 ## Publishing
 To change the live version, update and add files at `/www/sites/qim.compute.dtu.dk/data-repository`. For example, in command line, you can use ssh or sftp to connect to server `thinlinc.compute.dtu.dk` then navigate to `/www/sites/qim.compute.dtu.dk/data-repository` and transfer files.
 
+Known issues: when transfering files, the capitalization of filenames may be inconsistend. E.g. a file named Coal.png will not be changed to coal.png, only the file content is changed, and the link will appear broken.

 Instead of changing your security policy, you can run a local server, e.g. Python’s built-in http server.
