TL;DR: it's a wiki for any kind of software development tool. The content and its organization are up to the community. Have fun!
Tool TL;DR was created to help people of all levels of expertise get a grasp of the growing software tool landscape. Whether you're a beginner who doesn't know what's out there, or a senior dev who just wants a quick rundown of a particular framework/library/tool, you will find answers here. The explanations are not comprehensive by any means (hence the name), but they provide a quick, clear, and helpful description without having to dig through the documentation. And, if you feel like a particular description could be improved, feel free to edit! Tool TL;DR is, and will always be, a community-first place.
The wiki is broken down by categories and tools. Tools and categories can go in other categories. You can rearrange this structure to find the best fit for information.
Categories have three main parts: the what, why, and where.
The TL;DR of the category. Explain what the category's tools do.
Why is the category of tools is needed in the first place? For those just starting out, this can be valuable when you don't know what you don't know. It also aims to answer why someone would need to start using the type of tool. Again, for those exploring the landscape for the first time, this can provide a great explanation to a question that they didn't even know they might have.
Where, in an application, would the category of tools go? This isn't talking about physical location, instead, you can also think about it like describing a pipeline, each part playing a role at a certain time and place. For example, the Web Server category would describe tools that go (virtually/logically) in front of an Application Server and would be the first in line to handle incoming web traffic. This question exists simply to help people create a mental image of all the pieces in the puzzle.
Some simple guidelines for naming categories:
Tools have one main question: why use this tool over one of its alternatives in the same category?
The tl;dr of the tool. Also describes how the tool deviates from its category's description.
Tools will often have neighbors in the same space, but when exploring what's out there in a TL;DR fashion, you probably want answers as to what separates the tools in a quick and concise way. This section, just like the others, cuts out the jargon and clears up any blurred lines.
There are several other descriptors for tools on their pages.
