Making the documentation in READ.me more noob friendly

[vinayprabhu]

For Windows using novices:

The 'while true; do ./thyme track -o thyme.json; sleep 30s; done;' will not work in cmd. You will receive the following error message:
'while' is not recognized as an internal or external command,operable program or batch file.

If using MinGW/GitBASH, the ./ is missing.
Hence:

while true; do ./thyme track -o thyme.json; sleep 30s; done;
./thyme show -i thyme.json -w stats > thyme.html
