+## Reporting Potential Security Issues
+
+If you have encountered a potential security vulnerability, please **DO NOT** report it on the public
+issue tracker: send it to us at [zf-security@zend.com](mailto:zf-security@zend.com) instead.
+We will work with you to verify the vulnerability and patch it as soon as possible.
+
+When reporting issues, please provide the following information:
+
+- Component(s) affected
+- A description indicating how to reproduce the issue
+- A summary of the security vulnerability and impact
+
+We request that you contact us via the email address above and give the project
+contributors a chance to resolve the vulnerability and issue a new release prior
+to any public exposure; this helps protect users and provides them with a chance
+to upgrade and/or update in order to protect their applications.
+
+For sensitive email communications, please use [our PGP key](http://framework.zend.com/zf-security-pgp-key.asc).
+
+## RUNNING TESTS
+
+> ### Note: testing versions prior to 2.4
+>
+> This component originates with Zend Framework 2. During the lifetime of ZF2,
+> testing infrastructure migrated from PHPUnit 3 to PHPUnit 4. In most cases, no
+> changes were necessary. However, due to the migration, tests may not run on
+> versions < 2.4. As such, you may need to change the PHPUnit dependency if
+> attempting a fix on such a version.
+
+To run tests:
+
+- Clone the repository:
+
+  ```console
+  $ git clone git@github.com:zendframework/zend-json.git
+  $ cd
+  ```
+
+- Install dependencies via composer:
+
+  ```console
+  $ curl -sS https://getcomposer.org/installer | php --
+  $ ./composer.phar install
+  ```
+
+  If you don't have `curl` installed, you can also download `composer.phar` from https://getcomposer.org/
+
+- Run the tests via `phpunit` and the provided PHPUnit config, like in this example:
+
+  ```console
+  $ ./vendor/bin/phpunit
+  ```
+
+You can turn on conditional tests with the phpunit.xml file.
+To do so:
+
+ -  Copy `phpunit.xml.dist` file to `phpunit.xml`
+ -  Edit `phpunit.xml` to enable any specific functionality you
+    want to test, as well as to provide test values to utilize.
+
+## Running Coding Standards Checks
+
+This component uses [php-cs-fixer](http://cs.sensiolabs.org/) for coding
+standards checks, and provides configuration for our selected checks.
+`php-cs-fixer` is installed by default via Composer.
+
+To run checks only:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --dry-run --config-file=.php_cs
+```
+
+To have `php-cs-fixer` attempt to fix problems for you, omit the `--dry-run`
+flag:
+
+```console
+$ ./vendor/bin/php-cs-fixer fix . -v --diff --config-file=.php_cs
+```
+
+If you allow php-cs-fixer to fix CS issues, please re-run the tests to ensure
+they pass, and make sure you add and commit the changes after verification.
+
+## Recommended Workflow for Contributions
+
+Your first step is to establish a public repository from which we can
+pull your work into the master repository. We recommend using
+[GitHub](https://github.com), as that is where the component is already hosted.
+
+1. Setup a [GitHub account](http://github.com/), if you haven't yet
+2. Fork the repository (http://github.com/zendframework/zend-json)
+3. Clone the canonical repository locally and enter it.
+
+   ```console
+   $ git clone git://github.com:zendframework/zend-json.git
+   $ cd zend-json
+   ```
+
+4. Add a remote to your fork; substitute your GitHub username in the command
+   below.
+
+   ```console
+   $ git remote add {username} git@github.com:{username}/zend-json.git
+   $ git fetch {username}
+   ```
+
+### Keeping Up-to-Date
+
+Periodically, you should update your fork or personal repository to
+match the canonical ZF repository. Assuming you have setup your local repository
+per the instructions above, you can do the following:
+
+
+```console
+$ git checkout master
+$ git fetch origin
+$ git rebase origin/master
+# OPTIONALLY, to keep your remote up-to-date -
+$ git push {username} master:master
+```
+
+If you're tracking other branches -- for example, the "develop" branch, where
+new feature development occurs -- you'll want to do the same operations for that
+branch; simply substitute  "develop" for "master".
+
+### Working on a patch
+
+We recommend you do each new feature or bugfix in a new branch. This simplifies
+the task of code review as well as the task of merging your changes into the
+canonical repository.
+
+A typical workflow will then consist of the following:
+
+1. Create a new local branch based off either your master or develop branch.
+2. Switch to your new local branch. (This step can be combined with the
+   previous step with the use of `git checkout -b`.)
+3. Do some work, commit, repeat as necessary.
+4. Push the local branch to your remote repository.
+5. Send a pull request.
+
+The mechanics of this process are actually quite trivial. Below, we will
+create a branch for fixing an issue in the tracker.
+
+```console
+$ git checkout -b hotfix/9295
+Switched to a new branch 'hotfix/9295'
+```
+
+... do some work ...
+
+
+```console
+$ git commit
+```
+
+... write your log message ...
+
+
+```console
+$ git push {username} hotfix/9295:hotfix/9295
+Counting objects: 38, done.
+Delta compression using up to 2 threads.
+Compression objects: 100% (18/18), done.
+Writing objects: 100% (20/20), 8.19KiB, done.
+Total 20 (delta 12), reused 0 (delta 0)
+To ssh://git@github.com/{username}/zend-json.git
+   b5583aa..4f51698  HEAD -> master
+```
+
+To send a pull request, you have two options.
+
+If using GitHub, you can do the pull request from there. Navigate to
+your repository, select the branch you just created, and then select the
+"Pull Request" button in the upper right. Select the user/organization
+"zendframework" as the recipient.
+
+If using your own repository - or even if using GitHub - you can use `git
+format-patch` to create a patchset for us to apply; in fact, this is
+**recommended** for security-related patches. If you use `format-patch`, please
+send the patches as attachments to:
+
+-  zf-devteam@zend.com for patches without security implications
+-  zf-security@zend.com for security patches
+
+#### What branch to issue the pull request against?
+
+Which branch should you issue a pull request against?
+
+- For fixes against the stable release, issue the pull request against the
+  "master" branch.
+- For new features, or fixes that introduce new elements to the public API (such
+  as new public methods or properties), issue the pull request against the
+  "develop" branch.
+
+### Branch Cleanup
+
+As you might imagine, if you are a frequent contributor, you'll start to
+get a ton of branches both locally and on your remote.
+
+Once you know that your changes have been accepted to the master
+repository, we suggest doing some cleanup of these branches.
+
+-  Local branch cleanup
+
+   ```console
+   $ git branch -d <branchname>
+   ```
+
+-  Remote branch removal
+
+   ```console
+   $ git push {username} :<branchname>
+   ```
