+# Cook2tex
+
+Two small python scripts that turn [cooklang](https://cooklang.org/) recipes into LaTeX source files.
+The LaTeX files use the [cuisine](https://ctan.org/pkg/cuisine) package.
+
+## cook2tex.py
+
+Takes a recipe path as an argument and returns the cuisine recipe block on stdout.
+
+### Example
+
+`python3 cook2tex.py /path/to/recipe`
+
+## cooklangbook.py
+
+Takes multiple recipe paths as arguments and returns a complete latex document on stdout.
+
+### Example
+
+`python3 cooklangbook.py /path/to/recipes/{rec1,rec2,rec3}`
