 This repo contains Flatpak manifests to distribute Sketchy Maze to Linux users.
 
-It's a work in progress and currently tries to bundle the binary distribution
-from tarball; but the binary uses glibc-2.32 which is not yet available in
-the freedesktop runtime.
+It's a work in progress. It builds the game in the Flatpak SDK but doesn't yet
+handle copying the runtime environment (SFX) and things in.
+
+## Setup
+
+The Doodle source directory should be at a folder named "source" relative
+to this flatpak repo. A symlink can work. For best results, the Doodle source
+folder should be "fully initialized" and ready to simply `go build` the app
+and be done; this means `make doodads` has already been run, and `make bindata`
+to embed them in the Go sources. Generally, if you had run a `make dist` in
+Doodle recently you're good to go.
+
+The `source/go.mod` file should have "replace" directives pointing to the
+appropriate path as seen in the Flatpak build environment, like:
+
+```
+replace git.kirsle.net/go/render => /run/build/doodle/deps/render
+replace git.kirsle.net/go/ui => /run/build/doodle/deps/ui
+replace git.kirsle.net/go/audio => /run/build/doodle/deps/audio
+```
+
+It may be possible to skip the `replace` directives entirely and have `go get`
+download the dependencies the usual way, but the `proxy.golang.org` server
+sometimes caches stale versions of these if they were just recently changed and,
+in case they had bugs, will prevent the app from building.
