Follow this tutorial to set up Git and Gerrit in order to submit patches.
Set up your development environment
You can install and develop MediaWiki on Linux, Windows, or macOS using any of the three solutions below.
Повечето проекти използват Git и Gerrit. Следвайте Урок за Gerrit, за да настроите своя акаунт за програмисти. След това можете да преминете към изтеглянето на нашия код, извършването на промени, тестването им и изпращането на корекции. Има два начина за настройване на вашата среда за разработки: използване на предварително конфигурирана настройка на виртуална машина (Vagrant или Docker) или подход за ръчна конфигурация.
You can also try the experimental mwcli tool which sets up Docker with a few simple commands and provides basic orchestration functionality for MediaWiki Docker containers. With this you can easily add extensions and features to your container.
If you run it from Windows, Docker shares files between your Windows filesystem and the container filesystem. This can cause MediaWiki to be very slow if you are using WSL2 based engine, due to the poor performance of its shared directory implementation. If you have Windows Pro, you can switch to the Hyper-V backend in the settings of Docker Desktop for better filesystem performance.
An even faster way to run MediaWiki using Docker in Windows (speeds comparable to manually installing) is to clone MediaWiki and run Docker inside WSL (or install and run
mwcli inside of WSL).
That way there is no shared filesystem overhead.
To develop the MediaWiki codebase that is inside the Docker container you can establish a remote connection to it and open the MediaWiki WSL folder in that is in the container using VSCode or PhpStorm.
Виртуална машина с Vagrant
Vagrant allows you start a MediaWiki instance you can develop as well as allowing you to add and develop any of 250+ extensions - all with a single command. This saves you installation and configuration time compared to manually installing. It runs faster than Docker on Windows, however slower than Docker on WSL or manually installing.
MediaWiki can be developed by installing it natively on your system and editing its code. Installing it natively means it will run faster than Docker or Vagrant, but it will take more time to configure.

Communication tips and guidelines
Follow these tips to communicate effectively and get help from community members.
Use Phabricator tasks effectively
When you plan to work on a Phabricator task:
- No need to ask for permission: You can work on unassigned tasks without asking someone to assign them to you. There is no authority who assigns tasks or who needs to be asked first.
- If a task already has a recent patch in Gerrit, choose a different task to work on instead.
- If an existing patch in Gerrit has not been merged and has not seen any changes for a long time, you could improve that existing patch, based on the feedback in Gerrit and in the task.
- Do your research: When you consider working on a task, do research before you start coding. Look at the code, try to understand what it is supposed to do, read related documentation, and try to find the places where you need to make code changes.
- In a Phabricator task, use the project tags in the side bar to find the code repository for the task.
- If you have no idea at all how to fix the bug, consider finding an easier one first.
- You do not need to announce your plans before you start working on a task, but you should communicate that you are working on the task.
- When you start work, set yourself as task assignee by clicking Edit Task… in Phabricator, and set your Phabricator username in the Assigned To field. This communicates to others that you are working on it, so they don't duplicate work.
- When your plans or interests change: If you are no longer working on a task, remove yourself as the assignee of the task. This tells others that they can work on the task, and they won't expect you to still work on it.
- Follow Phabricator etiquette.
- In Phabricator tasks, discuss only specific questions about the topic of that task. Don't use Phabricator to ask general questions, like how to set up a development environment or how to fix problems with Gerrit.
Compose good questions
- Don't ask to ask...just ask!.
- Be specific and provide context: Instead of simply asking "Can you give me more info?", "Please guide me", or "Please tell me how to start", include the following information in your question:
- What are you trying to achieve?
- What have you already tried? Copy and paste your commands and their output (if not too long) instead of paraphrasing in your own words.
- What have you found out already during your research? Include links to code, documentation, or other resources you already consulted.
- Use specific titles and subject lines in your communication. "Proposal draft" or "Need help" is not specific.
- Keep conversations readable: When you reply in Zulip, in Phabricator tasks, or on mailing lists, only quote sections of previous comments that are relevant to your response. If you quote a complete previous comment, it makes threads hard to read.
Follow communication policies and best practices
Before you send or post your question:
- Read and follow the code of conduct for Wikimedia technical spaces.
- Use inclusive language: Instead of using terms that assume a gender identity (like "guys", "madam", or "sir") use the name of the person instead.
Ask in the right place
- Ask in public: Do not send private messages if your conversation topic is not secret. Private messages don't help others.
- Ask and discuss in the best place:
- In Phabricator tasks, discuss only specific questions about the topic of that task.
- Ask general technical questions, like how to set up a development environment or how to fix problems with Gerrit, in the places listed on Общуване.
- If you take part in an outreach program, then Zulip is for discussing questions about the outreach programs themselves.
After you post your question:
- Do not ask people for code review in a separate message. People receive Gerrit and Phabricator notifications and will respond when they can.
- When seeking input and comments, especially during weekends and holidays, you may need to wait until business hours resume. On chat channels like IRC: if nobody answers, try again at a different time; don't just give up!
- If you don't get an answer even after waiting and being patient, consider if other Communication channels might be a better place to ask your question.
МедияУики е написан на PHP, така че ще трябва да се запознаете с PHP, за да се справите с основния код на МедияУики.

- The script
maintenance/eval.phpin MediaWiki provides a basic PHP interpreter with MediaWiki objects and classes loaded.
- Also, the script
maintenance/shell.phpin MediaWiki is a replacement of
maintenance/eval.phpbased on PsySH, see Manual:Shell.php
- The script
Many features require some amount of database manipulation, so you'll often need to be familiar with MySQL/MariaDB.
- Ресурси за MySQL/MariaDB
- Неща, които трябва да знаете
- Тествайте кода си с MySQL/MariaDB.
- MediaWiki currently uses MySQL and MariaDB as the primary database back-end. It also supports other DBMSes, such as PostgreSQL and SQLite. However, almost all developers use MySQL/MariaDB and don't test other DBs, which consequently break on a regular basis. You're therefore advised to use MySQL/MariaDB when testing patches, unless you're specifically trying to improve support for another DB. In the latter case, make sure you're careful not to break MySQL/MariaDB (or write queries that are horribly inefficient in it), since MySQL/MariaDB is what everybody else uses.
- Тествайте кода си с MySQL/MariaDB.
The MediaWiki code base is large and some parts are ugly; don't be overwhelmed by it. When you're first starting off, aim to write features or fix bugs which only touch a small region of code.

- Code of Conduct
- MediaWiki runs on most platforms that can support PHP, however, the lack of certain utilities or operating system features may limit the functionality or performance of MediaWiki on non-LAMP platforms.
- MediaWiki has support for DBMS other than MySQL and MariaDB, including PostgreSQL, SQLite
- Developers are a mix of volunteers and paid staff (or contractors) for various organizations. For a full list of who works on the MediaWiki code, read the Developers article.
- Browse the source code and revisions of code repositories at https://phabricator.wikimedia.org/diffusion/ or download the source code to your system by using Gerrit.
