+# Instructions
+
+First, persist your credentials in `~/.aws/credentials` as described in the AWS best practices for persisting credentials, e.g.,
+```
+user@host::~> cat ~/.aws/credentials
+
+[my_profile]
+aws_access_key_id = 3LXXXXXXXXXXXX
+aws_secret_access_key = nuPXXXXXXXXXXXXXXXXXXXXX
+```
+To execute the code example, first adjust the address of the StorageGRID Webscale API Gateway. Then execute:
+```
+$ ./gradlew run
+```
+This will automatically download Gradle and the required libraries. Then, it will compile and execute the example code.
+
+To generate an Eclipse project file, use:
+```
+$ ./gradlew eclipse
+```
+and then choose `File -> Import` in Eclipse, and import the `s3-java` folder.
+
+To run the tests (i.e., to validate other version of the used AWS SDK), run:
+```
+$ ./gradlew test
+```
+
+# Notes
+
+The provided acceptence tests are a quick shot for making sure, that basic functionality works.
