+== Running CI tasks locally
+
+Since this pipeline is purely Docker-based, it's easy to:
+
+* Debug what went wrong on your local machine.
+* Test out a a tweak to your test routine before sending it out.
+* Experiment against a new image before submitting your pull request.
+
+All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+
+IMPORTANT: To do this you must have Docker installed on your machine.
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
++
+2. `cd spring-data-mongodb-github`
++
+Next, run the tests from inside the container:
++
+3. `./mvnw clean dependency:list test -Dsort -Dbundlor.enabled=false -B` (or with whatever profile you need to test out)
+
+Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+
+If you need to package things up, do this:
+
+1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
++
+This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
++
+2. `cd spring-data-mongodb-github`
++
+Next, package things from inside the container doing this:
++
+3. `./mvnw clean dependency:list package -Dsort -Dbundlor.enabled=false -B`
+
+NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

-=== MongoTemplate
-
-MongoTemplate is the central support class for Mongo database operations. It provides:
-
-* Basic POJO mapping support to and from BSON
-* Convenience methods to interact with the store (insert object, update objects) and MongoDB specific ones (geo-spatial operations, upserts, map-reduce etc.)
-* Connection affinity callback
-* Exception translation into Spring's https://docs.spring.io/spring/docs/current/spring-framework-reference/html/dao.html#dao-exceptions[technology agnostic DAO exception hierarchy].
-
-=== Spring Data repositories
-
-To simplify the creation of data repositories Spring Data MongoDB provides a generic repository programming model. It will automatically create a repository proxy for you that adds implementations of finder methods you specify on an interface. 
-
-For example, given a `Person` class with first and last name properties, a `PersonRepository` interface that can query for `Person` by last name and when the first name matches a like expression is shown below:
+Here is a quick teaser of an application using Spring Data Repositories in Java:

-=== MongoDB 4.0 Transactions
+[[upgrading]]
+== Upgrading
 
-As of version 4 MongoDB supports https://www.mongodb.com/transactions[Transactions]. Transactions are built on top of
- `ClientSessions` and therefore require an active session.
+Instructions for how to upgrade from earlier versions of Spring Data are provided on the project https://github.com/spring-projects/spring-data-commons/wiki[wiki].
+Follow the links in the https://github.com/spring-projects/spring-data-commons/wiki#release-notes[release notes section] to find the version that you want to upgrade to.
 
-`MongoTransactionManager` is the gateway to the well known Spring transaction support. It allows applications to use
-https://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html[managed transaction features of Spring].
-The `MongoTransactionManager` binds a `ClientSession` to the thread. `MongoTemplate` automatically detects those and operates on them accordingly.
+[[getting-help]]
+== Getting Help
 
-[source,java]
+Having trouble with Spring Data? We’d love to help!
+
+* Check the
+https://docs.spring.io/spring-data/mongodb/docs/current/reference/html/[reference documentation], and https://docs.spring.io/spring-data/mongodb/docs/current/api/[Javadocs].
+* Learn the Spring basics – Spring Data builds on Spring Framework, check the https://spring.io[spring.io] web-site for a wealth of reference documentation.
+If you are just starting out with Spring, try one of the https://spring.io/guides[guides].
+* If you are upgrading, check out the https://docs.spring.io/spring-data/mongodb/docs/current/changelog.txt[changelog] for "`new and noteworthy`" features.
+* Ask a question - we monitor https://stackoverflow.com[stackoverflow.com] for questions tagged with https://stackoverflow.com/tags/spring-data[`spring-data-mongodb`].
+You can also chat with the community on https://gitter.im/spring-projects/spring-data[Gitter].
+* Report bugs with Spring Data MongoDB at https://github.com/spring-projects/spring-data-mongodb/issues[github.com/spring-projects/spring-data-mongodb/issues].
+
+[[reporting-issues]]
+== Reporting Issues
+
+Spring Data uses Github as issue tracking system to record bugs and feature requests.
+If you want to raise an issue, please follow the recommendations below:
+
+* Before you log a bug, please search the https://github.com/spring-projects/spring-data-mongodb/issues[issue tracker] to see if someone has already reported the problem.
+* If the issue does not already exist, https://github.com/spring-projects/spring-data-mongodb/issues/new[create a new issue].
+* Please provide as much information as possible with the issue report, we like to know the version of Spring Data that you are using, the JVM version, Stacktrace, etc.
+* If you need to paste code, or include a stack trace use https://guides.github.com/features/mastering-markdown/[Markdown] code fences +++```+++.
+
+[[guides]]
+== Guides
+
+The https://spring.io/[spring.io] site contains several guides that show how to use Spring Data step-by-step:
+
+* https://spring.io/guides/gs/accessing-data-mongodb/[Accessing Data with MongoDB] is a very basic guide that shows you how to create a simple application and how to access data using repositories.
+* https://spring.io/guides/gs/accessing-mongodb-data-rest/[Accessing MongoDB Data with REST] is a guide to creating a REST web service exposing data stored in MongoDB through repositories.
+
+[[examples]]
+== Examples
+
+* https://github.com/spring-projects/spring-data-examples/[Spring Data Examples] contains example projects that explain specific features in more detail.
+
+[[building-from-source]]
+== Building from Source
+
+You do not need to build from source to use Spring Data. Binaries are available in https://repo.spring.io[repo.spring.io]
+and accessible from Maven using the Maven configuration noted <<maven-configuration,above>>.
+
+NOTE: Configuration for Gradle is similar to Maven.
+
+The best way to get started is by creating a Spring Boot project using MongoDB on https://start.spring.io[start.spring.io].
+Follow this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb[link]
+to build an imperative application and this https://start.spring.io/#type=maven-project&language=java&platformVersion=3.0.0&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb-reactive[link]
+to build a reactive one.
+
+However, if you want to try out the latest and greatest, Spring Data MongoDB can be easily built with the https://github.com/takari/maven-wrapper[Maven wrapper]
+and minimally, JDK 17 (https://www.oracle.com/java/technologies/downloads/[JDK downloads]).
+
+In order to build Spring Data MongoDB, you will need to https://www.mongodb.com/try/download/community[download]
+and https://docs.mongodb.com/manual/installation/[install a MongoDB distribution].
+
+Once you have installed MongoDB, you need to start a MongoDB server. It is convenient to set an environment variable to
+your MongoDB installation directory (e.g. `MONGODB_HOME`).
+
+To run the full test suite, a https://docs.mongodb.com/manual/tutorial/deploy-replica-set/[MongoDB Replica Set]
+is required.
+
+To run the MongoDB server enter the following command from a command-line:
+
+[source,bash]
 ----
-@Configuration
-static class Config extends AbstractMongoConfiguration {
-
-	@Bean
-	MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
-		return new MongoTransactionManager(dbFactory);
-	}
-
-	// ...
-}
-
-@Component
-public class StateService {
-
-	@Transactional
-	void someBusinessFunction(Step step) {
-
-		template.insert(step);
-
-		process(step);
-
-		template.update(Step.class).apply(Update.set("state", // ...
-	};
-});
+$ $MONGODB_HOME/bin/mongod --dbpath $MONGODB_HOME/runtime/data --ipv6 --port 27017 --replSet rs0
+...
+"msg":"Successfully connected to host"
 ----
 
-== Contributing to Spring Data
+Once the MongoDB server starts up, you should see the message (`msg`), "_Successfully connected to host_".
 
-Here are some ways for you to get involved in the community:
+Notice the `--dbpath` option to the `mongod` command. You can set this to anything you like, but in this case, we set
+the absolute path to a sub-directory (`runtime/data/`) under the MongoDB installation directory (in `$MONGODB_HOME`).
 
-* Get involved with the Spring community on Stackoverflow and help out on the https://stackoverflow.com/questions/tagged/spring-data-mongodb[spring-data-mongodb] tag by responding to questions and joining the debate.
-* Create https://jira.spring.io/browse/DATAMONGO[JIRA] tickets for bugs and new features and comment and vote on the ones that you are interested in.
-* Github is for social coding: if you want to write code, we encourage contributions through pull requests from https://help.github.com/forking/[forks of this repository]. If you want to contribute code this way, please reference a JIRA ticket as well covering the specific issue you are addressing.
-* Watch for upcoming articles on Spring by https://spring.io/blog[subscribing] to spring.io.
+You need to initialize the MongoDB replica set only once on the first time the MongoDB server is started.
+To initialize the replica set, start a mongo client:
 
-Before we accept a non-trivial patch or pull request we will need you to https://cla.pivotal.io/sign/spring[sign the Contributor License Agreement]. Signing the contributor’s agreement does not grant anyone commit rights to the main repository, but it does mean that we can accept your contributions, and you will get an author credit if we do. If you forget to do so, you'll be reminded when you submit a pull request. Active contributors might be asked to join the core team, and given the ability to merge pull requests.
+[source,bash]
+----
+$ $MONGODB_HOME/bin/mongo
+MongoDB server version: 6.0.0
+...
+----
 
-== Running CI tasks locally
+Then enter the following command:
 
-Since this pipeline is purely Docker-based, it's easy to:
+[source,bash]
+----
+mongo> rs.initiate({ _id: 'rs0', members: [ { _id: 0, host: '127.0.0.1:27017' } ] })
+----
 
-* Debug what went wrong on your local machine.
-* Test out a a tweak to your test routine before sending it out.
-* Experiment against a new image before submitting your pull request.
+Finally, on UNIX-based system (for example, Linux or Mac OS X) you may need to adjust the `ulimit`.
+In case you need to, you can adjust the `ulimit` with the following command (32768 is just a recommendation):
 
-All of these use cases are great reasons to essentially run what the CI server does on your local machine.
+[source,bash]
+----
+$ ulimit -n 32768
+----
 
-IMPORTANT: To do this you must have Docker installed on your machine.
+You can use `ulimit -a` again to verify the `ulimit` for "_open files_" was set appropriately.
 
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-2. `cd spring-data-mongodb-github`
-+
-Next, run the tests from inside the container:
-+
-3. `./mvnw clean dependency:list test -Dsort -Dbundlor.enabled=false -B` (or with whatever profile you need to test out)
+Now you are ready to build Spring Data MongoDB. Simply enter the following `mvnw` (Maven Wrapper) command:
 
-Since the container is binding to your source, you can make edits from your IDE and continue to run build jobs.
+[source,bash]
+----
+ $ ./mvnw clean install
+----
 
-If you need to package things up, do this:
+If you want to build with the regular `mvn` command, you will need https://maven.apache.org/run-maven/index.html[Maven v3.8.0 or above].
 
-1. `docker run -it --mount type=bind,source="$(pwd)",target=/spring-data-mongodb-github springci/spring-data-openjdk8-with-mongodb-4.0:latest /bin/bash`
-+
-This will launch the Docker image and mount your source code at `spring-data-mongodb-github`.
-+
-2. `cd spring-data-mongodb-github`
-+
-Next, package things from inside the container doing this:
-+
-3. `./mvnw clean dependency:list package -Dsort -Dbundlor.enabled=false -B`
+_Also see link:CONTRIBUTING.adoc[CONTRIBUTING.adoc] if you wish to submit pull requests, and in particular, please sign
+the https://cla.pivotal.io/sign/spring[Contributor’s Agreement] before your first non-trivial change._
 
-NOTE: Docker containers can eat up disk space fast! From time to time, run `docker system prune` to clean out old images.
+=== Building reference documentation
+
+Building the documentation builds also the project without running tests.
+
+[source,bash]
+----
+ $ ./mvnw clean install -Pdistribute
+----
+
+The generated documentation is available from `target/site/reference/html/index.html`.
