> Once you have [configured the Redash permissions](/apps/connectors/business-intelligence/redash/how-tos/set-up-redash), you can establish a connection between Atlan and Redash.

Once you have [configured the Redash permissions](https://docs.atlan.com/llms/connectors/redash/set-up-redash/llms.txt), you can establish a connection between Atlan and Redash.

To crawl metadata from Redash, review the [order of operations](https://docs.atlan.com/llms/catalog/connector-capabilities/order-workflows/llms.txt) and then complete the following steps.

## Select the source

To select Redash as your source:

1. In your Atlan workspace, click **Connectors** in the left sidebar.
 * If you are using the **Old UI (Classic)**, click **New Workflow** in the top navigation.

2. Click **Marketplace**.

3. Search for **Redash Assets** and select it.

4. Click **Install**.

5. Once installation completes, click **Setup Workflow** on the same tile.

## Provide your credentials

To enter your Redash credentials:

1. For _Host Name_, enter the URL for your Redash instance.

2. For _Authentication_, _API Key_ is the default selection.

3. For _API Key_, enter the [API key you copied](https://docs.atlan.com/llms/connectors/redash/set-up-redash/llms.txt) from your Redash instance.

4. Click the **Test Authentication** button to confirm connectivity to Redash.

5. Once authentication is successful, navigate to the bottom of the screen and click **Next**.

## Configure the connection

To complete the Redash connection configuration:

1. Provide a _Connection Name_ that represents your source environment. For example, you might use values like `production`,`development`,`gold`, or `analytics`.

2. (Optional) To change the users who are able to manage this connection, change the users or groups listed under _Connection Admins_.

 :::warning

 If you do not specify any user or group, no one will be able to manage the connection - not even admins.

 :::

3. Navigate to the bottom of the screen and click **Next** to proceed.

## Configure the crawler

Before running the Redash crawler, you can further configure it.

On the _Metadata_ page, you can override the defaults for any of these options:

- To select the queries with tags you want to include in crawling, click **Include queries with tags**. (This will default to all assets, if none are specified.)
- To select the queries with tags you want to exclude from crawling, click **Exclude queries with tags**. (This will default to no assets, if none are specified.)
- To select the dashboards with tags you want to include in crawling, click **Include dashboards with tags**. (This will default to all assets, if none are specified.)
- To select the dashboards with tags you want to exclude from crawling, click **Exclude dashboards with tags**. (This will default to no assets, if none are specified.)
- For _Advanced Config_, you can either keep **Default** to allow default options for asset inclusion or click **Custom** to further configure the crawler:
 - For _Include unpublished queries_, click **Yes** to enable crawling unpublished queries or **No** to skip crawling them.
 - For _Include queries without tags_, click **Yes** to enable crawling queries without tags or **No** to skip crawling them.
 - For _Include dashboards without tags_, click **Yes** to enable crawling dashboards without tags or **No** to skip crawling them.
 - For _Alternate Host URL_, enter the protocol and host name to be used for viewing your assets directly in Redash from Atlan. If added, the _View in Redash_ option will redirect to the alternate host URL instead of the [host URL used to run the crawler](https://docs.atlan.com/llms/connectors/redash/crawl-redash/llms.txt).

:::info **Did you know?** 
 If an asset appears in both the include and exclude filters, the exclude filter takes precedence.

## Run the crawler

To run the Redash crawler, after completing the steps above:

1. To check for any [permissions or other configuration issues](https://docs.atlan.com/llms/connectors/redash/preflight-checks-for-redash/llms.txt) before running the crawler, click **Preflight checks**.

2. You can either:
 - To run the crawler once immediately, at the bottom of the screen, click the **Run** button.
 - To schedule the crawler to run hourly, daily, weekly, or monthly, at the bottom of the screen, click the **Schedule Run** button.

Once the crawler has completed running, you will see the assets on Atlan's asset page! 🎉
