+# Development guide
+
+## Install dependencies via composer
+
+In the project folder run
+
+    $ ./composer.phar install
+
+to install dependencies.
+
+If you add any dependencies in `composer.json` file, run 
+    
+    $ ./composer.phar update
+
+to install new dependencies.
+
+## Directory structure
+
+- `app`: Application code
+- `app/src`: All class files that follow the psr-4 autoloading standard (_see autoload in composer.json_)
+- `app/templates`: Twig template files
+- `config`: Configuration files (_\*.local.php are deployment specific files and ignored by git_)
+- `data/cache/twig`: Twig's autogenerated cache files
+- `data/log`: Log files
+- `public`: Webserver Document root
+- `test`: Unit test files
+- `vendor`: Composer dependencies
+
+## Special files
+
+- `public\index.php`: Appliction entry point
+- `config\{,*.}{global,local}.php`: Configuration files; \*.global.php are loaded first and then can be overriden by \*.local.php
+- `app/dependencies.php`: Wiring dependencies
+- `app/middleware.php`: Application middleware
+- `app/routes.php`: All application routes
+
+## Run it:
+
+1. `$ cd gredu_labs`
+2. `$ php -S 0.0.0.0:8888 -t public public/index.php`
+3. Browse to http://localhost:8888
