 If you are using version 2.x follow this [guide to migrate Helm to v3](https://helm.sh/docs/topics/v2_v3_migration/#helm)
 
 ### 2. Firstly you need to update helm dependencies by running
 
-    helm dependency update ./helm/api-platform
+```
+helm dependency update ./helm/api-platform
+```
 
 This will create a folder helm/api-platform/charts/ and add all dependencies there.
 Actual this is [bitnami/postgresql](https://bitnami.com/stack/postgresql/helm), a file postgresql-[VERSION].tgz is created.
 
 ### 3. Optional: If you made changes to the Helm chart, check if its format is correct
 
-    helm lint ./helm/api-platform
+```
