+## Changelog
+
+Release history is in [CHANGELOG.md](CHANGELOG.md).
+
+## Developing
+
+This repository’s sample app depends on `project(":snapnotify")` so `./gradlew check` works on a clean clone without publishing. To validate the same artifact consumers get from Maven, run `./gradlew :snapnotify:publishToMavenLocal` and point a module to `io.github.ivamsi:snapnotify:1.0.6` with `mavenLocal()` in `dependencyResolutionManagement` (or your module repositories).
+
+## Releasing (maintainers)
+
+1. Bump the library version in `snapnotify/build.gradle.kts` (`mavenPublishing { coordinates(...) }`), demo `versionCode` / `versionName`, [CHANGELOG.md](CHANGELOG.md), and the installation/coordinates snippets in this README.
+2. Run `./gradlew check`.
+3. Commit, create an annotated tag `vX.Y.Z`, and push the branch and tag to GitHub.
+4. Publish to Maven Central: `./gradlew :snapnotify:publishAndReleaseToMavenCentral` with [Central Portal credentials and signing](https://vanniktech.github.io/gradle-maven-publish-plugin/central/) (see comments in `gradle.properties`).
+5. On GitHub, create a **Release** from that tag and attach release notes (can mirror the changelog section).
