+## Build Shannon binary
+
+The `poktrolld` binary is needed to stake your `Gateway` and its delegating `Application`s.
+
+**Retrieve source code and build binaries**
+
+```bash
+mkdir ~/poktroll && cd ~/poktroll
+git clone https://github.com/pokt-network/poktroll.git
+cd poktroll
+make ignite_poktrolld_build
+```
+
+## Create, fund and stake the Gateway and Application accounts
+
+**Create a new key pair for the delegating `Application`**
+
+```bash
+poktrolld keys add application
+```
+
+**Create a new key pair for the `Gateway`**
+
+```bash
+poktrolld keys add gateway
+```
+
+**Fund the Gateway and Application accounts**
+
+Retrieve the `Gateway` and `Application` addresses:
+
+```bash
+echo "Gateway address: $(poktrolld keys show gateway -a)"
+echo "Application address: $(poktrolld keys show application -a)"
+```
+
+Then use the [faucet](https://faucet.testnet.pokt.network/) to fund the `Gateway`
+and `Application` accounts.
+
+**Stake the Gateway**
+
+```bash
+# Create a Gateway stake configuration file
+cat <<EOF > /tmp/stake_gateway
+stake_amount: 1000000upokt
+EOF
+
+poktrolld tx gateway stake-gateway --config=/tmp/stake_gateway --from=gateway --chain-id=poktroll --yes
+
+# OPTIONALLY check the gateway's status
+poktrolld query gateway show-gateway $(poktrolld keys show gateway -a)
+```
+
+**Stake the delegating Application**
+
+```bash
+# Create an Application stake configuration file
+cat <<EOF > /tmp/stake_app
+stake_amount: 10000000upokt
+service_ids:
+  - "0021"
+EOF
+
+poktrolld tx application stake-application --config=/tmp/stake_app --from=application --chain-id=poktroll --yes
+
+# OPTIONALLY check the application's status
+poktrolld query application show-application $(poktrolld keys show application -a)
+```
+
+**Delegate the Application to the Gateway**
+
+```bash
+poktrolld tx application delegate-to-gateway $(poktrolld keys show gateway -a) --from=application --chain-id=poktroll --chain-id=poktroll --yes
+
+# OPTIONALLY check the application's status
+poktrolld query application show-application $(poktrolld keys show application -a)
+```
+
+## Retrieve PATH Gateway source code
+
+Pull the latest `PATH Gateway` source code:
+
+```bash
+mkdir ~/path-gateway && cd ~/path-gateway
+git clone https://github.com/buildwithgrove/path.git
+cd path-gateway
+```
+
+## Generate a PATH Gateway config file for the Shannon network
+
+Run the following command to generate a default Shannon config `cmd/.config.yaml`
+
+```bash
+make copy_shannon_config
+sed -i "s|rpc_url: ".*"|rpc_url: https://shannon-testnet-grove-rpc.beta.poktroll.com|" cmd/.config.yaml
+sed -i "s|host_port: ".*"|host_port: shannon-testnet-grove-grpc.beta.poktroll.com:443|" cmd/.config.yaml
+```
+
+:::note
+
+We aim to setup a `PATH Gateway` with `Centralized Mode` (i.e. The operator owns
+both the `Gateway` and the `Application` accounts).
+
+Refer to [PATH Gateway modes](https://path.grove.city/) for more information.
+<!-- TODO_BETA(red-0ne): Link to PATH Gateway modes documentation once available -->
+
+:::
+
+**Update the `cmd/.config.yaml` file with the `Gateway` and `Application` keys**
+
+```bash
+sed -i '/owned_apps_private_keys_hex:/!b;n;c\      - '"$(yes | poktrolld keys export application --unsafe --unarmored-hex)" cmd/.config.yaml
+sed -i "s|gateway_address: .*|gateway_address: $(poktrolld keys show gateway -a)|" cmd/.config.yaml
+sed -i "s|gateway_private_key_hex: .*|gateway_private_key_hex: $(yes | poktrolld keys export gateway --unsafe --unarmored-hex)|" cmd/.config.yaml
+```
+
+## Build and run the PATH Gateway
+
+```bash
+cd cmd/ && go build -o path . && ./path
+```
+
+You should see the following output:
+
+```json
+{"level":"info","message":"Starting the cache update process."}
+{"level":"warn","message":"endpoint hydrator is disabled: no service QoS generators are specified"}
+{"level":"info","package":"router","message":"PATH gateway running on port 3000"}
+{"level":"warn","error":"buildAppsServiceMap: no apps found.","message":"updateAppCache: error getting the list of apps; skipping update."}
+{"level":"warn","method":"fetchSessions","error":"buildAppsServiceMap: no apps found.","message":"fetchSession: error listing applications"}
+{"level":"warn","message":"updateSessionCache: received empty session list; skipping update."}
+```
+
+Check that the `PATH Gateway` is serving relays:
+
+```bash
+curl http://eth.localhost:3000/v1 \
+    -X POST \
+    -H "Content-Type: application/json" \
+    -d '{"jsonrpc": "2.0", "id": 1, "method": "eth_blockNumber" }'
+```
