+# BfR Glyphosat Image Converter
+
+Use this tool to convert the grayscale images to more readable black/white images.
+These are then combined into a single tiff image and OCR scanned with tesseract to produce a good machine readable form.
+
+The `convert.sh` script does all the nessesary steps and leaves the two files:
+
+* glyphosat_bfr.pdf
+* glyphosat_bfr.txt
+
+# Requirenments
+
+* go (golang)
+* tesseract version 4
+  * german langaue
+* poppler-utils (for `tiffcp`)
+
+# Usage
+
+Place the downloaded glyphosat images in a new directory named `orig` and use the original file names.
+
+Run the convert script: `./convert.sh`
+
+# Hashes
+
+The sha1 and sha256 hashes of the original image files.
