 ## Tools
 
 It is possible to validate the docs before bundling them with the following
 command in the `x-pack/plugins/observability/docs/openapi/slo` folder:
 
-  ```bash
-    npx swagger-cli validate entrypoint.yaml
-  ```
+```bash
+  npx swagger-cli validate entrypoint.yaml
+```
 
 Then you can generate the `bundled` files by running the following commands:
 
-  ```bash
-    npx @redocly/cli bundle entrypoint.yaml --output bundled.yaml --ext yaml
-    npx @redocly/cli bundle entrypoint.yaml --output bundled.json --ext json
-  ```
+```bash
+  npx @redocly/cli bundle entrypoint.yaml --output bundled.yaml --ext yaml
+  npx @redocly/cli bundle entrypoint.yaml --output bundled.json --ext json
+```
 
 After generating the json bundle ensure that it is also valid by running the following command:
 
-  ```bash
-     npx @redocly/cli lint bundled.json
-  ```
+```bash
+   npx @redocly/cli lint bundled.json
+```
