htdocs/lib/elastica/CONTRIBUTING.md

+Contributing
+============
+Help is very welcomed. Code contributions must be done in respect of [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md).
+More details on how to contribute and guidelines for [pull requests](http://elastica.io/contribute/pull-request.html) can be found [here](http://elastica.io/contribute/).
+
+See [Coding guidelines](http://elastica.io/contribute/coding-guidelines.html) for tips on how to do so.
+All changes must be documented in the [CHANGELOG.md](https://github.com/ruflin/Elastica/blob/master/CHANGELOG.md).
+
+
+Issues
+------
+* Bugs & Feature requests: If you found a bug, open an issue on [Github](https://github.com/ruflin/Elastica/issues). Please search for already reported similary issues before opening a new one. You should include code examples (with dependencies if needed) and your Elastica version to the issue description.
+* Questions & Problems: If you have questions or a specific problem, use the [Elastica Gitter](https://gitter.im/ruflin/Elastica) Chat or open an issue on [Stackoverflow](http://stackoverflow.com/questions/tagged/elastica). Make sure to assign the tag Elastica.
+
+
+Setup
+-----
+Elastica currently allows two setups for development. Either through vagrant or docker-compose. To use the vagrant environment, run `vagrant up`. To use the docker environment, check out the Makefile for the necessary commands.
+* Run your changes / tests in the virtual environment to make sure it is reproducible.
+* Run the tests before creating the pull request using vagrant or docker-compose locally.
+
+Commands
+--------
+To run the commands below, you must have docker-compose [installed](https://docs.docker.com/compose/install/). The first time the commands are run it takes some time to download all the partial images. From then on the commands should run very fast. The advantage in using the commands below is that no local tools and libraries have to be installed and it is guaranteed that everytone is using the same tools.
+
+## Run Tests
+
+To run all tests inside the docker environment, run the following command:
+
+```
+make run RUN="make phpunit"
+```
+
+If you want to run just a specific test or a one specific file, run the following command by replacing your file with the existingpath:
+
+```
+ make run RUN="phpunit -c ./test lib/Elastica/Test/SearchTest.php"
+```
+
+## Check style of your code
+This command will call php-cs-fixer with the predefined settings for the elastica project. No local setup of the tools is needed as everything will happen directly in the container.
+```
+make run RUN="make lint"
+```
+
+
+
+
+Coding
+------
+
+### Rules
+* Pull requests are made to master. Changes are never pushed directly (without pull request) into master.
+* We use the Forking Workflow. https://www.atlassian.com/git/tutorials/comparing-workflows/forking-workflow
+* Follow the coding guidelines.
+* Use a feature branch for every pull request. Don't open a pull request from your master branch.
+
+### Pull Requests
+* One change per pull requests: Keep your pull requests as small as possible. Only one change should happen per pull request. This makes it easier to review and provided feedback. If you have a large pull request, try to split it up in multiple smaller requests.
+* Commit messages: Make sure that your commit messages have meaning and provide an understanding on what was changed without looking at the code.
+* Pull requests should be opened as early as possible as pull requests are also here for communication / discussing changes. Add a comment when your pull request is ready to be merged.
+* Tests: Your addition / change must be tested and the builds must be green. Test your changes locally. Add unit tests and if possible functional tests. Don't forget to add the group to your tests. The 4 available groups are @functional, @unit, @shutdown, @benchmark
+* Update the CHANGELOG.md file with your changes
+* Backward Compatibility breaks: In case you break backward compatibility, provide details on why this is needed.
+* Merge: No one should ever merge his own pull request
+
+
+### Name Spaces & Classes
+Most name spaces and classes are self explanotary and use cases can be taken from classes which already exist.
+
+#### Tool Namespace
+The namespace Tool is used for making more complex functionality of Elastica available to the users. In general it maps existing functionality of Elastica and offers simplified functions.
+
+#### Util Class
+The util class is used for all static functions which are used in the Elastica library but don't access the library itself.
