 When defining any service in `docker-compose.yml`, you can declare that you are
 extending another service like this:

 This instructs Compose to re-use the configuration for the `webapp` service
 defined in the `common-services.yml` file. Suppose that `common-services.yml`
 looks like this:

@@ -271,103 +263,91 @@ For single-value options like `image`, `command` or `mem_limit`, the new value
 replaces the old value. **This is the default behaviour - all exceptions are
 listed below.**
 
-```yaml
-# original service
-command: python app.py
+    # original service
+    command: python app.py
 
-# local service

+    # result

 In the case of `build` and `image`, using one in the local service causes
 Compose to discard the other, if it was defined in the original service.
 
-```yaml
-# original service
-build: .
+    # original service
+    build: .
 
-# local service
-image: redis

 For the **multi-value options** `ports`, `expose`, `external_links`, `dns` and
 `dns_search`, Compose concatenates both sets of values:
 
-```yaml

-expose:
-  - "3000"

+    expose:
+      - "3000"

+      - "3000"
+      - "4000"
+      - "5000"
 
 In the case of `environment` and `labels`, Compose "merges" entries together
 with locally-defined values taking precedence:
 
-```yaml
-# original service
-environment:
-  - FOO=original
-  - BAR=original
+    # original service
+    environment:

+    environment:
+      - FOO=original

+      - BAZ=local
 
 Finally, for `volumes` and `devices`, Compose "merges" entries together with
 locally-defined bindings taking precedence:
 
-```yaml
-# original service
-volumes:
-  - /original-dir/foo:/foo
-  - /original-dir/bar:/bar
-
-# local service
-volumes:
-  - /local-dir/bar:/bar
-  - /local-dir/baz/:baz
-
-# result
-volumes:
-  - /original-dir/foo:/foo
-  - /local-dir/bar:/bar
-  - /local-dir/baz/:baz
