+Welcome to your new Dhall package-set!
+
+Below are instructions for how to edit this file for most use
+cases, so that you don't need to know Dhall to use it.
+
+## Warning: Don't Move This Top-Level Comment!
+
+Due to how `dhall format` currently works, this comment's
+instructions cannot appear near corresponding sections below
+because `dhall format` will delete the comment. However,
+it will not delete a top-level comment like this one.
+
+## Use Cases
+
+Most will want to do one or both of these options:
+1. Override/Patch a package's dependency
+2. Add a package not already in the default package set
+
+This file will continue to work whether you use one or both options.
+Instructions for each option are explained below.
+
+### Overriding/Patching a package
+
+Purpose:
+- Change a package's dependency to a newer/older release than the
+    default package set's release
+- Use your own modified version of some dependency that may
+    include new API, changed API, removed API by
+    using your custom git repo of the library rather than
+    the package set's repo
+
+Syntax:
+Replace the overrides' "{=}" (an empty record) with the following idea
+The "//" or "⫽" means "merge these two records and
+  when they have the same value, use the one on the right:"
+-------------------------------
+let overrides =
+  { packageName =
+      upstream.packageName // { updateEntity1 = "new value", updateEntity2 = "new value" }
+  , packageName =
+      upstream.packageName // { version = "v4.0.0" }
+  , packageName =
+      upstream.packageName // { repo = "https://www.example.com/path/to/new/repo.git" }
+  }
+-------------------------------
+
+Example:
+-------------------------------
+let overrides =
+  { halogen =
+      upstream.halogen // { version = "master" }
+  , halogen-vdom =
+      upstream.halogen-vdom // { version = "v4.0.0" }
+  }
+-------------------------------
+
+### Additions
+
+Purpose:
+- Add packages that aren't already included in the default package set
+
+Syntax:
+Replace the additions' "{=}" (an empty record) with the following idea:
+-------------------------------
+let additions =
+  { package-name =
+       { dependencies =
+           [ "dependency1"
+           , "dependency2"
+           ]
+       , repo =
+           "https://example.com/path/to/git/repo.git"
+       , version =
+           "tag ('v4.0.0') or branch ('master')"
+       }
+  , package-name =
+       { dependencies =
+           [ "dependency1"
