+### Added
+- An optional way to support development. Settings → About now has a "Support
+  development" button that opens Ko-fi in your browser. It's a plain donation
+  link with no perks attached, and it needs no new permissions — Calendula still
+  has no internet access of its own and just hands the link to your browser.

-Calendula ships through a self-hosted F-Droid repository; every version tag
-is built, signed, and published there automatically.
+### F-Droid (recommended)
 
-1. Install an F-Droid client ([F-Droid](https://f-droid.org), Droid-ify, Neo

+just search for **Calendula** in any F-Droid client, or

+
+### Self-hosted repo (latest builds)
+
+New versions are built, signed, and published to a self-hosted repository the
+moment each tag lands — usually a few days ahead of the official repo, which
+rebuilds on F-Droid's own schedule. Add it for the freshest builds:
+
+1. In your F-Droid client, open *Settings → Repositories → Add* (or open the

-## 🛠 Building
+## 📚 Documentation
 
-Requires Android SDK 36+ and JDK 17. The Gradle wrapper is checked in:
-
-```bash
-./gradlew assembleDebug   # debug APK
-./gradlew test            # JVM unit tests
-./gradlew lint            # Android lint
-```
-
-If your default JDK is not 17, set `JAVA_HOME` explicitly.
-
-## 🏗 Architecture
-
-Single-activity Compose app, layered `UI → Repository → DataSource →
-CalendarContract`, observer-driven refresh, JVM-first tests. The full tour —
-including the recurring-write and reminder pipelines — lives in
-[docs/ARCHITECTURE.md](docs/ARCHITECTURE.md).
-
-## 🗺 Roadmap
-
-Shipped: read (v1.0), write (v1.1–v2.0), reminder delivery (v1.4).
-Next up: power-user features — widget, search, tablet layouts. The living
-roadmap is in [.planning/ROADMAP.md](.planning/ROADMAP.md), the release
-history in [CHANGELOG.md](CHANGELOG.md).

+# Building from source
+
+Calendula builds with the standard Android Gradle toolchain — no extra setup
+beyond the SDK and a JDK.
+
+## Requirements
+
+- **Android SDK 36+**
+- **JDK 17** — if your default JDK is not 17, set `JAVA_HOME` explicitly.
+
+The Gradle wrapper is checked in, so you don't need a system Gradle.
+
+## Common tasks
+
+```bash
+./gradlew assembleDebug   # debug APK → app/build/outputs/apk/debug/
+./gradlew test            # JVM unit tests
+./gradlew lint            # Android lint
+```
+
+## Release builds
+
+Release signing and the publishing pipeline are documented separately in
+[RELEASING.md](RELEASING.md).
