+Now either you will setup a local testnet or use an existing testnet. If its an existing testnet, you need to fund this account. Send this address to someone who has access to the admin account for your testnet. If you have access yourself you can send funds yourself:
 
 ```

+If you're setting up your own local testnet, continue with the following:

+Before finally starting the node, for it to work with the front end, you need to configure CORS.
+
+In `~/.wasmd/config/config.toml`, you'll need to make sure the listen address binds to the public IP (0.0.0.0) and the CORS allows all origins:
+
+```
+[rpc]
+laddr = "tcp://0.0.0.0:26657" 
+cors_allowed_origins = ["*"]
+```
+
+And in `~/.wasmd/config/app.toml`:
+
+```
+[api]
+enable = true
+address = "tcp://0.0.0.0:1317"
+enabled-unsafe-cors = true
+```
+
+Now, finally:
+
+```
+wasmd start
+```
+
+And you should have a chain making blocks!
+
+You can also reduce the block time by lowering `timeout_commit` in `~/.wasmd/config/config.toml`.
+
+Now that you have the chain running, you can start running the enclave and proxy in other windows.

 ## Run
 
 First set the `NODE_URL` variable to the address of the blockchain node. If it's a local node, set it to `localhost:26657`. If it's a remote node, set it to that node's address (eg. `export NODE_URL=143.244.186.205:26657`).
