When adding new "Hello World" programs, please name the file according to the language it was written in, don't abbreviate the language name too much (so use "JavaScript", not "JS") but don't make it TOO long (so use "CSS" not "Cascading Style Sheets". Use hyphens ("-") as word seperators, and only use a single dot (for seperating the filename from the extension). For example, a "Hello World" program in Objective C should be named "Objective-C.m, and the one in HTML should be named HTML.html.
INPORTANT: IF YOU WANT TO CHANGE THE README (README.md), EDIT README_nolist.md (!) THEN RUN THE list_langs.py SCRIPT AS NOTED BELOW.
Use
./list_langs.pyfor updating the list of languages in README.md (make sure you are in the repository's root directory when running the script). This script will completely re-write README.md, copying the contents of README_nolist.md before the listing.
NOTE THAT THIS SCRIPT MUST BE EXECUTED ON PYTHON 3.6+! If your default isn't 3.6+, use python3 list_langs.py.
