-====== Configuring Symfony ======
+====== Configuring Symfony (and Environments) ======
+The main configuration file lives in the app/config/ as a YAML, XML, (and/?) or PHP file. Only YAML is considered here.
+<file yaml app/config/config.yml>
+imports:
+    - { resource: parameters.yml }
+    - { resource: security.yml }
+framework:
+    secret:          "%secret%"
+    router:          { resource: "%kernel.root_dir%/config/routing.yml" }
+    # ...
+# Twig Configuration
+twig:
+    debug:            "%kernel.debug%"
+    strict_variables: "%kernel.debug%"
+# ...
+</file>
 ===== Default Configuration Dump =====
+Dump the default configuration for a bundle in YAML to the console:
+<code bash>
+$ app/console config:dump-reference FrameworkBundle  # using Bundle name
+$ app/console config:dump-reference framework        # using configuration key
+</code>
+===== Environments =====
+Different environments share the same PHP code (apart from the front controller), but use different configuration. A Symfony project generally begins with three environments: ''dev'', ''test'', and ''prod''.
+  * Access ''dev'': http://localhost/app_dev.php/random/10
+  * Access ''prod'': http://localhost/app.php/random/10
+  * The ''test'' environment is used when running automated tests and cannot be accessed directly through the browser. See the [[http://symfony.com/doc/current/book/testing.html|testing chapter]].
+To clear ''prod'' cache, rebuid stuff, etc.:
+<code bash>
+$ php app/console cache:clear --env=prod --no-debug
+</code>
+==== Additional Environments ====
+To create a new environment, copy ''web/app.php'' (or ''web/app_dev.php''?) to a new file and in that file associate the AppKernel with a new environment name in the ''AppKernel'' ctor;
+<code php>
+$kernel = new AppKernel('newname', false);
+</code>
-==== Environments ====
+Then create a config file that matches the environment name but prefixed with ''config_'':
-===== Environment Configuration =====
+<file yaml app/config/config_newname.yml>
+imports:
+    - { resource: config.yml }
+framework:
+    router:   { resource: "%kernel.root_dir%/config/routing_dev.yml" }
+    profiler: { only_exceptions: false }
+# ...
+</file>
