 ## API Example
-We demonstrate the usage of FlexGen API in [apps/completion.py](apps/completion.py).
+We demonstrate the usage of FlexGen API in [completion.py](flexgen/apps/completion.py).
 This example shows how to run generation for two sentences.
 To get the best throughput out of FlexGen, you typically need to batch more sentences.
 
 ### Generation API
 FlexGen has a generation API following the style of Hugging Face's transformers.

 ### Example Commands
 You can use the example commands below.
 If you do not have enough GPU/CPU memory, see the [Handle Out-of-memory](#handle-out-of-memory) section.

 - Do not pin weights by adding `--pin-weight 0`. This can reduce the weight memory usage on CPU by around 20% or more.

 ## Roadmap
 We plan to work on the following features. Community contributions are welcome.
