 This script can be used, to extract points from a altidude containing TIFF file -- e.g. for species distribution if you only have unprecise locality data.
 
 ## How to use
+**This is WIP and not implemented yet**
+
 Execute this script in your parent directory, where each species should have its own subdirectory containing the shapefiles for the dots. Every folder will be processed consecutively.
 
 The altitude TIFF `CHELSA-DEM.tif` should be in the same directory.
