automatically. This can be done by setting the ``TESSDATA_PREFIX`` environment
variable or by passing the path to ``PyTessBaseAPI`` (e.g.:
``PyTessBaseAPI(path='/usr/share/tessdata')``). The path should contain
``.traineddata`` files which can be found at
https://github.com/tesseract-ocr/tessdata.

+ If you need Windows tessocr package and your Python version is not
supported by above mentioned project,
+ you can try to follow `step by step instructions for Windows 64bit` in
`Windows.build.md`_.
+
+ .. _Windows.build.md: Windows.build.md
+
+ tessdata
+ ========
+
+ You may need to point to the tessdata path if it cannot be detected
automatically. This can be done by setting the ``TESSDATA_PREFIX`` environment
variable or by passing the path to ``PyTessBaseAPI`` (e.g.:
``PyTessBaseAPI(path='/usr/share/tessdata')``). The path should contain
``.traineddata`` files which can be found at
https://github.com/tesseract-ocr/tessdata.
+
+ Make sure you have the correct version of traineddata for your
``tesseract --version``.
+
+ You can list the current supported languages on your system using the
``get_languages`` function:
+
+ .. code:: python
+
+ from tesserocr import get_languages
+
+ print(get_languages('/usr/share/tessdata')) # or any other path
that applies to your system
