 ```bash
-# In contracts directory
+cd dojo-starter
 sozo build
+sozo migrate
+```
 
-# In new terminal
-katana --disable-fee --allowed-origins "*"
+From the `sozo migrate` command output, find the deployed world address. For example:
+
+```log
+ profile | chain_id | rpc_url
+---------+----------+------------------------
+ dev     | KATANA   | http://localhost:5050/

+🌍 World deployed at block 2 with txn hash: 0x038e984efa3e91e045b33d14e63c5e9f765e5a8fe2b3546fc3ab872f608e37a2
+⛩️   Migration successful with world at address 0x00e2ea9b5dd9804d13903edf712998943b7d5d606c139dd0f13eeb8f5b84da8d

-4. Connect to the development network and indexer
+The world address in this case would be `0x00e2ea9b5dd9804d13903edf712998943b7d5d606c139dd0f13eeb8f5b84da8d`.
+
+4. Run indexer with `torii`
+
+Start the indexer `torii` with the world address from the last step:
 
 ```bash
 # In new terminal
-sozo migrate
+torii --http.cors_origins "*" --world YOUR_WORLD_ADDRESS
+```
+
+The command for the example world address above would be:
+
+```bash
+# Example command only. Use your own world address.
+torii --http.cors_origins "*" --world 0x00e2ea9b5dd9804d13903edf712998943b7d5d606c139dd0f13eeb8f5b84da8d
+```
+
+5. Setup client
+
+```bash
+cd client
+pnpm i
+pnpm dev
 ```
 
-5. Return to the client and refresh the page. You should now see the project connected to the network and indexed!
