I'm a developer looking into the 'rails' gem on RubyDoc.info. Please find the documentation for the most recent version of 'rails'. From its documentation page, identify the first sentence that describes what Rails is, list the three main layers of its Model-View-Controller (MVC) pattern, and state the command to install Rails if I haven't already.
Navigate to 'https://rubydoc.info/'. Locate the 'Featured Libraries Listing' section on the homepage. Identify the link for the most recent version of the 'rails' gem (e.g., 'rails 8.0.2') and click on it. On the 'rails' documentation page, find the 'What's Rails?' section and extract its first sentence. Identify the three main layers of the MVC pattern as described in the documentation. Locate the 'Getting Started' section and extract the command to install Rails. Synthesize all gathered information into a concise answer.
The agent successfully navigates to the documentation page for the most recent version of 'rails' (e.g., 'rails 8.0.2'). The agent states the first sentence describing Rails as: 'Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.' The agent correctly lists the three main layers of the MVC pattern as: Model, View, and Controller. The agent states the installation command as: 'Install Rails at the command prompt if you haven't yet:' followed by 'gem install rails'.
