+This example validates the resiliency of the instantiated client and does not 
+demonstrate any extra functionality. It is based off the configuration example 
+to connect to the sidecar and make a call for a configuration item stored in 
+redis. 
+
+1. Insert a key with the value `hello` to redis using the following command:
+
+
+<!-- STEP
+name: Insert test configuration item
+output_match_mode: substring
+expected_stdout_lines:
+  - 'OK'
+background: false
+sleep: 5
+timeout_seconds: 5
+-->
+
+```bash
+docker exec dapr_redis redis-cli MSET hello "world"
+```
+
+<!-- END_STEP -->
+
+2. Run the example without the sidecar
+
+<!-- STEP
+name: Run configuration app
+env:
+  DAPR_GRPC_PORT: "3500"
+  DAPR_API_MAX_RETRIES: "10"
+  DAPR_API_TIMEOUT_MILLISECONDS: "10000"
+output_match_mode: substring
+expected_stdout_lines:
+  - 'Configuration value: ConfigurationItem { value: "world"'
+  - 'Configuration value: ConfigurationItem { value: "world2"'
+background: true
+sleep: 30
+timeout_seconds: 30
+-->
+
+```bash
+cargo run --example resiliency-instance
+```
+
+<!-- END_STEP -->
+
+3. Run the Dapr sidecar
+
+<!-- STEP
+name: Run Dapr sidecar
+output_match_mode: substring
+expected_stdout_lines:
+  - ''
+background: true
+sleep: 10
+timeout_seconds: 10
+-->
+
+```bash
+dapr run --app-id=rustapp --resources-path .../components --dapr-grpc-port 3500
+```
+
+<!-- END_STEP -->
+
+4. Update the hello key with the value `world2` to redis using the following command:
+
+
+<!-- STEP
+name: Update test configuration item
+output_match_mode: substring
+expected_stdout_lines:
+  - 'OK'
+background: false
+sleep: 5
+timeout_seconds: 5
+-->
+
+```bash
+docker exec dapr_redis redis-cli MSET hello "world2"
+```
+
+<!-- END_STEP -->
+
+5. Run the Dapr sidecar (for the second time)
+
+<!-- STEP
+name: Run Dapr sidecar
+output_match_mode: substring
+expected_stdout_lines:
+  - ''
+background: true
+sleep: 10
+timeout_seconds: 10
+-->
+
+```bash
+dapr run --app-id=rustapp --resources-path ../components --dapr-grpc-port 3500
+```
+
+<!-- END_STEP -->
+The example app should make contact with the Dapr sidecar and the result should
+be returned from the configuration request successfully.
+
+```
+Configuration value: ConfigurationItem { value: "world", version: "", metadata: {} }
+```
