    Woe to you if you delete `home.php` or `404.php`, as those are assumed to exist for fallback behavior.

    If you don't know what this is about, or you don't have it, you need to read up on Composer.  Right now.
 
 ### Files
-* settings.template.php
+* settings.template.php  
    App configuration.  Copy to `settings.php` and customize.  Documented with inline comments.
-* required.php
+* required.php  
    The "duct tape" that holds the app together.  Use `require_once __DIR__."/required.php"` at the top of every file.  
    It loads Composer dependencies, app settings, language data, and creates `$database` for accessing the database.  
    It also has some utility functions, including `dieifnotloggedin()`, `is_empty($var)`, and `lang('key')`.  
    Read through it to see what those functions do.
-* action.php
+* action.php  
    A good place to post forms to.  By default it only handles logging out, but is easily expanded.
-* index.php
+* index.php  
    Login page and handler.  Hands off to `app.php` after authenticating user.  
    It includes 2fa support, by the way.
-* app.php
+* app.php  
    Main app page after login.  Handles loading app pages and 404 errors.  
    Redirects to `index.php` if the user is not logged in.  
    Note: to show an alert message (success, error, whatever), set the GET argument `msg` to a message ID from `lang/messages.php`.
-* pages.php
+* pages.php  
-   Define app pages/screens in an array.  The page ID/array key is assumed to exist as a file `pages/{key}.php`, or it will 404.

       `'icon' => '...'` will show an icon from FontAwesome in the menu bar.  Setting this to `home` will show the icon `fa-home`.
-* lang/messages.php
+* lang/messages.php  
    Array of alert messages.
    `"string"` is the language string for the message, `"type"` is one of `success`, `info`, `warning`, or `danger`.
    Changing the type changes the icon and color of the alert box.
-*lang/en_us.php
+*lang/en_us.php  
    Language data for US English.
-*lib/login.php
+*lib/login.php  
    Functions for logging in users and stuff like that.  Mostly makes requests to the Portal API, which calls the real functions "over there".
