# Add Gateway Gateway is optional and is used only certain use cases where businesses want to expose data sources through a gateway. Gateway requires an Environment created first and if not already done so please visit '[Create an Environment](https://docs.cloudfabrix.io/cfxoia/data-ingestion/how-to-create-an-environment)'. ### How to Add a Gateway: **Step 1**: Select 'Gateways' tab from left side menu. It displays empty screen if no gateway created or existing gateways. **Step 2**: Click on '+' on top right corner menu, to add new gateway. **Step 3**: The following details needs to be filled-in a). Select Environment - Select from the environment to which gateway is attached from the list displayed. b) Gateway IP: Enter gateway IP address. **Step 4**: Click 'Save' to add gateway to the environment. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
