All the sidebar links can be split into 3 main categories.
The first block of links is designed to achieve the main goal and purpose of the project.
That's why this block is the OpenWrt project and should be placed the first.
It should help users to download firmware and packages, read documentation and get support.
Contribute / Contributing
The second block block is for advanced users and developers who want to contribute to the project by reporting bugs, submitting patches and improving documentation.
About / Info
Technical, legal, contact and supplementary information about the project.
This is a typical about/info block that you can find on many sites across the internet.
