 == 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].
