+## Template compatibility
+
+You can define template compatibility with execution platforms and applications using the `engines` property.
+
+This property is a dictionary object, where the execution platform names are the keys, and the [semantic version](https://semver.org/) ranges are the values.
+
+For example, the following `engines` definition specifies that the template is compatible with Camunda 8.6 or higher.
+
+```json
+"engines": {
+  "camunda": ">8.5"
+}
+```
+
+Compatibility is only validated if the platform version is provided by both the template and the modeler. In the example below, the template is compatible with specified versions of both Desktop and Web Modeler, but it requires Camunda version 8.6 or higher for both:
+
+```json
+"engines": {
+  "camunda": ">8.5",
+  "camundaDesktopModeler": ">=5.30",
+  "camundaWebModeler": "^8.5.5"
+}
+```
+
+You can also use this feature to explicitly specify a template’s incompatibility with a platform. For instance, the following template is incompatible with all versions of Web Modeler:
+
+```json
+"engines": {
+  "camundaWebModeler": "0"
+}
+```
+
+If no engines are specified, the template is considered compatible with any execution platform version.
