 ## For developers
 
-Developers can use `libtesseract` [C](https://github.com/tesseract-ocr/tesseract/blob/master/api/capi.h) or [C++](https://github.com/tesseract-ocr/tesseract/blob/master/api/baseapi.h) API to build their own application. If you need bindings to `libtesseract` for other programming languages, please see the [wrapper](https://github.com/tesseract-ocr/tesseract/wiki/AddOns#tesseract-wrappers) section on AddOns wiki page.
