### Q&A
Q1. I encountered the following problems when using the package manager
```
Executing action: create-project-from-example
CMakeLists.txt not found in project directory /home/username
```
A1. This is because an older version packege manager was used, please run `pip install -U idf-component-manager` in ESP-IDF environment to update.
