+## Checking out and building
+
+To check out the project and build it from source, do the following:
+
+```
+git clone https://github.com/awspring/spring-cloud-aws.git
+cd spring-cloud-aws
+./mvnw package
+```
+
+To build and install jars into your local Maven cache:
+
+```
+./mvnw install
+```
+
+For faster builds, we recommend using [Maven Daemon](https://github.com/apache/maven-mvnd) and using following commands:
+
+Build:
+
+```
+make build
+```
+
+Clean:
+
+```
+make clean
+```
+
+Format code:
+
+```
+make format
+```
+
+## Building documentation
+
+Documentation can be built by activating the `docs` profile in the maven build.
+
+```
+make docs
+```
+
+It generates:
+
+- reference documentation in `docs/target/generated-docs/`
+- API docs in `target/site/`
