   $ laconic-so deploy-system --include db,go-ethereum-foundry,ipld-eth-server,watcher-erc721 up
   ```
 
+## Demo
+
+* Find the watcher container's id using `docker ps` and export it for later use:
+
+  ```bash
+  $ export CONTAINER_ID=<CONTAINER_ID>
+  ```
+
+* Deploy an ERC721 token:
+
+  ```bash
+  $ docker exec $CONTAINER_ID yarn nft:deploy:docker
+  ```
+
+  Export the address of the deployed token to a shell variable for later use:
+
+  ```bash
+  $ export NFT_ADDRESS=<NFT_ADDRESS>
+  ```
+
+* Open `http://localhost:3009/graphql` (GraphQL Playground) in a browser window
+
+* Connect MetaMask to `http://localhost:8545` (with chain ID `99`)
+
+* Export your MetaMask account (second account) address to a shell variable for later use:
+
+  ```bash
+  $ export RECIPIENT_ADDRESS=<RECIPIENT_ADDRESS>
+  ```
+
+* To get the primary account's address, run:
+
+  ```bash
+  $ docker exec $CONTAINER_ID yarn account:docker
+  ```
+
+  Export it to shell variable for later use:
+
+  ```bash
+  $ export PRIMARY_ADDRESS=<PRIMARY_ADDRESS>
+  ```
+
+* To get the current block hash at any time, run:
+
+  ```bash
+  $ docker exec $CONTAINER_ID yarn block:latest:docker
+  ```
+
+* Fire the following GQL query (uses `eth_call`) in the playground:
+
+  ```graphql
+  query {
+    name(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    symbol(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    balanceOf(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+      owner: "PRIMARY_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+  }
+  ```
+
+  Balance for the `PRIMARY_ADDRESS` should be `0` as the token is yet to be minted.
+
+* Fire the following GQL query (uses `storage` calls) in the playground:
+
+  ```graphql
+  query {
+    _name(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    _symbol(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    _balances(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+      key0: "PRIMARY_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+  }
+  ```
+
+* Mint the token:
+
+  ```bash
+  $ docker exec $CONTAINER_ID yarn nft:mint:docker --nft $NFT_ADDRESS --to $PRIMARY_ADDRESS --token-id 1
+  ```
+
+  Fire the GQL query above again with latest block hash. The balance should increase to `1`.
+
+* Get the latest block hash and run the following GQL query in the playground for `balanceOf` and `ownerOf` (`eth_call`):
+
+  ```graphql
+  query {
+    fromBalanceOf: balanceOf(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+      owner: "PRIMARY_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    toBalanceOf: balanceOf(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+      owner: "RECIPIENT_ADDRESS"
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+
+    ownerOf(
+      blockHash: "LATEST_BLOCK_HASH"
+      contractAddress: "NFT_ADDRESS"
+      tokenId: 1
+    ) {
+      value
+      proof {
+        data
+      }
+    }
+  }
+  ```
+
+  Balance should be `1` for the `PRIMARY_ADDRESS`, `0` for the `RECIPIENT_ADDRESS` and owner value of the token should be equal to the `PRIMARY_ADDRESS`.
+
+* Transfer the token:
+
+  ```bash
+  $ docker exec $CONTAINER_ID yarn nft:transfer:docker --nft $NFT_ADDRESS --from $PRIMARY_ADDRESS --to $RECIPIENT_ADDRESS --token-id 1
+  ```
+
+  Fire the GQL query above again with the latest block hash. The token should be transferred to the recipient.
+
+## Clean up
+
+* To stop all the services running in background:
+
+  ```bash
+  $ laconic-so deploy-system --include db,go-ethereum-foundry,ipld-eth-server,watcher-erc721 down
+  ```
