 DocumentDB is compatible with MongoDB, meaning you can use the same MongoDB drivers, applications, and tools to run, manage, and scale workloads on DocumentDB without having to worry about managing the underlying infrastructure.
 
 LocalStack allows you to use the DocumentDB APIs to create and manage DocumentDB clusters and instances.
-The supported APIs are available on our [API coverage page]({{< ref "coverage_docdb" >}}), which provides information on the extent of DocumentDB's integration with LocalStack.

 ### Connect to DocumentDB using Node.js Lambda
 
-{{< callout >}}
+:::note
 You need to set `DOCDB_PROXY_CONTAINER=1` when starting LocalStack to be able to use the returned `Endpoint`, which will be correctly resolved automatically.
 
 The flag `DOCDB_PROXY_CONTAINER=1` changes the default behavior and the container will be started as proxied container.
-Meaning a port from the [pre-defined port]({{< ref "/references/external-ports" >}}) range will be chosen, and when using lambda, you can use `localhost.localstack.cloud` to connect to the instance.

 #### Create the DocDB Cluster with a username and password
 
 We assume you have a `MasterUsername` and `MasterUserPassword` set for DocDB e.g:
-{{< command >}}
-$ awslocal docdb create-db-cluster --db-cluster-identifier test-docdb \
+
+```bash
+awslocal docdb create-db-cluster \

    --engine docdb \
    --master-user-password S3cretPwd! \
    --master-username someuser
-{{< /command >}}
+```
 
 #### Prepare the lambda function
 
 First, we create the zip required for the lambda function with the mongodb dependency.
 You will need [`npm`](https://docs.npmjs.com/) in order to install the dependencies.
 In your terminal run:
 
-{{< command >}}
-$ mkdir resources
-$ cd resources
-$ mkdir node_modules
-$ npm install [email protected]
-{{< /command >}}
+```bash
+mkdir resources
+cd resources
+mkdir node_modules
+npm install [email protected]

 Next, copy the following code into a new file named `index.js` in the `resources` folder:
 
-{{< command >}}
+```javascript
 const AWS = require('aws-sdk');
 const RDS = AWS.RDS;
 const { MongoClient } = require('mongodb');

 Make sure you are inside `resources` directory and run:
-{{< command >}}
-$ zip -r function.zip .
-{{< /command >}}
+
+```bash
+zip -r function.zip .
+```
 
 Finally, we can create the `lambda` function using `awslocal`:
-{{< command >}}
-$ awslocal lambda create-function \
+
+```bash
+awslocal lambda create-function \
   --function-name MyNodeLambda \
   --runtime nodejs16.x \

   --zip-file fileb://function.zip \
   --environment Variables="{DOCDB_CLUSTER_ID=test-docdb,DOCDB_SECRET=S3cretPwd!}"
-{{< /command >}}

 You can invoke the lambda by calling:
-{{< command >}}
-$ awslocal lambda invoke --function-name MyNodeLambda outfile
-{{< /command >}}
+
+```bash
+awslocal lambda invoke \
+  --function-name MyNodeLambda \

 ## Resource Browser
 
 The LocalStack Web Application provides a Resource Browser for managing DocumentDB instances and clusters.
 You can access the Resource Browser by opening the LocalStack Web Application in your browser, navigating to the **Resources** section, and then clicking on **DocumentDB** under the **Database** section.
