Note: If you get an error message (on a linux machine) similar to:
command not found: lume
Check your path by running
echo $PATH
The colon delimited list should have user/local/.deno/bin:$PATH if not you can easily add it by running:
export PATH="/Users/yourUserName/.deno/bin:$PATH" ** remember to put your machine's user name in place of yourUserName
If you still get an error you may need to reinstall by entering this command: deno run -A https://deno.land/x/lume/install.ts
Now, after running echo $PATH you should see .deno/bin in your path list.
