Chmod to make executable command

Question

Hey all,
I've done a quick search, but was getting confused with some answers I found, so forgive me if this is answered elsewhere.
I'm trying to install and use the todo.sh shell I found (https://github.com/ginatrapani/todo.txt-cli/wiki/User-Documentation). I'm struggling to get Terminal to recognize "todo.sh" as an executable command. I type:
sh todo.sh
chmod +x todo.sh
and I get no errors. But then when I type todo.sh it returns
-bash: todo.sh: command not found
I even tried running this in a tcsh, and I get the same result. To be honest, I've never actually been able to get chmod to work for me before, even though I've tried a handful of times.
Does anyone have any ideas?
Thanks

ls -l todo.sh
-rwxr-xr-x 1 you staff 277 Dec 17 15:21 todo.sh
The x's above indicate if the file has executable permissions. I'm thinking that chmod did add executable permissions, so most like you do not have the directory containing todo.sh in your PATH environment variable.
You can continue to use the "sh todo.sh" approach, or you can specify a path to the todo.sh
./todo.sh # assumes you are in the directory with todo.sh
# -OR-
$HOME/todo.sh # assumes todo.sh is in your home directory
# -OR-
/full/path/to/todo.sh
You could also modify the PATH environment variable and put the directory with todo.sh in your PATH.
You modify PATH in your .bash_profile (does not exist if you have not created one in the past), or the .profile (bash will choose .bash_profile over .profile, and .profile does not exist unless you created it in the past).
Modifying PATH would be done something like:
nano .bash_profile
and add
export PATH="$PATH:/full/path/to/the/directory"
ONLY You know what /full/path/to/the/directory containing todo.sh is.
