Activity of rails/rails repository

The rails/rails is a GitHub repository for the Ruby on Rails framework. Ruby on Rails, or simply Rails, is a server-side web application framework written in Ruby under the MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages.

Here's a general overview of the repository:

• License: The Rails source code is released under the MIT License which means that you can use it freely in your projects with very few restrictions.
• Contributors: The repository has a vast number of contributors (over 5000).
• Stars: The repository is exceptionally popular with over 45,000 stars, indicating that many GitHub users value the Rails project.

Some features of this framework include:

• Active Record: Rails introduces the Active Record framework, which saves objects into the database. The Rails version of Active Record identifies the column in a schema and automatically binds data from the schema into a user's object.
• Scaffolding: Rails can automatically create some of the models and views you need for a basic website.
• Convention over Configuration: Rails makes assumptions about what you want to do and how you're going to do it, rather than requiring you to specify details through endless configuration files.

To get started with contributing to the Rails project, you can look at the open issues in the repository, but be sure to also read through the contributing guide and the code of conduct before you start.

Here's a code snippet showing a typical "Hello, world!" in this framework:

Note: This is a vastly simplified example and actual implementation in a Rails application will involve more details.
