+Add the following dependency to your `pom.xml`:
+
+```xml
+
+<dependency>
+    <groupId>org.mvnsearch</groupId>
+    <artifactId>dotenvx-spring-boot-starter</artifactId>
+    <version>0.1.0</version>
+</dependency>
+```
+
 Start your Spring Boot application, and add `-Ddotenv.private.key=your_private_key` to the command line,
 and dotenvx start will automatically decrypt the `encrypted:` prefixed items in your properties or YAML files.
