+description: How to let Dapr handle LangGraph Checkpointer (Memory)
+---
+
+The Dapr Python SDK provides integration with LangGraph Checkpointer using the `dapr-ext-langgraph` extension.
+
+## Installation
+
+You can download and install the Dapr LangGraph extension with:
+
+{{< tabpane text=true >}}
+
+{{% tab header="Stable" %}}
+
+```bash
+pip install dapr-ext-langgraph
+```
+
+{{% /tab %}}
+
+{{% tab header="Development" %}}
+{{% alert title="Note" color="warning" %}}
+The development package will contain features and behavior that will be compatible with the pre-release version of the Dapr runtime. Make sure to uninstall any stable versions of the Python SDK extension before installing the `dapr-dev` package.
+{{% /alert %}}
+
+```bash
+pip install dapr-ext-langgraph-dev
+```
+
+{{% /tab %}}
+
+{{< /tabpane >}}
+
+## Example
+
+To let Dapr handle the checkpointer (memory in LangGraph) you only need to utilize the `DaprCheckpointer` as the checkpointer object when compiling the graph. Given the below Component for redis State Manager:
+
+```yaml
+apiVersion: dapr.io/v1alpha1
+kind: Component
+metadata:
+  name: statestore
+spec:
+  type: state.redis
+  version: v1
+  metadata:
+  - name: redisHost
+    value: localhost:6379
+```
+
+You then pass the checkpointer just like any other checkpointer provider:
+
+```python
+from langgraph.graph import StateGraph, MessageState
+from dapr.ext.langgraph import DaprCheckpointer
+
+# Build the graph with nodes and edges
+builder = StateGraph(MessagesState)
+
+memory = DaprCheckpointer(store_name='statestore', key_prefix='dapr')
+graph = builder.compile(checkpointer=memory)
+```
+
+For a full example refer to the [langgraph example]().
