-= Spring Session
-Rob Winch
+Spring Session provides an API and implementations for managing a user's session information, while also making it trivial to support clustered sessions without being tied to an application container specific solution.
+It also provides transparent integration with:
 
-Spring Session aims to provide a common infrastructure for managing sessions. This provides many benefits including:
+* `HttpSession` - allows replacing the `HttpSession` in an application container (i.e. Tomcat) neutral way, with support for providing session IDs in headers to work with RESTful APIs.
+* `WebSocket` - provides the ability to keep the `HttpSession` alive when receiving WebSocket messages
+* `WebSession` - allows replacing the Spring WebFlux's `WebSession` in an application container neutral way.
 
-* Accessing a session from any environment (i.e. web, messaging infrastructure, etc)
-* In a web environment
-** Support for clustering in a vendor neutral way
-** Pluggable strategy for determining the session id
-** Easily keep the HttpSession alive when a WebSocket is active
+== Modules
+
+This Spring Session repository consists of the following modules:
+
+* Spring Session Core - provides core Spring Session functionalities and APIs
+* Spring Session Data Redis - provides `SessionRepository` and `ReactiveSessionRepository` implementation backed by Redis and configuration support
+* Spring Session JDBC - provides `SessionRepository` implementation backed by a relational database and configuration support
+* Spring Session Hazelcast - provides `SessionRepository` implementation backed by Hazelcast and configuration support
+* Spring Session MongoDB - provides `SessionRepository` implementation backed by MongoDB and configuration support
+
+Additional Spring Session modules can be found in the https://github.com/spring-projects/spring-session-data-geode[spring-session-data-geode] repository.
+
+== Getting Started
+
+We recommend you visit the https://docs.spring.io/spring-session/docs/current/reference/html5/#samples[Spring Session Reference] and look through the "Samples and Guides" section to see which one best suits your needs.
+
+== Samples
+
+Spring Session samples are available in the https://github.com/spring-projects/spring-session/tree/main/spring-session-samples[spring-session-samples] directory.
+
+
+== Contributing
+
+Please see our https://github.com/spring-projects/spring-session/blob/main/CONTRIBUTING.adoc[Contributing guidelines]
+for information on how to report issues, enhancements or security vulnerabilities.
+
+== Building from Source
+
+Spring Session uses a https://gradle.org[Gradle]-based build system.
+In the instructions below, `./gradlew` is invoked from the root of the source tree and serves as
+a cross-platform, self-contained bootstrap mechanism for the build.
+
+Check out sources
+----
+git clone git@github.com:spring-projects/spring-session.git
+----
+
+Install all spring-\* jars into your local Maven cache
+----
+./gradlew install
+----
+
+Compile and test; build all jars, distribution zips, and docs
+----
+./gradlew build
+----
+
+
+== Documentation
+
+You can find the documentation, samples, and guides for using Spring Session on the https://projects.spring.io/spring-session/[Spring Session project site].
+
+For more in depth information, visit the https://docs.spring.io/spring-session/reference/[Spring Session Reference].

+== 1. Update Dependencies
+
+Dependencies are declared in `gradle/dependency-management.gradle`.
+Update Spring Framework, Spring Security and Spring Data at a minimum.
+
+Run all the checks:
+
+[source,bash]
+----
+$ ./gradlew check
+----
+
+Create separate issues for each dependency update, aside from test dependencies which can be combined into a single commit.
+
+== 2. Check All Issues are Closed
+
+You can manually check at https://github.com/spring-projects/spring-session/milestones
+
+== 3. Update Release Version
+
+Update the version number in `gradle.properties` for the release, for example `3.0.0-M1`, `3.0.0-RC1`, `3.0.4`
+
+== 4. Update Antora Version
+
+You will need to update the antora.yml version.
+
+For milestone / release candidate releases you should follow this format:
+----
+version: '3.0.0-RC1'
+prerelease: 'true'
+display_version: '3.0.0-RC1'
+----
+
+== 5. Build Locally
+
+Run the build using
+
+[source,bash]
+----
+$ ./gradlew check
+----
+
+== 6. Push the Release Commit
+
+Push the commit and GitHub actions will build and deploy the artifacts.
+Wait for the artifact to appear in https://repo1.maven.org/maven2/org/springframework/session/spring-session-core/
+
+== 7. Tag the release
+
+Tag the release and then push the tag
+
+....
+git tag 3.0.0-RC1
+git push origin 3.0.0-RC1
+....
+
+== 8. Update to Next Development Version
+
+Update `gradle.properties` version to next `+SNAPSHOT+` version, update antora.yml and then push
+
+== 9. Update version on project pages
+
+Update the versions on https://spring.io/projects for Spring Session Core, Spring Session Data Redis, Spring Session JDBC, Spring Session Hazelcast, and Spring Session MongoDB.
+
+== 10. Update Release Notes on GitHub
+
+Download
+https://github.com/spring-io/github-changelog-generator/releases/latest[the
+GitHub release notes generator]
+
+* Generate the release notes
+
+....
+java -jar github-changelog-generator.jar \
+    --changelog.repository=spring-projects/spring-session \
+    $MILESTONE release-notes
+....
+
+Note 1: `+$MILESTONE+` is something like `+3.0.4+` or `+3.0.0-M1+`. +
+Note 2: This will create a file on your filesystem
+called `+release-notes+`.
+
+* Copy the release notes to your clipboard (your mileage may vary with
+the following command)
+
+....
+cat release-notes | xclip -selection clipboard
+....
+
+* Create the
+https://github.com/spring-projects/spring-session/releases[release on
+GitHub], associate it with the tag, and paste the generated notes.
+
+== 11. Close / Create Milestone
+
+* In
+https://github.com/spring-projects/spring-session/milestones[GitHub
+Milestones], create a new milestone for the next release version.
+* Move any open issues from the existing milestone you just released to
+the new milestone.
+* Close the milestone for the release.
+
+Note: Spring Session typically releases only one milestone (M1) and one release candidate (RC1).
+
+== 12. Announce the release
+
+* Announce via Slack on https://pivotal.slack.com/messages/spring-session[#spring-session], and tag any downstream Spring Session projects (e.g Spring Session for Apache Geode).
+
+Note: Do not post on #spring-release or create a blog post. Those steps happen after the Spring Session BOM is released.
