+## Introduction
+The abbr module manages Hilbish abbreviations. These are words that can be replaced
+with longer command line strings when entered.
+As an example, `git push` can be abbreviated to `gp`. When the user types
+`gp` into the command line, after hitting space or enter, it will expand to `git push`.
+Abbreviations can be used as an alternative to aliases. They are saved entirely in the history
+Instead of the aliased form of the same command.

+A Snail is a shell script interpreter instance.

+### Methods
+#### dir(path)
+Changes the directory of the snail instance.
+The interpreter keeps its set directory even when the Hilbish process changes
+directory, so this should be called on the `hilbish.cd` hook.
+
+#### run(command, streams)
+Runs a shell command. Works the same as `hilbish.run`, but only accepts a table of streams.

+
+local function doPrompt(fail)
+	hilbish.prompt(lunacolors.format(

+
+We see a whopping **three** Hilbish libraries being used in this part of code.
+First is of course, named after the shell itself, [`hilbish`](../api/hilbish). This is kind of a
+"catch-all" namespace for functions that directly related to shell functionality/settings.
+
+And as we can see, the [hilbish.prompt](../api/hilbish/#prompt) function is used
+to change our prompt. Change our prompt to what, exactly?
+
+The doc for the function states that the verbs `%u` and `%d`are used for username and current directory
+of the shell, respectively. 
+
+We wrap this in the [`lunacolors.format`](../lunacolors) function, to give
+our prompt some nice color.
+
+But you might have also noticed that this is in the `doPrompt` function, which is called once,
+and then used again in a [bait](../api/bait) hook. Specifically, the `command.exit` hook,
+which is called after a command exits, so when it finishes running.
