+Introduction to the OrientDB Java APIs
+======================================
+
+This is a simple maven project that shows how to use OrientDB's Java APIs.
+
+### Requirements
+
+- Maven
+- Java 7 or higher
+- OrientDB
+
+### Build
+
+To build and start the server simply type
+
+```bash
+$ mvn clean install
+```
+
+### Run Tests
+
+Before launching unit tests:
+- Install OrientDB
+- Create BaeldungDB, BaeldungDBTwo and BaeldungDBThree databases
+- Uncomment annotations on the test files
