 To contribute to the development of XTools, you may fork us on GitHub.  A few things to be aware of first:
 
 1. XTools is based on Symfony 3. We use Twig as our template engine.  Symfony is a full MVC system.
-   a. The controllers are located at ``src/AppBundle/controller``.  They are sorted by tool
+   a. The controllers are located at ``src/AppBundle/controller``.  They are sorted by tool.
    b. The twig templates are located at ``app/resources/views``.  They are sorted by tool.
 2. We use the ``@Route`` syntax to configure routes. 
 3. Every tool requires a twig directory and one controller. Also, core parts of XTools require the tool to be registered within `app/config/tools.yml`.
 
 Style Guidelines
-----------------
+================
 
-- It's called "XTools" (with two capital letters).
-- We use 4 spaces to indent code.
-- Opening and closing curly braces must be on their own lines.
-- Variable names are camelCase.  Constants are ALL_CAPS_AND_UNDERSCORES.  Function names are camelCase.
+- It's called "XTools", with two capital letters.
+- XTools conforms to `PSR2`_ coding standards; use ``./vendor/bin/phpcs`` to check your code.
 - Functions and routes must begin with the tool name.
+- Version numbers follow `Semantic Versioning guidelines`_.

 Running Development server
---------------------------
+==========================
+
+First make sure you meet the :ref:`pre-requisites`, and then follow these steps:
 
-Follow these steps
+1. Clone the repository: ``git clone https://github.com/x-tools/xtools-rebirth.git && cd xtools-rebirth``
+2. Run ``composer install`` and answer all the prompts.
+3. Create a new local database: ``./bin/console doctrine:database:create`` (or ``d:d:c``).
+4. Run the database migrations: ``./bin/console doctrine:migrations:migrate`` (or ``d:m:m``)
+5. Launch PHP's built-in server: ``./bin/console server:run`` (or ``s:r``).
+6. Visit ``http://localhost:8000`` in your web browser.
+7. You can stop the server with ``./bin/console server:stop`` (or ``s:s``)
 
-1. Download the repository.
-2. Run ``composer install``
-3. Issue ``php bin/console server:run``.
-4. Visit ``http://localhost:8000`` in your web browser.
+The :ref:`simplecounter` is the simplest tool and should work as soon as you set up XTools.
+Test it by going to http://localhost:8000/sc and put in ``Jimbo Wales`` as the Username and ``en.wikipedia.org`` as the Wiki.
+After submitting you should quickly get results.

+The development server does not cache data; any changes you make are visible after refreshing the page.
+When you edit the ``app/config/parameters.yml`` file, you'll need to clear the cache with ``./bin/console c:c``.
+
+Assets can be dumped with ``./bin/console assetic:dump``,
+and if you're actively editing them you can continually watch for changes with ``./bin/console assetic:watch``.
+
+The logs are in ``var/logs/dev.log``.
+If things are acting up unexpectedly, you might try clearing the cache or restarting the server.
 
 Developing against WMF databases

+Table mappings
+==============
+
+Tool Labs has different versions of tables that utilize indexing to improve performance. We'll want to take advantage of that.
+
+* Go to the config directory with ``cd app/config``
+* Create the file table_map.yml from the template: ``cp table_map.yml.dist table_map.yml``
+* Set the contents of the file to the following::
+
+    parameters:
+      app.table.archive: 'archive_userindex'
+      app.table.revision: 'revision_userindex'
+      app.table.logging: 'logging_logindex'
+
+Sometimes we want <code>logging_userindex</code> and not the logindex. This is handled in the code via the <code>getTableName()</code> function in [https://github.com/x-tools/xtools-rebirth/blob/master/src/Xtools/Repository.php#L144 Repository.php].
