+## Build with LangChain and AI in n8n
+With n8n's LangChain nodes you can build AI-powered functionality within your workflows. The LangChain nodes are configurable, meaning you can choose your preferred agent, LLM, memory, and so on. Alongside the LangChain nodes, you can connect any n8n node as normal: this means you can integrate your LangChain logic with other data sources and services.
+
+## Available integrations
+n8n has 200+ different nodes to automate workflows. The list can be found on: https://n8n.io/integrations
