@@ -9,3 +9,17 @@ This offers a OCR-D compliant workspace processor for some of the functionality
 
 This processor only operates on the text line level and so needs a line segmentation (and by extension a binarized 
 image) as its input.
+
+Example Usage
+-------------
+
+~~~
+ocrd-calamari-recognize -p test-parameters.json -m mets.xml -I OCR-D-SEG-LINE -O OCR-D-OCR-CALAMARI
+~~~
+
+With `test-parameters.json`:
+~~~
+{
+    "checkpoint": "/path/to/some/trained/models/*.ckpt.json"
+}
