on the read me!!!.txt file step 3. for the issues of java it does not allow me to edit the .bat file.
secondly what does it mean by with a text

quick further explanation: it does not allow me change anything in properties or rename the files. as such I don't know how I am meant to do edits

You edit the bat file using notepad. This is standard for any Minecraft server. I suggest looking up a guide.
