All Qubes OS documentation pages are stored as plain text files in the dedicated 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.
The documentation is a community effort. Volunteers work hard trying to keep everything accurate and comprehensive. If you notice a problem with the documentation or some way it can be improved, please report it! Better yet, you can edit the documentation yourself, both to add or improve existing content.
Questions, problems, and improvements
If you have a question about something you read in the documentation, please send it to the appropriate mailing list. If you see that something in the documentation should be fixed or improved, please contribute the change yourself. To report an issue with the documentation, please follow our standard issue reporting guidelines. (If you report an issue with the documentation, you will likely be asked to address it, unless there is a clear indication in your report that you are not willing or able to do so.)
How to Contribute
Editing the documentation is easy, so if you spot any errors, please help us fix them! (As mentioned above, the documentation maintainers are just volunteers who have day jobs of their own, so we rely heavily on the community to improve the documentation.) Since Qubes is a security-oriented project, every documentation change will be reviewed before it’s published to the web. This allows us to maintain quality control and protect our users.
As mentioned above, we keep all the documentation in a dedicated Git repository hosted on GitHub. Thanks to the GitHub’s interface, you can edit the documentation even if you don’t know Git at all! The only thing you need is a GitHub account, which is free.
(Note: If you’re already familiar with GitHub or wish to work from the command line, you can skip the rest of this section. All you need to do to contribute is to fork and clone the qubes-doc repo, make your changes, then submit a pull request.)
Ok, let’s start. Every documentation page has an “Edit this page” button. It may be on the right side (in the desktop layout):
Or at the bottom (in the mobile layout):
When you click on it, you’ll be prompted for your GitHub username and password (if you aren’t already logged in). You can also create an account from here.
If this is your first contribution to the documentation, you need to “fork” the repository (make your own copy). It’s easy — just click the big green button on the next page. This step is only needed the first time you make a contribution.
Now you can make your modifications. You can also preview the changes to see how they’ll be formatted by clicking the “Preview changes” tab.
Once you’re finished, describe your changes at the bottom and click “Propose file change”.
After that, you’ll see exactly what modifications you’ve made. At this stage, those changes are still in your own copy of the documentation (“fork”). If everything looks good, send those changes to us by pressing the “Create pull request” button.
You will be able to adjust the pull request message and title there. In most cases, the defaults are ok, so you can just confirm by pressing the “Create pull request” button again.
That’s all! We will review your changes. If everything looks good, we’ll pull them into the official documentation. Otherwise, we may have some questions for you, which we’ll post in a comment on your pull request. (GitHub will automatically notify you if we do.) If, for some reason, we can’t accept your pull request, we’ll post a comment explaining why we can’t.
How to add images
To add an image to a page, use the following syntax in the main document:
Then, submit your image(s) in a separate pull request to the qubes-attachment repository using the same path and filename.
We maintain only one set of documentation for Qubes OS. We do not maintain a different set of documentation for each version of Qubes. Our single set of Qubes OS documentation is updated on a continual, rolling basis. Our first priority is to document all current, stable releases of Qubes. Our second priority is to document the next, upcoming release (if any) that is currently in the beta or release candidate stage.
In cases where a documentation page covers functionality that differs considerably between Qubes OS versions, the page should be subdivided into clearly-labeled sections that cover the different functionality in different versions:
# Page Title # ## How to Foo ## Fooing is the process by which one foos. There are both general and specific versions of fooing, which vary in usefulness depending on your goals, but for the most part, all fooing is fooing. To foo in Qubes 3.2: $ qvm-foo <foo-bar> Note that this does not work in Qubes 4.0, where there is a special widget for fooing, which you can find in the lower-right corner of the screen in the Foo Manager. Alternatively, you can use the more general `qubes-baz` command introduced in 4.0: $ qubes-baz --foo <bar> Once you foo, make sure to close the baz before fooing the next bar.
# Page Title # ## Qubes 3.2 ## ### How to Foo ### Fooing is the process by which one foos. There are both general and specific versions of fooing, which vary in usefulness depending on your goals, but for the most part, all fooing is fooing. To foo: $ qvm-foo <foo-bar> Once you foo, make sure to close the baz before fooing the next bar. ## Qubes 4.0 ## ### How to Foo ### Fooing is the process by which one foos.

Here is a good example of a page that is correctly subdivided to account for version-specific differences. 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.
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.)

If you find any inaccuracies in the documentation, please correct them!
If you find an inaccuracy but don’t know how to correct it, you can still help by documenting the inaccuracy. For example, if you have thoroughly tested a set of steps in the documentation and know for certain that they no longer work on a certain version of Qubes (maybe because the steps are out-of-date), then please add a note to the documentation indicating this. You may also wish to provide a link to a relevant thread on the [mailing lists].
Where appropriate, specify the version of the software to which your contribution applies. For example, if you’re contributing a set of instructions for doing something in dom0, specify the version(s) of Qubes OS with which you know these instructions to work. This allows future readers to more easily estimate the accuracy and applicability of information.
- Familiarize yourself with the terms defined in the glossary. Use these terms consistently and accurately throughout your writing.
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.
- In order to enable offline browsing, use relative paths (e.g.,
https://www.qubes-os.org/doc/doc-guidelines/, except when the source text will be reproduced outside of the Qubes website repo. Examples of exceptions:
- Insert a newline at, and only at, the end of each sentence, except when the text will be reproduced outside of the Qubes website repo (see previous item for examples).
- Rationale: This practice results in one sentence per line, which is most appropriate for source that consists primarily of natural language text. It results in the most useful diffs and facilitates translation into other languages while mostly preserving source readability.
- If appropriate, make numerals in numbered lists match between Markdown source and HTML output.
- Rationale: In the event that a user is required to read the Markdown source directly, this will make it easier to follow, e.g., numbered steps in a set of instructions.
- Use hanging indentations
- Use underline headings (
-----) if possible. If this is not possible, use Atx-style headings on both the left and right sides (
### H3 ###).
(This is a great source for learning about Markdown.)
