+# Branches
+
+The website is deployed to two separate environments: `dev` and `prod`. The
+code for those environments is kept in the
+[`dev`](https://github.com/cmu-delphi/www-epicast/tree/dev) and
+[`prod`](https://github.com/cmu-delphi/www-epicast/tree/prod) branches,
+respectively.
+
+## `dev` branch
+
+The `dev` branch is deployed to a Delphi-internal development environment where
+we can iterate quickly without worry of breaking the production site.
+
+## `prod` branch
+
+The `prod` branch is deployed to a public-facing production environment. It
+should contain only tested and reliable code.
+
+## process
+
+Changes are selectively merged into `prod` from `dev` after testing. However,
+**`prod` should not be updated while a forecasting round is active** (i.e.
+Friday through Monday), except in case of a critical bugfix.
+
+In any case, all code commits to `prod` should only consist of merges from
+`dev`, rather than direct commits. (An exception to this is configuration,
+which differs between environments.)
