All Qubes OS documentation pages are stored as plain text files in the
dedicated [qubes-doc](https://github.com/QubesOS/qubes-doc) repository. By
cloning and regularly pulling from this repo, users can maintain their own
up-to-date offline copy of all Qubes documentation rather than relying solely
on the web.

## Security
*Also see: [Should I trust this website?](/faq/#should-i-trust-this-website)*
All pull requests (PRs) against [qubes-doc](https://github.com/QubesOS/qubes-doc) must pass review prior to be merged, except in the case of [external documentation](/doc/#external-documentation) (see [#4693](https://github.com/QubesOS/qubes-issues/issues/4693)).
This process is designed to ensure that contributed text is accurate and non-malicious.
This process is a best effort that should provide a reasonable degree of assurance, but it is not foolproof.
For example, all text characters are checked for ANSI escape sequences.
However, binaries, such as images, are simply checked to ensure they appear or function the way they should when the website is rendered.
They are not further analyzed in an attempt to determine whether they are malicious.

Once a pull request passes review, the reviewer should add a signed comment stating, "Passed review as of `<latest_commit>`" (or similar).
The documentation maintainer then verifies that the pull request is mechanically sound (no merge conflicts, broken links, ANSI escapes, etc.).
If so, the documentation maintainer then merges the pull request, adds a PGP-signed tag to the latest commit (usually the merge commit), then pushes to the remote.
In cases in which another reviewer is not required, the documentation maintainer may review the pull request (in which case no signed comment is necessary, since it would be redundant with the signed tag).

A few notes before we get started:
* Since Qubes is a security-oriented project, every documentation change will be reviewed before it's accepted.
This allows us to maintain quality control and protect our users.
* We don't want you to spend time and effort on a contribution that we can't accept.
If your contribution would take a lot of time, please [file an issue](/doc/reporting-bugs/) for it first so that we can make sure we're on the same page before significant works begins.
* Alternatively, you may already have written content that doesn't conform to these guidelines, but you'd be willing to modify it so that it does.
In this case, you can still submit it by following the instructions below.
Just make a note in your pull request (PR) that you're aware of the changes that need to be made and that you're just asking for the content to be reviewed before you spend time making those changes.

## Organizational guidelines
### Do not duplicate documentation
Duplicating documentation is almost always a bad idea.
There are many reasons for this.
The main one is that almost all documentation has to be updated as some point.
When similar documentation appears in more than one place, it is very easy for it to get updated in one place but not the others (perhaps because the person updating it doesn't realize it's in more than once place).
When this happens, the documentation as a whole is now inconsistent, and the outdated documentation becomes a trap, especially for novice users.
Such traps are often more harmful than if the documentation never existed in the first place.
The solution is to **link** to existing documentation rather than duplicating it.
There are some exceptions to this policy (e.g., information that is certain not to change for a very long time), but they are rare.

### Core vs. external documentation
Core documentation resides in the [Qubes OS Project's official repositories](https://github.com/QubesOS/), mainly in [qubes-doc](https://github.com/QubesOS/qubes-doc).
External documentation can be anywhere else (such as forums, community websites, and blogs), but there is an especially large collection in the [Qubes Community](https://github.com/Qubes-Community) project.
External documentation should not be submitted to [qubes-doc](https://github.com/QubesOS/qubes-doc).
If you've written a piece of documentation that is not appropriate for [qubes-doc](https://github.com/QubesOS/qubes-doc), we encourage you to submit it to the [Qubes Community](https://github.com/Qubes-Community) project instead.
However, *linking* to external documentation from [qubes-doc](https://github.com/QubesOS/qubes-doc) is perfectly fine.
Indeed, the maintainers of the [Qubes Community](https://github.com/Qubes-Community) project should regularly submit PRs against the documentation index (see [How to edit the documentation index](#how-to-edit-the-documentation-index)) to add and update Qubes Community links in the "External Documentation" section of the documentation table of contents.

The main difference between **core** (or **official**) and **external** (or **community** or **unofficial**) documentation is whether it documents software that is officially written and maintained by the Qubes OS Project.
The purpose of this distinction is to keep the core docs maintainable and high-quality by limiting them to the software output by the Qubes OS Project.
In other words, we take responsibility for documenting all of the software we put out into the world, but it doesn't make sense for us to take on the responsibility of documenting or maintaining documentation for anything else.
For example, Qubes OS may use a popular Linux distribution for an official [TemplateVM](/doc/templates/).
However, it would not make sense for a comparatively small project like ours, with modest funding and a lean workforce, to attempt to document software belonging to a large, richly-funded project with an army of paid and volunteer contributors, especially when they probably already have documentation of their own.
This is particularly true when it comes to Linux in general.
Although many users who are new to Qubes are also new to Linux, it makes absolutely no sense for our comparatively tiny project to try to document Linux in general when there is already a plethora of documentation out there.

Many contributors do not realize that there is a significant amount of work involved in *maintaining* documentation after it has been written.
They may wish to write documentation and submit it to the core docs, but they see only their own writing process and fail to consider that it will have to be kept up-to-date and consistent with the rest of the docs for years afterward.
Submissions to the core docs also have to go through a review process to ensure accuracy before being merged (see [security](#security)), which takes up valuable time from the team.
We aim to maintain high quality standards for the core docs (style and mechanics, formatting), which also takes up a lot of time.
If the documentation involves anything external to the Qubes OS Project (such as a website, platform, program, protocol, framework, practice, or even a reference to a version number), the documentation is likely to become outdated when that external thing changes.
It's also important to periodically review and update this documentation, especially when a new Qubes release comes out.
Periodically, there may be technical or policy changes that affect all the core documentation.
The more documentation there is relative to maintainers, the harder all of this will be.
Since there are many more people who are willing to write documentation than to maintain it, these individually small incremental additions amount to a significant maintenance burden for the project.

On the positive side, we consider the existence of community documentation to be a sign of a healthy ecosystem, and this is quite common in the software world.
The community is better positioned to write and maintain documentation that applies, combines, and simplifies the official documentation, e.g., tutorials that explain how to install and use various programs in Qubes, how to create custom VM setups, and introductory tutorials that teach basic Linux concepts and commands in the context of Qubes.
In addition, just because the Qubes OS Project has officially written and maintains some flexible framework, such as `qrexec`, it does not make sense to include every tutorial that says "here's how to do something cool with `qrexec`" in the core docs.
Such tutorials generally also belong in the community documentation.

Subdividing the page into clearly-labeled sections for each version has several benefits:
Subdividing the page into clearly-labeled sections for each version has several
benefits:
* It preserves good content for older (but still supported) versions.
Many documentation contributors are also people who prefer to use the latest version.
Many of them are tempted to *replace* existing content that applies to an older, supported version with content that applies only to the latest version.
This is somewhat understandable.
Since they only use the latest version, they may be focused on their own experience, and they may even regard the older version as deprecated, even when it's actually still supported.
However, allowing this replacement of content would do a great disservice to those who still rely on the older, supported version.
In many cases, these users value the stability and reliability of the older, supported version.
With the older, supported version, there has been more time to fix bugs and make improvements in both the software and the documentation.
Consequently, much of the documentation content for this version may have gone through several rounds of editing, review, and revision.
It would be a tragedy for this content to vanish while the very set of users who most prize stability and reliability are depending on it.
* It's easy for readers to quickly find the information they're looking for, since they can go directly to the section that applies to their version.
* It's hard for readers to miss information they need, since it's all in one place.
In the incorrect example, information that the reader needs could be in any paragraph in the entire document, and there's no way to tell without reading the entire page.
In the correct example, the reader can simply skim the headings in order to know which parts of the page need to be read and which can be safely ignored.
The fact that some content is repeated in the two version-specific sections is not a problem, since no reader has to read the same thing twice.
Moreover, as one version gets updated, it's likely that the documentation for that version will also be updated.
Therefore, content that is initially duplicated between version-specific sections will not necessarily stay that way, and this is a good thing:
We want the documentation for a version that *doesn't* change to stay the same, and we want the documentation for a version that *does* change to change along with the software.
* It's easy for documentation contributors and maintainers to know which file to edit and update, since there's only one page for all Qubes OS versions.
Initially creating the new headings and duplicating content that applies to both is only a one-time cost for each page, and many pages don't even require this treatment, since they apply to all currently-supported Qubes OS versions.
* It preserves good content for older (but still supported) versions. Many
documentation contributors are also people who prefer to use the latest

to an older, supported version with content that applies only to the latest

the headings in order to know which parts of the page need to be read and
which can be safely ignored. The fact that some content is repeated in the
two version-specific sections is not a problem, since no reader has to read
the same thing twice. Moreover, as one version gets updated, it's likely that
the documentation for that version will also be updated. Therefore, content
that is initially duplicated between version-specific sections will not
necessarily stay that way, and this is a good thing: We want the
documentation for a version that *doesn't* change to stay the same, and we
want the documentation for a version that *does* change to change along with
the software.
* It's easy for documentation contributors and maintainers to know which file
to edit and update, since there's only one page for all Qubes OS versions.
Initially creating the new headings and duplicating content that applies to
both is only a one-time cost for each page, and many pages don't even require
this treatment, since they apply to all currently-supported Qubes OS
versions.
By contrast, an alternative approach, such as segregating the documentation into two different branches, would mean that contributions that apply to both Qubes versions would only end up in one branch, unless someone remembered to manually submit the same thing to the other branch and actually made the effort to do so.
Most of the time, this wouldn't happen.
When it did, it would mean a second pull request that would have to be reviewed.
Over time, the different branches would diverge in non-version-specific content.
Good general content that was submitted only to one branch would effectively disappear once that version was deprecated.
(Even if it were still on the website, no one would look at it, since it would explicitly be in the subdirectory of a deprecated version, and there would be a motivation to remove it from the website so that search results wouldn't be populated with out-of-date information.)

All the documentation is written in Markdown for maximum accessibility. When
making contributions, please try to observe the following style conventions:
* Use spaces instead of tabs.
* Do not write HTML inside Markdown documents (except in rare, unavoidable cases, such as alerts).
In particular, never include HTML or CSS for styling, formatting, or white space control.
That belongs in the (S)CSS files instead.
* Link only to images in [qubes-attachment](https://github.com/QubesOS/qubes-attachment) (see [instructions above](#how-to-add-images)).
Do not link to images on other websites.
* In order to enable offline browsing and automatic onion redirection, always use relative (rather than absolute) links, e.g., `/doc/doc-guidelines/` instead of `https://www.qubes-os.org/doc/doc-guidelines/`.
Examples of exceptions:
* The signed plain text portions of [QSBs](/security/bulletins/) and [Canaries](/security/canaries/)
