TR_DEBUG is listed on the Environment Variables wiki, but it just has (undocumented) as a description. I searched commits for the variable and the last mention of it was 599c5a8cc4f26ed9235a09559a5bb2e93afadc6c, which allegedly removed the variable. When searching google and DuckDuckGo I didn't find anything either.

The documentation should probably be updated to remove the reference to TR_DEBU

Merging a few issues into one here.

There seems to be conflicting data on what the "OriginGeopoint" is. In the documentation it's referenced as the location of the PlayerStart while in code it's commented as the coordinates of Unreal level at the coordinates 0,0,0.

Given the immense popularity of Docker and the need to harden it different per platform (see ideas below) - we'd like to start writing a Docker best practices section.

You're welcome to contribute ideas and write best practices - writing and brainstorming will people is an amazing way to deepen your Docker understanding.

At first, we want to collect ideas for best practices, solidify a list

Update various parts of the text.

There's no such thing as "early ReferenceError" anymore (for things like 0++); they're all just "early SyntaxError" now. tc39/ecma262#691

开发者你好，我从使用者的角度对clash的Rule功能和fake-ip功能提出了一些建议，这增加了clash的复杂程度，我不懂编程，不知道实现的困难程度以及系统资源消耗的变化，只是从个人使用中发现的一些问题和需求出发提供一些建议，希望开发者能够参考，如果能采纳就太好了。

一、Rule功能

1、问题

我将clash安装到旁路由openwrt系统中作为透明代理，使用GFW规则模式。

GFW规则模式：MATCH为DIRECT的规则模式，类似：

- DOMAIN-SUFFIX,google.com,Proxy
- DOMAIN-KEYWORD,google,Proxy
- DOMAIN,google.com,Proxy
- MATCH,DIRECT
