+# Model Card for Sprakbanken/trocr_smi_nor
+This is a TrOCR-model for OCR (optical character recognition) of Sámi languages.  
+It can be used to recognize text in images of printed text (scanned books, magazines, etc.) in North Sámi, South Sámi, Lule Sámi, and Inari Sámi.

-## Citation [optional]
 
-<!-- If there is a paper or blog post introducing the model, the APA and Bibtex information for that should go in this section. -->
+## Uses
+You can use the raw model for optical character recognition (OCR) on single text-line images in North Sámi, South Sámi, Lule Sámi, and Inari Sámi. 
 
-**BibTeX:**
+### Out-of-Scope Use
+The model only works with images of lines of text.
+If you have images of entire pages of text, you must segment the text into lines first to benefit from this model.
