. Why am I getting prompted for new settings?
This is normal. OpenPhoto configs are bound to a site, not a server. Since a site is defined by its hostname, you can have multiple sites on one host provided that they have different hostnames. So go ahead and change your settings.
### I encountered a security issue in OpenPhoto. What's the best way to let you know?
Report it as an issue at Github. If you don't feel comfortable exposing a security issue, reach out to someone on the core team and email us individually.
### Something broke. How do I let you know?
Check our issue tracker at Github first; if the issue you're encountering isn't already there, then start a new issue and describe what you ran across.
