-The action defaults to searching for a dependency file (`requirements.txt` for pip or `Pipfile.lock` for pipenv) in the repository, and uses its hash as a part of the cache key. Use `cache-dependency-path` for cases where multiple dependency files are used, they are located in different subdirectories or different files for the hash want to be used.

  - For pip, the action will cache global cache directory
  - For pipenv, the action will cache virtualenv directory
+ - For poetry, the action will cache virtualenv directory
 
 **Please Note:** Restored cache will not be used if the requirements.txt file is not updated for a long time and a newer version of the dependency is available that can lead to an increase in total build time.
 
 The requirements file format allows to specify dependency versions using logical operators (for example chardet>=3.0.4) or specify dependencies without any versions. In this case the pip install -r requirements.txt command will always try to install the latest available package version. To be sure that the cache will be used, please stick to a specific dependency version and update it manually if necessary.
