 - **Automated Backup Notifications via Email**: Set up a daily database backup and use Pipedream to monitor the completion status of the backup operation. Once a backup is successfully completed, trigger an SMTP action to send an email notification to the system admin, ensuring peace of mind with regular backup status updates.
 
 - **Slack Alerts for High-Value Transactions**: Monitor your MongoDB for transactions exceeding a certain value and send alerts to a Slack channel when such transactions occur. Finance teams can stay on top of significant movements without manual database checks, improving response time and financial oversight.

+# Getting Started
+
+To get started, you need to set up a user to connect to your MongoDB cluster. This guide assumes your MongoDB cluster is hosted on Mongo Atlas.
+
+First, [log in to Mongo Atlas](https://account.mongodb.com/account/login) to complete the next steps.
+
+## Create the MongoDB User
+
+First, create a dedicated user for connecting MongoDB to Pipedream.
+
+Select the MongoDB project where your cluster resides, then select the *Database Access* tab. Here, you'll see a list of users who can connect to your MongoDB cluster.
+
+Click *Create new database user* to get started.
+
+![Open the MongoDB project from within MongoDB Atlas and select the Database Access panel, then create the user](https://res.cloudinary.com/pipedreamin/image/upload/v1715025845/marketplace/apps/mongodb/CleanShot_2024-05-06_at_16.02.42_apamii.png)
+
+In the new pop-up, choose the *Password* authentication method first. Name the user `pipedream` so it’s easy to remember which service this user account is used for.
+
+Generate a password and select a pre-built or custom role. Pre-built roles offer options like read-only or read and write access to all databases in the cluster. For more fine-tuned control, like restricting Pipedream to reading a single database, use a custom role.
+
+Finally click *Add user* to create this new user account.
+
+![Filling out the details of the new user account in MongoDB Atlas for connecting this new user to Pipedream](https://res.cloudinary.com/pipedreamin/image/upload/v1715026023/marketplace/apps/mongodb/CleanShot_2024-05-06_at_16.06.22_rfz4ur.png)
+
+## Provide the Credentials
+
+Now, with a dedicated MongoDB user, connect to Pipedream. Return to Pipedream to set up a new MongoDB action in a workflow or to add your MongoDB account in the Connected Accounts area.
+
+Copy and paste the *Username* and *Password* fields from the previous step, when you created the `pipedream` user in Mongo Atlas.
+
+To find your database hostname, go to the **Databases** view in Mongo Atlas and click the **Connect** button for your chosen database.
+
+Select the **Compass or Node.js** option. Then you’ll see the connection URI string. The hostname is the latter portion of the string, as shown below:

+
+Lastly, provide the **Database** name to connect to.
+
+## Allowing Pipedream Connections
+
+By default, Pipedream workflows can start anywhere within the `us-east-1` AWS IP range. You'll need to expose your MongoDB Atlas Cluster to the internet or use a Pipedream VPC to assign a specific outbound IP address to your workflows.
+
+### Allowing any IP Address Range
+
+First, open the **Network Access** section of your MongoDB Atlas project. Then click **Add new IP address** in the top right-hand corner:
+
+![Add a new IP address to the allowed list of IP addresses within MongoDB Atlas](https://res.cloudinary.com/pipedreamin/image/upload/v1715026727/marketplace/apps/mongodb/CleanShot_2024-05-06_at_16.18.24_a3u6y0.png)
+
+Then enter `0.0.0.0/0` in the IP address field to allow connections from any IP address. In the description field, we recommend adding a note about this requirement for Pipedream.
+
+![Allowing any IP address to connect to your MongoDB Atlas Database Cluster. Necessary for services like Pipedream workflows that don’t have a static IP address unless you’re using Pipedream VPCs.](https://res.cloudinary.com/pipedreamin/image/upload/v1715026860/marketplace/apps/mongodb/CleanShot_2024-05-06_at_16.20.51_ixxmoa.png)
+
+Finally, click **Confirm**
+
+### Using a Pipedream VPC
+
+Pipedream VPCs allow you to define a single static IP address for your workflows and allow you to run these workflows in a separate network.
+
+[Follow this guide to create a VPC and assign the IP address to your workflow.](https://pipedream.com/docs/workflows/vpc)
+
+Then create a new allowed IP address in MongoDB by opening the **Network Access** section in Atlas:
