+* Personal attacks
+* Trolling or insulting/derogatory comments
+* Public or private harassment
+* Publishing other's private information, such as physical or electronic addresses,
+  without explicit permission
+* Other unethical or unprofessional conduct
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.

 == 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=2.5.4&packaging=jar&jvmVersion=1.8&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=data-mongodb[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 8 (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]
-----
-$ $MONGODB_HOME/bin/mongod --dbpath $MONGODB_HOME/runtime/data --ipv6 --port 27017 --replSet rs0
-...
-"msg":"Successfully connected to host"
-----
-
-Once the MongoDB server starts up, you should see the message (`msg`), "_Successfully connected to host_".
-
-Notice the `--dbpath` option to the `mongod` command. You can set this to anything you like, but in this case, we set
-the absolute path to a sub-directory (`runtime/data/`) under the MongoDB installation directory (in `$MONGODB_HOME`).
-
-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:
-
-[source,bash]
-----
-$ $MONGODB_HOME/bin/mongo
-MongoDB server version: 5.0.0
-...
-----
-
-Then enter the following command:
-
-[source,bash]
-----
-mongo> rs.initiate({ _id: 'rs0', members: [ { _id: 0, host: '127.0.0.1:27017' } ] })
-----
-
-Finally, on UNIX-based system (for example, Linux or Mac OS X) you may need to adjust the `ulimit`.
-In case you need to, you can adjust the `ulimit` with the following command (32768 is just a recommendation):
-
-[source,bash]
-----
-$ ulimit -n 32768
-----
-
-You can use `ulimit -a` again to verify the `ulimit` for "_open files_" was set appropriately.
-
-Now you are ready to build Spring Data MongoDB. Simply enter the following `mvnw` (Maven Wrapper) command:
+You don’t need to build from source to use Spring Data (binaries in https://repo.spring.io[repo.spring.io]), but if you want to try out the latest and greatest, Spring Data can be easily built with the https://github.com/takari/maven-wrapper[maven wrapper].
