# Quad9 Documentation Quad9 Public-Facing Documentation available at [docs.quad9.net](https://docs.quad9.net) using [mkdocs-material](https://github.com/squidfunk/mkdocs-material). # New Article Requests or Corrections Pull requests are allowed for typos and minor corrections only. New articles will likely not be merged, since they will need to be translated. Please open an Issue in GitHub or [open a support ticket](https://quad9.net/support/contact) for requesting net-new articles. # Consumer Routers Due to the sheer amount of consumer-grade router makes, models, and variances in user interfaces between firmware versions, we will typically not add router-specific instructions. Open-source router software (IPFire, OPNsense, pfSense, etc) is supported, since we can test in a lab environment with VMs and do not require physical access to a device.
