# Adding Connectors Choose from our catalogue of connectors and add one to your marketplace. We like starting with one of the following connectors because they have free accounts with sample data in them: * [HubSpot](/kolla/connector-guides/hubspot.md) * [Slack](/kolla/connector-guides/slack.md) Once you have followed the directions at one of the links above, you will have a new connector added to your marketplace. To test the connector you will also need an account with that service to connect to. For example, to test your HubSpot connection, you will need a live HubSpot account with some data in it. Lucky for you, you can [get a free HubSpot account](https://app.hubspot.com/signup-hubspot) with some sample data in it already! --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.getkolla.com/kolla/getting-started/adding-connectors.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
