投稿指南

Contributions to the PX4 User Guide are very welcome; from simple fixes to spelling and grammar, through to the creation of whole new sections.

This topic explains how to make and test changes. Towards the end there is a basic style guide.

TIP

Note You will need a (free) Github account to contribute to the guides.

快速更改

Simple changes to existing content can be made by clicking the Edit on GitHub link that appears at the bottom of every page (this opens the page on Github for editing).

The guide uses the Gitbook toolchain. Change requests can be either done on the Gitbook website using the Gitbook editor or locally (more flexible, but less user-friendly).

1. Open the page.
2. Click the Edit on GitHub link below the page content.
3. At the bottom of the page you'll be prompted to create a separate branch and then guided to submit a pull request.
4. Below the Github page editor you'll be prompted to create a separate branch and then guided to submit a pull request.

The documentation team will review the request and either merge it or work with you to update it.

Adding New Content - Big Changes

More substantial changes, including adding new pages or adding/modifying images, aren't as easy to make (or properly test) on Github. For these kinds of changes we suggest using the same approach as for code:

1. Use the git toolchain to get the documentation source code onto your local computer.
2. Modify the documentation as needed (add, change, delete).
3. Test that it builds properly using Vitepress.
4. In order to contribute many changes to the documentation, it is recommended that you follow these steps to add the changes locally and then create a pull request:

The following explain how to get the source code, build locally (to test), and modify the code.

What Goes Where?

指南使用 旧版Gitbook 工具链 The instructions below explain how to get git and use it on your local computer.

1. git add <file name> git commit -m "<your commit message>"

2. 如果您还没有注册Github，请先注册 Github 账户

3. Create a copy (Fork) of the PX4 User Guide repo on Github (instructions here).

4. Clone (copy) your forked repository to your local computer:

   cd ~/wherever/
   git clone https://github.com/<your git name>/PX4-user_guide.git

   For example, to clone the PX4 userguide fork for a user with Github account "john_citizen":

   git clone https://github.com/john_citizen/PX4-user_guide.git

5. Navigate to your local repository:

   cd ~/wherever/PX4-user_guide

6. Add a remote called "upstream" to point to the PX4 version of the library:

   git remote add upstream https://github.com/PX4/PX4-user_guide.git

TIP

A "remote" is a handle to a particular repository. The remote named origin is created by default when you clone the repository, and points to your fork of the guide. Above you create a new remote upstream that points to the PX4 project version of the documents.

1. Create a branch for your changes:

   git checkout -b <your_feature_branch_name>

   This creates a local branch on your computer named your_feature_branch_name.

2. Make changes to the documentation as needed (general guidance on this in following sections)

3. Once you are satisfied with your changes, you can add them to your local branch using a "commit":

   git add <file name>
   git commit -m "<your commit message>"

   For a good commit message, please refer to the Source Code Management section.

4. Push your local branch (including commits added to it) to your forked repository on Github.

   git push origin your_feature_branch_name

5. Go to your forked repository on Github in a web browser, e.g.: https://github.com/<your git name>/PX4-user_guide.git. There you should see the message that a new branch has been pushed to your forked repository.

6. Create a pull request (PR):

   • On the right hand side of the "new branch message" (see one step before), you should see a green button saying "Compare & Create Pull Request". Press it.
   • A pull request template will be created. It will list your commits and you can (must) add a meaningful title (in case of a one commit PR, it's usually the commit message) and message (explain what you did for what reason. Check other pull requests for comparison)

7. You're done! Maintainers for the PX4 User Guide will now have a look at your contribution and decide if they want to integrate it. Check if they have questions on your changes every once in a while.

Gitbook Documentation Toolchain

概述：

1. Install the Vitepress prerequisites:

   • Nodejs 18+
   • Yarn classic

2. Navigate to your local repository:

   cd ~/wherever/PX4-user_guide

3. Install dependencies (including Vitepress):

   yarn install

4. Preview and serve the library:

   yarn start

   • Once the development/preview server has built the library (less than a minute for the first time) it will show you the URL you can preview the site on. This will be something like: http://localhost:5173/px4_user_guide/.
   • Stop serving using CTRL+C in the terminal prompt.

5. You can build the library as it would be done for deployment:

   # Ubuntu
   yarn docs:build
   
   # Windows
   yarn docs:buildwin

TIP

Use yarn start to preview changes as you make them (documents are updated and served very quickly). Before submitting a PR you should also build it using yarn docs:build, as this can highlight issues that are not visible when using yarn start.

Source Code Structure

The guide uses the Vitepress toolchain.

In overview:

• Pages are written in separate files using markdown.

  • The syntax is almost the same as that used by the Github wiki.
  • Vitepress also supports some markdown extensions. We try and avoid using these, except for tips, warning, etc.. This might be revisited - there are some interesting options provided!

• This is a multilingual book:

  • Pages for each language are stored in the folder named for the associated language code (e.g. "en" for English, "zh" for Chinese, "ko" for Korean).
  • Only edit the ENGLISH (/en) version of files. We use Crowdin to manage the translations.

• All pages must be in an appropriately named sub-folder of /en (e.g. this page is in folder en/contribute/).

  • This makes linking easier because other pages and images are always as the same relative levels

• The structure of the book is defined in SUMMARY.md

  • If you add a new page to the guide you must also add an entry to this file!

TIP

This is not "standard vitepress" way to define the sidebar (the summary file is imported by .vitepress/get_sidebar.js).

• Images must be stored in a sub folder of /assets. This is two folders down from content folders, so if you add an image you will reference it like:

  ![Image Description](../../assets/path_to_file/filename.jpg)

• A file named package.json defines any dependencies of the build.

• A web hook is used to track whenever files are merged into the master branch on this repository, causing the book to rebuild.

翻译

1. 图片

   • Put new files in an appropriate sub-folder of /en/. Do not further nest folders.
   • The structure of the book is defined in a file named SUMMARY.md. In particular, image filenames should describe what they contain.
   • This is a multilingual book, so there is a LANGS.md file in the root directory defining what languages are supported. Pages for each language are stored in the folder named for the associated language code (e.g. "zh" for Chinese, "en" for English).

2. 内容:

   • 将新文件放入相应的子文件夹
   • New images should be created in a sub-folder of /assets/ by default (so they can be shared between translations).

3. Content:

   • Use "style" (bold, emphasis, etc) consistently.
     • Bold for button presses and menu definitions.
     • Emphasis for tool names. - Otherwise use as little as possible.
   • New images should be created in a sub-folder of /assets/ by default (so they can be shared between translations).
   • The page title should be a first level heading (#). All other headings should be h2 (##) or lower.
   • Don't add any style to headings.
   • Don't translate the first part of a note, tip or warning declaration (e.g. ::: tip) as this precise text is required to render the note properly.

许可证

Add new documentation in-line with the existing structure!

Some of the main categories are:

• Development: content related to:
  • Evolving the platform (new modes, modules, flight modes, hardware, software and hardware architecture and porting).
  • "Experimental" work that requires developer expertise to reproduce.
• Flying: content related to flying a standard vehicle (flight modes, arming, taking off, landing)
• Basic configuration: Configuration that every vehicle will need to do
• Advanced configuration: Configuration that is specific to a vehicle type, or some segment of users.
• Peripherals: Documentation on different hardware that can be used.
  • This also includes setup and configuration information for hardware that isn't covered in Basic configuration.
• Basic Assembly: Assembly of an autopilot and its main peripherals
• Airframe Builds: Examples of how to build a whole system.
