 ### Running the containers
 ##### Docker-compose
-- NOTLS: Start docker containers by running `docker-compose up -d`. All images will be pulled from Docker Hub.
-- TLS: Start docker containers by running `TLS=1 docker-compose up -d`. All the gRPC communications will be protected by TLS.
-- TLS with spcified ciphersuite: Start docker containers by running `TLS=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 docker-compose up -d`. The available cipher suite can be find at the file [options.go](tls/options.go#L21).
+Start docker containers by running `docker-compose up -d`. All images will be pulled from Docker Hub.
 
-Check if TLS is enabled or not: `docker-compose logs <service> | grep TLS`.
+The workload itself can be configured using optional enviroment variables. The avaialbe configuration items are:
+
+- TLS: Environment variable TLS controls the TLS enablement of gRPC and HTTP communications of the microservices in hotelReservation.
+    - TLS=0 or not set(default): No TLS enabled for gRPC and HTTP communication.
+    - TLS=1: All the gRPC and HTTP communications will be protected by TLS, e.g. `TLS=1 docker-compose up -d`.
+    - TLS=<ciphersuite>: Use specified ciphersuite for TLS, e.g. `TLS=TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 docker-compose up -d`. The avaialbe cipher suite can be found at the file [options.go](tls/options.go#L21).
+
+- GC: Environment variable GC controls the garbage collection target percentage of Golang runtime. The default value is 100. See [golang doc](https://pkg.go.dev/runtime/debug#SetGCPercent) for details.
+
+- JAEGER_SAMPLE_RATIO: Environment variable JAEGER_SAMPLE_RATIO controls the ratio of requests to be traced Jaeger. Default is 0.01(1%).
+
+- MEMC_TIMEOUT: Environment variable MEMC_TIMEOUT controls the timeout value in seconds when communicating with memcached. Default is 2 seconds. We may need to increase this value in case of very high work loads.
+
+- LOG_LEVEL: Environment variable LOG_LEVEL controls the log verbosity. Valid values are: ERROR, WARNING, INFO, TRACE, DEBUG. Default value is INFO.
+
+Users may run `docker-compose logs <service>` to check the corresponding configurations.
