+To avoid specifying the version of each dependency, you can use `BOM` or `Bill Of Materials`.
+
+Using `Maven` you must add the following to `dependencyManagement` section in your `pom.xml`:
+
+```xml tab='Maven'
+<dependencyManagement>
+    <dependencies>
+        <dependency>
+            <groupId>org.testcontainers</groupId>
+            <artifactId>testcontainers-bom</artifactId>
+            <version>{{latest_version}}</version>
+            <type>pom</type>
+            <scope>import</scope>
+        </dependency>
+    </dependencies>
+</dependencyManagement>
+```
+and then use dependencies without specifying a version:
+
+```xml tab='Maven'
+<dependency>
+    <groupId>org.testcontainers</groupId>
+    <artifactId>mysql</artifactId>
+    <scope>test</scope>
+</dependency>
+```
+
+Using `Gradle` you must add the following to `dependencies` section in your `build.gradle`:
+
+```groovy tab='Gradle'
+implementation platform('org.testcontainers:testcontainers-bom:{{latest_version}}') //import bom
+testImplementation('org.testcontainers:mysql') //no version specified
+```
