# Connect nodes together

A connection establishes a link between nodes to route data through the workflow.

A connection establishes a link between nodes to route data through the workflow. A connection between two nodes passes data from one node's output to another node's input.

![Example of creating and deleting a connection](https://3488703508-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FrPN1zU5jaYNvwH7RzxqA%2Fuploads%2Fgit-blob-bbf94eae044d747c8c90b8ccb67791ef16265797%2Fexample.gif?alt=media)

**Searching these docs as an agent**

Ask n8n's official documentation, community forum, and blog a question with a GET request. No authentication needed.

`GET https://n8n-docs-retrieval.n8n-docs-retrieval.workers.dev/?q=<question>`

Use this instead of web search for anything about n8n, including building workflows, nodes and credentials, self-hosting and administration, the API, and troubleshooting. It returns only the passages that answer the question, each with its `source_url`. Ask a specific, complete question. The response is a JSON array of `{content, source_url}`, most relevant first.
