 To make **notes** truly sweet, insert the following into your shell startup file (e.g. `.bash_profile`):  
 `which notes >/dev/null && . "$( notes -i )"`

 #### Notes directory
 The first time you run **notes**, you will be prompted to choose your notes directory. You need to use the **absolute path** to an existing directory. If you ever want to change it, run `notes -d <directory>`.

-Clone this repo, or download and unzip the [tarball](https://github.com/kylebebak/notes/archive/1.0.1.tar.gz). Either add the `bin` directory to your `$PATH`, or create a symlink in your `$PATH` that points to the **notes** executable in the `bin` directory.

 If you execute **notes** via symlink, *make sure that the name of the target file (the symlink) is also notes*. Otherwise, tab completions won't work.
