        <MarkdownBlock>
            Diagrams lets you draw the cloud system architecture **in Python code**.
        </MarkdownBlock>
        <MarkdownBlock>
            It was born for **prototyping** a new system architecture without any design tools. You can also describe or visualize the existing system architecture as well.
        </MarkdownBlock>
        <MarkdownBlock>
            `Diagram as Code` allows you to **track** the architecture diagram changes in any **version control** system.
        </MarkdownBlock>
        <MarkdownBlock>
            Diagrams currently supports main major providers including: `AWS`, `Azure`, `GCP`, `Kubernetes`, `Alibaba Cloud`, `Oracle Cloud` etc... It also supports `On-Premises` nodes, `SaaS` and major `Programming` frameworks and languages.
        </MarkdownBlock>
        <MarkdownBlock>
            `NOTE: It does not control any actual cloud resources nor does it generate cloud formation or terraform code. It is just for drawing the cloud system architecture diagrams.`
