Joomla! is free and Open Source software distributed under the GNU General Public License version 2 or later.

Looking for an installable package?

Joomla is not installable out of the box from this repository, please use:

For the latest stable package: https://downloads.joomla.org
For a nightly package: https://developer.joomla.org/nightly-builds.html

How to get a working installation from the source

For detailed instructions please visit https://docs.joomla.org/Special:MyLanguage/J5.x:Setting_Up_Your_Local_Environment

You will need:

PHP - basically the same as you need for running a Joomla Site, but you need the cli (command line interface) Version (see https://docs.joomla.org/Special:MyLanguage/Configuring_a_LAMPP_server_for_PHP_development)
Composer - for managing Joomla's PHP Dependencies. For help installing composer please read the documentation at https://getcomposer.org/doc/00-intro.md
Node.js - for compiling Joomla's Javascript and SASS files. For help installing Node.js please follow the instructions available on https://nodejs.org/en/
Git - for version management. Download from here https://git-scm.com/downloads (MacOS users can also use Brew and Linux users can use the built-in package manager, eg apt, yum, etc).

Steps to setup the local environment:

Clone the repository:

git clone https://github.com/joomla/joomla-cms.git

Go to the joomla-cms folder:

cd joomla-cms

Go to the 5.4-dev branch:

git checkout 5.4-dev

Install all the needed composer packages:

composer install

Install all the needed npm packages:

npm ci

Things to be aware of when pulling: Joomla creates a cache of the namespaces of its extensions in JOOMLA_ROOT/administrator/cache/autoload_psr4.php. If extensions are created, deleted or removed in git then this file needs to be recreated. You can simply delete the file and it will be regenerated on the next call to Joomla.

Which branch should my Pull Request target?

Using a simple classification keeps the project stable, transparent, and easy for everyone to contribute.

Type of change	What it means	Target branch
Bug / Patch release	The change fixes an actual error. The software crashes, produces the wrong result, or behaves contrary to its specification. It can be resolved without large‑scale refactoring or new functionality.	5.4-dev (6.0-dev) *
Feature / Minor release	Anything that isn’t a strict bug – new behavior, refactoring, performance improvements, enhancements, UI tweaks, etc. These changes are bundled together for the next minor version.	6.1-dev

* All bugs that already exist in version 5.4.x should be fixed in 5.4-dev. Only bugs that are introduced for the first time in version 6.0.x should target the 6.0-dev branch.

A member of the maintainer or bug squad team confirms the classification and sets the appropriate labels when a PR is opened. If a PR is opened in the wrong branch, a maintainer will simply ask you to retarget it to the proper branch.
