+
+Instructions for running the `solana-proxy` using [laconic-so](https://git.vdb.to/cerc-io/stack-orchestrator)
+
+## Setup
+
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/LaconicNetwork/solana-proxy
+  ```
+
+* Build the container image:
+
+  ```bash
+  laconic-so --stack ~/cerc/solana-proxy/stack/stack-orchestrator/stack/solana-proxy build-containers
+  ```
+
+  This should create the `cerc/solana-proxy` image locally
+
+## Create a deployment
+
+* Create a spec file for the deployment:
+
+  ```bash
+  laconic-so --stack ~/cerc/solana-proxy/stack/stack-orchestrator/stack/solana-proxy deploy init --output solana-proxy-spec.yml
+  ```
+
+* Edit `network` in the spec file to map container ports to host ports as required:
+
+  ```bash
+  network:
+    ports:
+      solana-proxy:
+        - '8545:8545'
+  ```
+
+* Create a deployment from the spec file:
+
+  ```bash
+  laconic-so --stack ~/cerc/solana-proxy/stack/stack-orchestrator/stack/solana-proxy deploy create --spec-file solana-proxy-spec.yml --deployment-dir solana-proxy-deployment
+  ```
+
+## Configuration
+
+* Inside the `solana-proxy-deployment` deployment directory, open `config.env` file and set following env variables:
+
+  ```bash
+  # Optional
+  ALCHEMY_API_KEY=your_alchemy_key_here
+  HELIUS_API_KEY=your_helius_key_here
+  QUICKNODE_ENDPOINT=your_endpoint.quiknode.pro
+  QUICKNODE_TOKEN=your_quicknode_token_here
+  LOG_LEVEL=INFO
+  ```
+
+  The proxy will work without API keys using free endpoints, but adding them provides access to premium providers with better rate limits.
+
+## Start the deployment
+
+```bash
+laconic-so deployment --dir solana-proxy-deployment start
+```
+
+The Solana RPC proxy will be available at:
+
+* RPC endpoint: <http://localhost:8545>
+
+* WebSocket endpoint: <ws://localhost:8545/ws>
+
+## Clean up
+
+* Stop the deployment:
+
+  ```bash
+  laconic-so deployment --dir solana-proxy-deployment stop
+  ```
