## Submitting issues

If you have questions about how to install or use Nextcloud, please direct these to our [forum][forum]. We are also available on [IRC][irc].

### Short version

 * The [**issue templates can be found here**][templates] but be aware of the different repositories! See list below. Please always use an issue template when reporting issues.

### Guidelines
* Please search the existing issues first, it's likely that your issue was already reported or even fixed.
  - Go to one of the repositories, click "issues" and type any word in the top search/command bar.
  - You can also filter by appending e. g. "state:open" to the search string.
  - More info on [search syntax within github](https://help.github.com/articles/searching-issues)
* This repository ([server](https://github.com/nextcloud/server/issues)) is *only* for issues within the Nextcloud Server code. This also includes the apps: files, encryption, external storage, sharing, deleted files, versions, LDAP, and WebDAV Auth
* __SECURITY__: Report any potential security bug to us via [our HackerOne page](https://hackerone.com/nextcloud) following our [security policy](https://nextcloud.com/security/) instead of filing an issue in our bug tracker.
* The issues in other components should be reported in their respective repositories: You will find them in our [GitHub Organization](https://github.com/nextcloud/)

* Report the issue using one of our [templates][templates], they include all the information we need to track down the issue.

## Contributing to Source Code

Thanks for wanting to contribute source code to Nextcloud. That's great!

Please read the [Developer Manuals][devmanual] to learn how to create your first application or how to test the Nextcloud code with PHPUnit.

### Tests

In order to constantly increase the quality of our software we can no longer accept pull request which submit un-tested code.
It is a must have that changed and added code segments are unit tested.
In some areas unit testing is hard (aka almost impossible) as of today - in these areas refactoring WHILE fixing a bug is encouraged to enable unit testing.

### Sign your work

We use the Developer Certificate of Origin (DCO) as a additional safeguard
for the Nextcloud project. This is a well established and widely used
mechanism to assure contributors have confirmed their right to license
their contribution under the project's license.
Please read [contribute/developer-certificate-of-origin][dcofile].
If you can certify it, then just add a line to every git commit message:

````
  Signed-off-by: Random J Developer <random@developer.example.org>
````

Use your real name (sorry, no pseudonyms or anonymous contributions).
If you set your `user.name` and `user.email` git configs, you can sign your
commit automatically with `git commit -s`. You can also use git [aliases](https://git-scm.com/book/tr/v2/Git-Basics-Git-Aliases)
like `git config --global alias.ci 'commit -s'`. Now you can commit with
`git ci` and the commit will be signed.

### Apply a license

In case you are not sure how to add or update the license header correctly please have a look at [contribute/HowToApplyALicense.md][applyalicense]
