+# DicomSeg Generation
+
+## Summary
+The code snippet in the notebook can be used to convert a WKT representation of
+the geometries to a dicomseg file. Note that the script expects the WKT 
+to be formatted with absolute coordinates. Additionally, any invalid geometries 
+should be fixed or removed. 
+You may use the recipes for [coordinate conversion](../coordinate_converter) and 
+fixing invalid geometries for these steps.
+
+### Installation
+No special installation steps required. Follow the virtual environment setup on
+[the main repository page](../README.md#installation) and then follow the steps in the notebook.
