## Canonical source

The source of GitLab Community Edition is [hosted on GitLab.com](https://gitlab.com/gitlab-org/gitlab-ce/) and there are mirrors to make [contributing](CONTRIBUTING.md) as easy as possible.

## Open source software to collaborate on code

To see how GitLab looks please see the [features page on our website](https://about.gitlab.com/features/).

- Manage Git repositories with fine grained access controls that keep your code secure
- Perform code reviews and enhance collaboration with merge requests
- Each project can also have an issue tracker and a wiki
- Used by more than 100,000 organizations, GitLab is the most popular solution to manage Git repositories on-premises
- Completely free and open source (MIT Expat license)
- Powered by [Ruby on Rails](https://github.com/rails/rails)

- GitLab Community Edition (CE) is available freely under the MIT Expat license.

## Requirements

Please see the [requirements documentation](doc/install/requirements.md) for system requirements and more information about the supported operating systems.

## Installation

The recommended way to install GitLab is with the [Omnibus packages](https://about.gitlab.com/downloads/) on our package server.
Compared to an installation from source, this is faster and less error prone.
Just select your operating system, download the respective package (Debian or RPM) and install it using the system's package manager.

There are various other options to install GitLab, please refer to the [installation page on the GitLab website](https://about.gitlab.com/installation/) for more information.

You can access a new installation with the login **`root`** and password **`5iveL!fe`**, after login you are required to set a unique password.

## Install a development environment

To work on GitLab itself, we recommend setting up your development environment with [the GitLab Development Kit](https://gitlab.com/gitlab-org/gitlab-development-kit).
If you do not use the GitLab Development Kit you need to install and setup all the dependencies yourself, this is a lot of work and error prone.
One small thing you also have to do when installing it yourself is to copy the example development unicorn configuration file:

    cp config/unicorn.rb.example.development config/unicorn.rb

Instructions on how to start GitLab and how to run the tests can be found in the [development section of the GitLab Development Kit](https://gitlab.com/gitlab-org/gitlab-development-kit#development).
