-      options:
-        - label: I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
-          required: true
-        - label: I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.
-          required: true
-        - label: I searched issues and did not find any similar issues.

-        ## Configuration and Log Section
-        
-        ### For config
-        Please provide the configuration files that can reproduce the problem, including the server and client.
-        Don't just paste a big exported config file here. Eliminate useless inbound/outbound, rules, options, this can help determine the problem, if you really want to get help.
-
-        ### For logs
-        Please set the log level to debug and dnsLog to true first.
-        Restart Xray-core, then operate according to the reproduction method, try to reduce the irrelevant part in the log.
-        Remember to delete parts with personal information (such as UUID and IP).
-        Provide the log of Xray-core, not the log output by the panel or other things.
-
-        ### Finally
-        After removing parts that do not affect reproduction, provide the actual running **complete** file, do not only provide inbound or outbound or a few lines of logs based on your own judgment.
-        Put the content between the preset ```<details><pre><code>``` ```</code></pre></details>``` in the text box.
-        If the problem is very clear that only related to one end (such as core startup failure/crash after correctly writing the config according to the documents), N/A can be filled in for unnecessary areas below.

-        ### 对于配置文件
-        请提供可以重现问题的配置文件，包括服务端和客户端。
-        不要直接在这里黏贴一大段导出的 config 文件。去掉无用的出入站、规则、选项，这可以帮助确定问题，如果你真的想得到帮助。
-        
-        ### 对于日志
-        请先将日志等级设置为 debug, dnsLog 设置为true.
-        重启 Xray-core ，再按复现方式操作，尽量减少日志中的无关部分。
-        记得删除有关个人信息（如UUID与IP）的部分。
-        提供 Xray-core 的日志，而不是面板或者别的东西输出的日志。
-
-        ### 最后
-        在去掉不影响复现的部分后，提供实际运行的**完整**文件，不要出于自己的判断只提供入站出站或者几行日志。
-        把内容放在文本框预置的 ```<details><pre><code>``` 和 ```</code></pre></details>``` 中间。
-        如果问题十分明确只出现在某一端(如按文档正确编写配置后核心启动失败/崩溃)，可以在下面不需要的项目填入N/A.

-# Note on Distroless Base Image and Architecture Support:
-# - The official 'gcr.io/distroless/static' image provided by Google only supports a limited set of architectures for Linux:
-#   - linux/amd64
-#   - linux/arm/v7
-#   - linux/arm64/v8
-#   - linux/ppc64le
-#   - linux/s390x
-# - Upon inspection, the blob contents of the Distroless images across these architectures are nearly identical, with only minor differences in metadata (e.g., 'Architecture' field in the manifest).
-# - Due to this similarity in content, it is feasible to forcibly specify a single platform (e.g., '--platform=linux/amd64') for unsupported architectures, as the core image content remains compatible with statically compiled binaries like Go applications.

-## Our Pledge
-
-We as members, contributors, and leaders pledge to make participation in our
-community a harassment-free experience for everyone, regardless of age, body
-size, visible or invisible disability, ethnicity, sex characteristics, gender
-identity and expression, level of experience, education, socio-economic status,
-nationality, personal appearance, race, religion, or sexual identity
-and orientation.
-
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
-
-## Our Standards
-
-Examples of behavior that contributes to a positive environment for our
-community include:
-
-* Demonstrating empathy and kindness toward other people
-* Being respectful of differing opinions, viewpoints, and experiences
-* Giving and gracefully accepting constructive feedback
-* Accepting responsibility and apologizing to those affected by our mistakes,
-  and learning from the experience
-* Focusing on what is best not just for us as individuals, but for the
-  overall community
-
-Examples of unacceptable behavior include:
-
-* The use of sexualized language or imagery, and sexual attention or
-  advances of any kind
-* Trolling, insulting or derogatory comments, and personal or political attacks
-* Public or private harassment
-* Publishing others' private information, such as a physical or email
-  address, without their explicit permission
-* Other conduct which could reasonably be considered inappropriate in a
-  professional setting
-
-## Enforcement Responsibilities
-
-Community leaders are responsible for clarifying and enforcing our standards of
-acceptable behavior and will take appropriate and fair corrective action in
-response to any behavior that they deem inappropriate, threatening, offensive,
-or harmful.
-
-Community leaders have the right and responsibility to remove, edit, or reject
-comments, commits, code, wiki edits, issues, and other contributions that are
-not aligned to this Code of Conduct, and will communicate reasons for moderation
-decisions when appropriate.
-
-## Scope
-
-This Code of Conduct applies within all community spaces, and also applies when
-an individual is officially representing the community in public spaces.
-Examples of representing our community include using an official e-mail address,
-posting via an official social media account, or acting as an appointed
-representative at an online or offline event.
-
-## Enforcement
-
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported to the community leaders responsible for enforcement at
-https://t.me/projectXtls.
-All complaints will be reviewed and investigated promptly and fairly.
-
-All community leaders are obligated to respect the privacy and security of the
-reporter of any incident.
-
-## Enforcement Guidelines
-
-Community leaders will follow these Community Impact Guidelines in determining
-the consequences for any action they deem in violation of this Code of Conduct:
-
-### 1. Correction
-
-**Community Impact**: Use of inappropriate language or other behavior deemed
-unprofessional or unwelcome in the community.
-
-**Consequence**: A private, written warning from community leaders, providing
-clarity around the nature of the violation and an explanation of why the
-behavior was inappropriate. A public apology may be requested.
-
-### 2. Warning
-
-**Community Impact**: A violation through a single incident or series
-of actions.
-
-**Consequence**: A warning with consequences for continued behavior. No
-interaction with the people involved, including unsolicited interaction with
-those enforcing the Code of Conduct, for a specified period of time. This
-includes avoiding interactions in community spaces as well as external channels
-like social media. Violating these terms may lead to a temporary or
-permanent ban.
-
-### 3. Temporary Ban
-
-**Community Impact**: A serious violation of community standards, including
-sustained inappropriate behavior.
-
-**Consequence**: A temporary ban from any sort of interaction or public
-communication with the community for a specified period of time. No public or
-private interaction with the people involved, including unsolicited interaction
-with those enforcing the Code of Conduct, is allowed during this period.
-Violating these terms may lead to a permanent ban.
-
-### 4. Permanent Ban
-
-**Community Impact**: Demonstrating a pattern of violation of community
-standards, including sustained inappropriate behavior,  harassment of an
-individual, or aggression toward or disparagement of classes of individuals.
