+- Recognize characters in the [i]nput image and [o]utput it in the given file. Put the database ([p]) in `path/to/db_directory` (verify that the folder exists or DB usage will silently be skipped). [m]ode 130 means create + use + extend database:
+
+`gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}}`
+
+- Recognize characters and assume all [C]haracters are numbers:
+
+`gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}} -C "{{0..9}}"`
+
+- Recognize characters with a cert[a]inty of 100% (characters have a higher chance to be treated as unknown):
+
+`gocr -m 130 -p {{path/to/db_directory}} -i {{path/to/input_image.png}} -o {{path/to/output_file.txt}} -a 100`
