+# Meld hosting infrastructure
+
+
+## Hosting
+
+* DNS is hosted by Cloudflare
+* SSL/TLS is handled by Cloudflare
+* Website is served by Cloudflare Workers
+* Windows binaries are hosted on the GNOME FTP server mirrors
+* Other package options, including Flatpak releases, are built ond hosted by
+  external providers
+
+Note that the Cloudflare site runs on a private account.
+
+
+## Build
+
+Site build runs on GNOME Gitlab CI, first building the site and publishing to
+Gitlab pages, and then deploying the built static site to Cloudflare. See
+`.gitlab-ci.yml` in the `pages` Git branch for details.
+
+
+## DNS
+
+* meldmerge.org - the main Meld website domain since 2011
+* meld.app - new/secondary website domain, first actually used in 2021
+
+Both domains are privately registered.
+
+
+## Infrastructure TODO list (May 2021)
+
+* Move meldmerge.org hosting from GitHub pages to Cloudflare, or have the
+  GitHub pages site redirect
+* Automate CI release tarball uploads
+* Automate CI release MSI uploads
+* Set release branches to protected if possible; this might not be possible if
+  it will interfere with the GNOME translation team's workflow
