@@ -4,14 +4,14 @@ With the release of `rust 1.75`, we now require setting the minimal
 `MACOSX_DEPLOYMENT_TARGET` to at least `10.12`. You can do this by appending
 `recipe/conda_build_config.yaml` with the following content:
 
-```
+```yaml
 MACOSX_DEPLOYMENT_TARGET:  # [osx and x86]
   - '10.12'                # [osx and x86]
 ```
 
 You should also add a run dependency on the respective OSX version:
 
-```
+```yaml
   run:
     - __osx >={{ MACOSX_DEPLOYMENT_TARGET|default("10.9") }}  # [osx and x86_64]
 ```
