 # Full-text extraction not supported
 
 For some distributions we do not provide the required dependencies for full-text extraction of attachments. If you need this feature, please install the required dependencies (`catdoc unrtf poppler-utils tesseract-ocr`) manually. For more information, [please see the plaintext gem](https://github.com/planio-gmbh/plaintext). Once installed, check `Administration > Information` to see if OpenProject is able to pick up these dependencies.
