 You can have a huge impact on the project by helping with its code. To contribute code to Caddy, first submit or comment in an issue to discuss your contribution, then open a [pull request](https://github.com/caddyserver/caddy/pulls) (PR). If you're new to our community, that's okay: **we gladly welcome pull requests from anyone, regardless of your native language or coding experience.** You can get familiar with Caddy's code base by using [code search at Sourcegraph](https://sourcegraph.com/github.com/caddyserver/caddy).

 - **[Squash](http://gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html) insignificant commits.** Every commit should be significant. Commits which merely rewrite a comment or fix a typo can be combined into another commit that has more substance. Interactive rebase can do this, or a simpler way is `git reset --soft <diverging-commit>` then `git commit -s`.
 
-- **Be responsible for and maintain your contributions.** Caddy is a growing project, and it's much better when individual contributors help maintain their change after it is merged.
+- **Own your contributions.** Caddy is a growing project, and it's much better when individual contributors help maintain their change after it is merged.
 
 - **Use comments properly.** We expect good godoc comments for package-level functions, types, and values. Comments are also useful whenever the purpose for a line of code is not obvious.
 
-- **Pull requests may still get closed.** The longer a PR stays open and idle, the more likely it is to be closed. If we haven't reviewed it in a while, it probably means the change is not a priority. Please don't take this personally, we're trying to balance a lot of tasks! If nobody else has commented or reacted to the PR, it likely means your change is useful only to you. The reality is this happens quite a lot. We don't tend to accept PRs that aren't generally helpful. For these reasons or others, the PR may get closed even after a review. We are not obligated to accept all proposed changes, even if the best justification we can give is something vague like, "It doesn't sit right." Sometimes PRs are just the wrong thing or the wrong time. Because it is open source, you can always build your own modified version of Caddy with a change you need, even if we reject it in the official repo. Plus, because Caddy is extensible, it's possible your feature could make a great plugin instead!

-- **You certify that you wrote and comprehend the code you submit.** The Caddy project welcomes original contributions that comply with [our CLA](https://cla-assistant.io/caddyserver/caddy), meaning that authors must be able to certify that they created or have rights to the code they are contributing. In addition, we require that code is not simply copy-pasted from Q/A sites or AI language models without full comprehension and rigorous testing. In other words: contributors are allowed to refer to communities for assistance and use AI tools such as language models for inspiration, but code which originates from or is assisted by these resources MUST be:
-
-	- Licensed for you to freely share
-	- Fully comprehended by you (be able to explain every line of code)
-	- Verified by automated tests when feasible, or thorough manual tests otherwise
-
-	We have found that current language models (LLMs, like ChatGPT) may understand code syntax and even problem spaces to an extent, but often fail in subtle ways to convey true knowledge and produce correct algorithms. Integrated tools such as GitHub Copilot and Sourcegraph Cody may be used for inspiration, but code generated by these tools still needs to meet our criteria for licensing, human comprehension, and testing. These tools may be used to help write code comments and tests as long as you can certify they are accurate and correct. Note that it is often more trouble than it's worth to certify that Copilot (for example) is not giving you code that is possibly plagiarised, unlicensed, or licensed with incompatible terms -- as the Caddy project cannot accept such contributions. If that's too difficult for you (or impossible), then we recommend using these resources only for inspiration and write your own code. Ultimately, you (the contributor) are responsible for the code you're submitting.
-
-	As a courtesy to reviewers, we kindly ask that you disclose when contributing code that was generated by an AI tool or copied from another website so we can be aware of what to look for in code review.

 Some security problems are the result of interplay between different components of the Web, rather than a vulnerability in the web server itself. Please only report vulnerabilities in the web server itself, as we cannot coerce the rest of the Web to be fixed (for example, we do not consider IP spoofing, BGP hijacks, or missing/misconfigured HTTP headers a vulnerability in the Caddy web server).
 
-Vulnerabilities caused by misconfigurations are out of scope. Yes, it is entirely possible to craft and use a configuration that is unsafe, just like with every other web server; we recommend against doing that. Similarly, external misconfigurations are out of scope. For example, an open or forwarded port from a public network to a Caddy instance intended to serve only internal clients is not a vulnerability in Caddy.
+Vulnerabilities caused by misconfigurations are out of scope. Yes, it is entirely possible to craft and use a configuration that is unsafe, just like with every other web server; we recommend against doing that.
 
 We do not accept reports if the steps imply or require a compromised system or third-party software, as we cannot control those. We expect that users secure their own systems and keep all their software patched. For example, if untrusted users are able to upload/write/host arbitrary files in the web root directory, it is NOT a security bug in Caddy if those files get served to clients; however, it _would_ be a valid report if a bug in Caddy's source code unintentionally gave unauthorized users the ability to upload unsafe files or delete files without relying on an unpatched system or piece of software.
 
 Client-side exploits are out of scope. In other words, it is not a bug in Caddy if the web browser does something unsafe, even if the downloaded content was served by Caddy. (Those kinds of exploits can generally be mitigated by proper configuration of HTTP headers.) As a general rule, the content served by Caddy is not considered in scope because content is configurable by the site owner or the associated web application.
 
-Security bugs in code dependencies (including Go's standard library) are out of scope. Instead, if a dependency has patched a relevant security bug, please feel free to open a public issue or pull request to update that dependency in our code.

 We consider publicly-registered domain names to be public information. This necessary in order to maintain the integrity of certificate transparency, public DNS, and other public trust systems. Do not redact domain names from your reports. The actual content of your domain name affects Caddy's behavior, so we need the exact domain name(s) to reproduce with, or your report will be ignored.
 
 It will speed things up if you suggest a working patch, such as a code diff, and explain why and how it works. Reports that are not actionable, do not contain enough information, are too pushy/demanding, or are not able to convince us that it is a viable and practical attack on the web server itself may be deferred to a later time or possibly ignored, depending on available resources. Priority will be given to credible, responsible reports that are constructive, specific, and actionable. (We get a lot of invalid reports.) Thank you for understanding.

-            
-            This PR requires **approval from 2+ maintainers** before the tag can be created.

-            ### What happens next?
-            
-            1. Maintainers review this proposal
-            2. When 2+ maintainer approvals are received, an automated workflow will post tagging instructions
-            3. A maintainer manually creates and pushes the signed tag
-            4. The release workflow is triggered automatically by the tag push
-            5. Upon release completion, this PR is closed and the branch is deleted

-	// bogus host; see https://superuser.com/a/925610.) If we disable Host/Origin

-	// so, because:
-	//
-	// 1) Browsers do not allow access to unix sockets
-	// 2) DNS is irrelevant to unix sockets
-	//
-	// If either of those two statements ever fail to hold true, it is not the
-	// fault of Caddy.
-	//
-	// Thus, we do not fill out allowed origins and do not enforce Host
-	// requirements for unix sockets. Enforcing it leads to confusion and

-	// Enforcing host requirements here is effectively security theater,
-	// and a false sense of security.
