 ### Example architectures
+_Note_: For a non-dockerized deployment, first export `DYNAMO_HOME` to point to the dynamo repository root, e.g. `export DYNAMO_HOME=$(pwd)`
 
 #### Aggregated serving
 ```bash
-cd /workspace/examples/llm
+cd $DYNAMO_HOME/examples/llm
 dynamo serve graphs.agg:Frontend -f ./configs/agg.yaml
 ```
 
 #### Aggregated serving with KV Routing
 ```bash
-cd /workspace/examples/llm
+cd $DYNAMO_HOME/examples/llm
 dynamo serve graphs.agg_router:Frontend -f ./configs/agg_router.yaml
