+# Contributing to Solarium
+
+So you consider contributing to Solarium? That’s great! 
+Here are some pointers to hopefully get a good result.
+
+If you are uncertain about any part or need help please feel free to ask for help.
+
+## Bug reports
+
+* Bugs are intended for problems in the code or missing / faulty documentation. Not for issues with your own environment, questions in how to use feature X etcetera.
+* Include info about your environment: the version of Solarium you are using, PHP version, Solr version
+* If you get a specific error, include as much info as possible. The PHP exception, a Solr error log line, etcetera.
+* When something doesn't work as expected for you, also describe the behaviour you expect.
+* Do a quick search to check if the issue has already been reported
+* Describe your issue well, especially the title. Instead of ‘Select query exception’ use ‘Using a dash in a filterquery tag causes an exception’.
+* Provide steps to reproduce the issue. A unittest is ideal, but a description of manual steps is also very helpful.
+
+## Pull requests
+
+* Your pull requests should target the master branch.
+* A pull request should be mergeable (fast-forward) if not, you will be asked to update it.
+* Ideally any change should include updated or new unittests to cover the changes. You can submit a PR without tests, but it will take longer to merge as someone else will need to fix the test coverage.
+* Solarium follows the Symfony2 code standards: http://symfony.com/doc/current/contributing/code/standards.html
+* Each PR will be checked for code standards violations. Of course anything other than a 'green' status needs to be fixed before a PR can be merged.
+* Each PR will be checked by the CI environment automatically. Of course anything other than a 'green' status needs to be fixed before a PR can be merged.

+# Solarium PHP Solr client library
+
+
+## What is Solarium?
+
+Solarium is a PHP Solr client library that accurately model Solr concepts. Where many other Solr libraries only handle
+the communication with Solr, Solarium also relieves you of handling all the complex Solr query parameters using a
+well documented API.
+
+Please see the docs for a more detailed description.
+
+## Requirements
+
+Solarium only supports PHP 7.0 and up.
+
+It's highly recommended to have Curl enabled in your PHP environment. However if you don't have Curl available you can
+switch from using Curl (the default) to another client adapter. The other adapters don't support all the features of the
+Curl adapter.
+
+## Getting started
+
+The preferred way to install Solarium is by using Composer. Solarium is available on Packagist.
+
+Example:
+```
+ composer require solarium/solarium
+```

+Symfony Contracts
+=================
+
+A set of abstractions extracted out of the Symfony components.
+
+Can be used to build on semantics that the Symfony components proved useful - and
+that already have battle tested implementations.
+
+Design Principles
+-----------------
+
+ * contracts are split by domain, each into their own sub-namespaces;
+ * contracts are small and consistent sets of PHP interfaces, traits, normative
+   docblocks and reference test suites when applicable, etc.;
+ * all contracts must have a proven implementation to enter this repository;
+ * they must be backward compatible with existing Symfony components.
+
+Packages that implement specific contracts should list them in the "provide"
+section of their "composer.json" file, using the `symfony/*-contracts-implementation`
+convention (e.g. `"provide": { "symfony/cache-contracts-implementation": "1.0" }`).
+
+FAQ
+---
+
+### How to use this package?
+
+The abstractions in this package are useful to achieve loose coupling and
+interoperability. By using the provided interfaces as type hints, you are able
+to reuse any implementations that match their contracts. It could be a Symfony
+component, or another one provided by the PHP community at large.
+
+Depending on their semantics, some interfaces can be combined with autowiring to
+seamlessly inject a service in your classes.
+
+Others might be useful as labeling interfaces, to hint about a specific behavior
+that could be enabled when using autoconfiguration or manual service tagging (or
+any other means provided by your framework.)
+
+### How is this different from PHP-FIG's PSRs?
+
+When applicable, the provided contracts are built on top of PHP-FIG's PSRs. But
+the group has different goals and different processes. Here, we're focusing on
+providing abstractions that are useful on their own while still compatible with
+implementations provided by Symfony. Although not the main target, we hope that
+the declared contracts will directly or indirectly contribute to the PHP-FIG.
+
+### Why isn't this package split into several packages?
+
+Putting all interfaces in one package eases discoverability and dependency
+management. Instead of dealing with a myriad of small packages and the
+corresponding matrix of versions, you just need to deal with one package and one
+version. Also when using IDE autocompletion or just reading the source code, it
+makes it easier to figure out which contracts are provided.
+
+There are two downsides to this approach: you may have unused files in your
+`vendor/` directory, and in the future, it will be impossible to use two
+different sub-namespaces in different major versions of the package. For the
+"unused files" downside, it has no practical consequences: their file sizes are
+very small, and there is no performance overhead at all since they are never
+loaded. For major versions, this package follows the Symfony BC + deprecation
+policies, with an additional restriction to never remove deprecated interfaces.

+CHANGELOG
+=========
+
+4.1.0
+-----
+
+ * added support for invokable event listeners tagged with `kernel.event_listener` by default 
+ * The `TraceableEventDispatcher::getOrphanedEvents()` method has been added.
+ * The `TraceableEventDispatcherInterface` has been deprecated.
+
+4.0.0
+-----
+
+ * removed the `ContainerAwareEventDispatcher` class
+ * added the `reset()` method to the `TraceableEventDispatcherInterface`
+
+3.4.0
+-----
+
+  * Implementing `TraceableEventDispatcherInterface` without the `reset()` method has been deprecated.
+
+3.3.0
+-----
+
+  * The ContainerAwareEventDispatcher class has been deprecated. Use EventDispatcher with closure factories instead.
+
+3.0.0
+-----
+
+  * The method `getListenerPriority($eventName, $listener)` has been added to the
+    `EventDispatcherInterface`.
+  * The methods `Event::setDispatcher()`, `Event::getDispatcher()`, `Event::setName()`
+    and `Event::getName()` have been removed.
+    The event dispatcher and the event name are passed to the listener call.
+
+2.5.0
+-----
+
+ * added Debug\TraceableEventDispatcher (originally in HttpKernel)
+ * changed Debug\TraceableEventDispatcherInterface to extend EventDispatcherInterface
+ * added RegisterListenersPass (originally in HttpKernel)
+
+2.1.0
+-----
+
+ * added TraceableEventDispatcherInterface
+ * added ContainerAwareEventDispatcher
+ * added a reference to the EventDispatcher on the Event
+ * added a reference to the Event name on the event
+ * added fluid interface to the dispatch() method which now returns the Event
+   object
+ * added GenericEvent event class
+ * added the possibility for subscribers to subscribe several times for the
+   same event
+ * added ImmutableEventDispatcher

-			Also deleted the iframe removal lines - not necessary it turns out
-
-v1.2.3:		altered jquery 1.1.3.1 broke keyboard access - had to change quite a few things and set display:none on the
-			.superfish rule in CSS instead of top:-999em
-
-v1.3: 		Pretty much a complete overhaul to make all original features work in 1.1.3.1 and above.
-			.superfish rule reverted back to top:-999em (which is better).
-
-v1.3.1:		altered 'li[ul]' to $('li:has(ul)') to work with jQuery 1.2
-
-v1.3.2: 	added onshow callback option as requested - 'this' keyword refers to revealed ul.
-			fixed bug whereby multiple menus on a page shared options. Now each menu can have separate options.
-			fixed IE6 and IE7 bug whereby under certain circumstances => 3rd tier menus appear instantly with text missing when revisited
-
-v1.3.3: 	altered event attachment selectors for performance increase on menu setup.
-
-v1.3.4: 	fixed pathClass bug as current path was not being restored. Still doesn't if using keyboard nav (will work on that).
-
-v1.4: 		store options objects in array $.superfish.o. Also provide public access to $.superfish.defaults
-			provided backward compat for jQuery versions less than 1.2 via oldJquery option - will use li[ul] or li:has(ul) as needed
-			added more callbacks, also added option to disable hoverIntent usage if that plugin is detected
-
-v1.4.1: 	fixed current path not being restored when using keyboard to tab away from the menu completely
-			optimised code further - now less code
-			removed addself() in favour of backward compatible add(this)
-			also remove new mouseenter/mouseleave events on window.unload (due to paranoia)
-
-v1.4.2:		3rd July 2008. added semi-colon at start of superfish.js file to avert script concatenation errors
-			added pathLevels option to limit the depth of submenus that get restored by pathClass
-			CSS of main example hugely simplified - other example CSS files less-so.
-				- top level menu items are not fixed width
-				- only need to set submenu widths in one place.
-				- various other improvements.
-				- class names used in all CSS files are changed to be less generic
-			released optional Supersubs plugin which dynamically adjusts submenu widths
-			attach everything to jQuery.fn.superfish to clean up jQuery namespace
-			removed the multi-tier-all-horizontal-example as it was never a great idea and doesn't seem to be in use
-			Update documentation text and remove certain caveats which were there to support users of much older versions of Superfish
-			Documentation now show how to apply bgIgrame 2.1 - it's much easier than before
-			Add all links and their focus and blur events to the onunload unbind - paranoid about memory leaks
-
-v1.4.3		5th July 2008. documentation completely redone using Mike Alsup's templates.
-			CSS revised so that all types of menu use superfish.css as a base. Include additional CSS files to acheive alternate styles.
-			class="sf-menu sf-vertical" creates vertical menu, class="sf-menu sf-navbar" creates nav-bar style menu
-
-v1.4.4		7th July 2008. arrows feature added. If option 'autoArrows' is true, auto-appends (spans) to anchors that have a ul submenu sibling,
-			and adds class 'sf-with-ul' to anchor.
-			CSS added to style new arrows, including an 8-bit alpha (NOT INDEXED!) transparent png of arrow - degrades to solid for IE6.
-			Manually add arrow mark-up to docs and disable autoArrows (via defaults option) to maintain decent performance (for docs page)
-			Update docs, including zip download, to suit.
-			Fix CSS bug that had the third tier of the navbar-style menu visible when JS not available.
-			
-v1.4.5		9 July 2008. decreased code weight
-			added drop shadows for capable browsers - added css and 8-bit alpha transparent png image for shadow
-			remove support for jQuery v<1.2
-			remove unload clean-up which was there to solve garbage collection problems in early jQuery versions
-			remove toggling 'visibility' on hide and show which as a fix for an IE bug that is no longer exhibited
-			removed need for getOpts, rewrote getMenu
-			use [].join('') instead of string concatenation for performance increase - probably very slight in this case
-			change selector in 'over' function from '.'+o.hoverClass to 'li.'+o.hoverClass
-
-v1.4.6		added workaround for IE7 shadows. If animation alters opacity then shadow is hidden during the animation and appears after.
-			This required some JS and a line of CSS, so created shortcut references to lighten code further.
-			
-v1.4.7		added back in the visibility toggle that was removed in 1.4.5 as the bug is indeed still exhibited by IE6 & 7
-			tweaked the look of the shadow slightly and use nicer 32bit png as I now find they behave the same as 8bit png with regard to fades in IE7
-			
-v1.4.8		fix over-sight: using 32bit png meant that the shadow image did show in IE6. Rather than go back to 8bit, add code to exclude IE6 from getting shadow class.
-			use new folder structure recommended by Matt from TopicTrack, for easier updates.
