# langdata | ||
Source training data for Tesseract for lots of languages | ||
|
||
Want to re-train tesseract for a specific language, by modifying/augmenting the original training data? | ||
Then you have come to the right place! | ||
|
||
If you want to find a language data set to run Tesseract, then look at our | ||
[tessdata repository](https://github.com/tesseract-ocr/tessdata) instead. | ||
|
||
To re-create the training of a single language, _lang,_ you need the following: | ||
* All the data in the _lang_ directory. | ||
* The corresponding unicharset/xheights files for the script(s) used by _lang._ | ||
* All the remaining non-lang-specific files in the top-level directory, such as `font_properties.` | ||
* You also need to obtain the fonts needed to train the language. | ||
Some languages were trained with commercially available fonts, so you will need to buy them in order to | ||
reproduce the training exactly, or use substitutes. |
