+## Run on chainstack dedicated subgraph
 
+After you create an account on [chainstack](https://chainstack.com/), you can deploy this subgraph on their platform.
+
+### 1. Install the graph cli and prepare the environment
+
+```
+yarn global add @graphprotocol/graph-cli
+yarn
+graph codegen subgraph.testnet_fast.yaml  # or subgraph.mainnet_fast.yaml
+```
+
+### 2. Create a new project
+
+You'll need to create a new project on chainstack to contain the subgraph.
+
+### 3. Create a new subgraph
+
+Then go into `Subgraphs` > `Add Subgraph` > `Dedicated Subgraph` 
+Select Ethereum and chose the network you want to deploy on. (Mainnet or Holesky)
+Then `Deploy Subgraph`
+
+### 4. Deploy the subgraph
+
+Copy the `Deployment command` and append the `subgraph.mainnet_fast.yaml` or `subgraph.testnet_fast.yaml` to the command according to the network you want to deploy on.
+
+```
+
+`graph deploy --node https://api.graph-ams.p2pify.com/.../deploy --ipfs https://api.graph-ams.p2pify.com/.../ipfs sgr-190-148-475 subgraph.mainnet_fast.yaml
+`
+```
+### 5. Test the GraphQL request
+
+Wait for the indexing to happen and test the following GraphQL request in the webUI (next to the indexing bar)
+```
+{
+  nexuses {
+    factories {
+      address
+      pools {
+        address
+      }
+    }
+  }
+}
+```
