 # grocy
 ERP beyond your fridge
 
+## Give it a try
+Public demo of the latest version → [https://demo.grocy.info](https://demo.grocy.info) 
+
 ## Motivation
 A household needs to be managed. I did this so far (almost 10 years) with my first self written software (a C# windows forms application) and with a bunch of Excel sheets. The software is a pain to use and Excel is Excel. So I searched for and tried different things for a (very) long time, nothing 100 % fitted, so this is my aim for a "complete houshold management"-thing.
 
 ## What it is about
 For now my main focus is on stock management, ERP your fridge!

 ## How to install
-Just unpack the [latest release](https://github.com/berrnd/grocy/releases/latest) on your PHP (7.0 or later required) enabled webserver (root is the `/public` directory), copy `config-dist.php` to `data/config.php`, edit it to your needs, ensure that the `data` directory is writable and you're ready to go. Alternatively clone this repository and install Composer and Bower dependencies manually.

Default login is user `admin` with password `admin` - the `data/config.php` file. Alternatively clone this repository and install Composer and Bower dependencies manually.
 
 If you use nginx as your webserver, please include `try_files $uri /index.php;` in your location block.
 
-## Notes about barcode readers
-Some fields also allow to select a value by scanning a barcode. It works best when your barcode reader prefixes every barcode with a letter this is normally not part of a item name (I use a `$`) and sends a `TAB` after a scan.

+### Barcode readers
+Some fields also allow to select a value by scanning a barcode. It works best when your barcode reader prefixes every barcode with a letter which is normally not part of a item name (I use a `$`) and sends a `TAB` after a scan.
+
+### Input shorthands for date fields
+For (productivity) reasons all date (and time) input fields use the ISO-8601 format regardless of localization.
+The following shorthands are available:
+- `MMDD` gets expanded to the given day on the current year
+  - Example: `0517` will be converted to `2018-05-17`
+- `DDMMYYYY` gets expanded to the proper ISO-8601 notation
+  - Example: `20190417` will be converted to `2019-04-17`
+- `x` gets expanded to `2099-12-31` (which I use for products which never expire)
+- Down/up arrow keys will increase/decrease the date by one day
+- Right/left arrow keys will increase/decrease the date by 1 week
+
+### Keyboard shorthands for buttons
+Wherever a button contains a bold highlighted letter, this is a shortcut key.
+Example: Button "Add as new **p**roduct" can be "pressed" by using the `P` key on your keyboard.
+
+### Database migrations
+Database schema migration is automatically done when visiting the root (`/`) route (click on the logo in the left upper edge).
+
+### Demo mode
+When the file `data/demo.txt` exists, the application will work in a demo mode which means authentication is disabled and some demo data will be generated during the database schema migration.
