-## Build
-
-With the [Crafter Build](https://forgejo.catcrafts.net/Catcrafts/Crafter.Build)
-Flatpak, which carries the compiler:
-
-```sh
-flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
-flatpak remote-add --if-not-exists catcrafts https://flatpak.catcrafts.net/catcrafts.flatpakrepo
-flatpak install catcrafts net.catcrafts.CrafterBuild//stable
-alias crafter-build='flatpak run net.catcrafts.CrafterBuild//stable'
-crafter-build              # bin/fingerprintd-<target>-<march>/fingerprintd
-crafter-build test         # the unit suites
-```

-Cross-compiling for the phone:

-crafter-build -- --target=aarch64-alpine-linux-musl --sysroot=~/.cache/fingerprintd/sysroot-aarch64-alpine --march=armv8.6-a+fp16fml+aes+sha3+sm4 --mtune=cortex-a720

-## Releases
-
-Every push to `main` is built and tested by CI, which then publishes the
-apks to the Forgejo Alpine registry that installed phones already point at.
-CI treats the registry's "already published" answer as nothing to do, so a
-push publishes only a package version new to the registry. The package
-version is `pkgver-rpkgrel`: `pkgver` is the `Version` constant in
-`interfaces/Fingerprintd.cppm`, `pkgrel` is the APKBUILD's and stays at 0.
-An installed phone picks a published version up with plain `apk upgrade`.
-
-From 0.2.6 on, a release is a range of commits ending in a bump commit
-titled `fingerprintd X.Y.Z` that changes only the version: the constant and
-the APKBUILD's `pkgver`. Each release is tagged `vX.Y.Z` on its bump commit
-(signed, annotated) with the release notes as the tag message, and
-published as a Forgejo release of the same name and text. No version
-before 0.2.6 has a tag or release notes. The notes are written for the
-people whose phones will upgrade:
-
-```
-fingerprintd X.Y.Z

-## New
-
-- **What a user can now do.** One bullet per change, the most important
-  first, with anything the user has to do inside the bullet.
-
-## Fixes
-
-- **What went wrong, in the user's terms.** What they saw, what changes,
-  what to do.
-```
-
-A section with nothing in it is left out, and so is behaviour the release
-does not change. Versioning, from 0.2.6 on, is `MAJOR.MINOR.PATCH`: the
-patch number counts releases, fixes and features alike; the minor number
-moves when a release changes what a user can rely on the daemon for; the
-major number moves when a release changes what an installed phone does
-without being asked.
