+##### Maven
+
+You can also use `json-schema-validator` as a dependency in your maven project.
+But Maven cannot use Gradle's metadata so you need to depend on a JVM-specific artifact in your project:
+
+```xml
+<dependency>
+  <groupId>io.github.optimumcode</groupId>
+  <artifactId>json-schema-validator-jvm</artifactId>
+  <version>0.5.1</version>
+</dependency>
+```
+
+And you can also add a sonatype repository to your POM file
+
+```xml
+<repositories>
+  <repository>
+    <id>sonatype-release</id>
+    <name>sonatype-release</name>
+    <url>https://s01.oss.sonatype.org/content/repositories/releases/</url>

+##### Maven
+
+For the Maven you need to add a snapshot repository to your POM file
+
+```xml
+<repositories>
+  <repository>
+    <id>sonatype</id>
+    <name>sonatype-snapshot</name>
+    <url>https://s01.oss.sonatype.org/content/repositories/snapshots/</url>

+    </snapshots>
+    <releases>
+      <enabled>false</enabled>
+    </releases>
+  </repository>
+</repositories>
+```
+
+And then you can add a dependency to a SNAPSHOT version
+
+```xml
+<dependency>
+  <groupId>io.github.optimumcode</groupId>
+  <artifactId>json-schema-validator-jvm</artifactId>
+  <version>0.5.2-SNAPSHOT</version>
