Clone your fork to your local machine: ```bash git clone https://github.com/YOUR-GITHUB-USERNAME/netdata.git ``` -You can now jump into the directory and explore Netdata's structure for yourself. - -### Understanding the structure of Netdata's documentation - -All of Netdata's documentation is stored within the repository itself, as close as possible to the code it -corresponds to. Many sub-folders contain a `README.md` file, -which is then used to populate the documentation about that feature/component of Netdata. - -For example, the file at `packaging/installer/README.md` becomes `https://docs.netdata.cloud/packaging/installer/` -and is our installation documentation. By co-locating it with quick-start installtion code, -we ensure documentation is always tightly knit with the functions it describes. - -You might find other `.md` files within these directories. The `packaging/installer/` folder also contains `UPDATE.md` -and `UNINSTALL.md`, which become `https://docs.netdata.cloud/packaging/installer/update/` -and `https://docs.netdata.cloud/packaging/installer/uninstall/`, respectively. - -If the documentation you're working on has a direct correlation to some component of Netdata, place it into the correct -folder and either name it `README.md` for generic documentation, or with another name for very specific instructions. - -#### The `docs` folder - -At the root of the Netdata repository is a `docs/` folder. Inside this folder we place documentation that does not have -a direct relationship to a specific component of Netdata. It's where we house our [getting started -guide](../../docs/getting-started.md), guides on [running Netdata behind Nginx](../../docs/Running-behind-nginx.md), and -more. - -If the documentation you're working on doesn't have a direct relaionship to a component of Netdata, -it can be placed in this `docs/` folder. - -### Make your edits - -Now that you're set up and understand where to find or create your `.md` file, you can now begin to make your edits. -Just use your favorite editor and keep in mind our [style guide](style-guide.md) as you work. - -If you add a new file to the documentation, you may need to modify the `buildyaml.sh` file to ensure -it's added to the site's navigation. This is true for any file added to the `docs/` folder. - -Be sure to periodically add/commit your edits so that you don't lose your work! -We use version control software for a reason. - -### Build the documentation - -Building the documentation periodically gives you a glimpse into the final product, and is generally required -if you're making changes to the table of contents. - -!!! attention "" - We have only tested the build process on Linux. Initial tests on OS X have been unsuccessful. - Windows is fully untested at this point, but we would love to know if it works there as well! - -To build the documentation, you need `python`/`pip`, `mkdocs`, and `mkdocs-material` installed on your machine. - -Follow the [Python installation instructions](https://www.python.org/downloads/) for your machine. - -Use `pip`, which was installed alongside Python, to install `mkdocs` and `mkdocs-material`. -Your operating system might force you to use `pip2` or `pip3` instead, -dependin on which version of Python you have installed. - -```bash -pip install mkdocs mkdocs-material -``` - -??? note "Troubleshooting" - If you're having trouble with the installation of Python, `mkdocs`, or `mkdocs-material`, try looking into the `mkdocs` [installation instructions](https://squidfunk.github.io/mkdocs-material/getting-started/#installation). - -When `pip` is finished installing, navigate to the root directory of the Netdata repository -and run the documentation generator script. - -```bash -sh docs/generator/buildhtml.sh -``` - -This process will take some time. Once finished, the built documentation site will be located at `docs/generator/build/`. - -### Run a local web server to test documentation - -The best way to view the documentation site you just built is to run a simple web server from the `docs/generator/build/` directory. -So, navigate there and run a Python-based web server: - -```sh -cd docs/generator/build/ -python3 -m http.server 20000 -``` - -Feel free to replace the port number you want this web server to listen on (port `20000` in this case (only one higher -than the agent!)). - -Open your web browser and navigate to `http://localhost:20000`. -If you replaced the port earlier, change it here as well. -You can now navigate through the documentation as you would on the live site! +Create a new branch using `git checkout -b BRANCH-NAME`. Use your favorite text editor to make your changes, keeping the +[Netdata style guide](/docs/contributing/style-guide.md) in mind. Add, commit, and push changes to your fork.

The health of our monitoring agent, and the community it's created, depends on this effort. +## Voice and tone -We’re here to make developers, sysadmins, and DevOps engineers better at their jobs, after all! +One way we write empowering, educational content is by using a consistent voice and an appropriate tone. -We welcome contributions to Netdata's documentation. Begin with the [contributing to documentation guide](contributing-documentation.md), followed by this style guide. +_Voice_ is like your personality, which doesn't really change day to day. -## Goals of the Netdata style guide +_Tone_ is how you express your personality. Your expression changes based on your attitude or mood, or based on who +you're around.

At Netdata, we focus on the following principles: +The same idea about voice and tone applies to organizations, too. Our voice shouldn't change much between two pieces of +content, no matter who wrote each, but the tone might be quite different based on who we think is reading. -- Consistency -- High-quality writing -- Conciseness -- Accessibility +For example, a [blog post](https://www.netdata.cloud/blog/) and a [press release](https://www.netdata.cloud/news/) +should have a similar voice, despite most often being written by different people. However, blog posts are relaxed and +witty, while press releases are focused and academic. You won't see any emoji in a press release. -These principles will make documentation better for everyone who wants to use Netdata, whether they're a beginner or an expert. +### Voice -### Breaking the rules +Netdata's voice is authentic, passionate, playful, and respectful. -None of the rules described in this style guide are absolute. **We welcome rule-breaking if it creates better, more accessible documentation.** +- **Authentic** writing is honest and fact-driven. Focus on Netdata's strength while accurately communicating what + Netdata can and cannot do, and emphasize technical accuracy over hard sells and marketing jargon. +- **Passionate** writing is strong and direct.

Don't take yourself too seriously, as long as it's not at + the expense of Netdata or any of its users. +- **Respectful** writing treats people the way you want to be treated. Prioritize giving solutions and answers as + quickly as possible. -But be aware that Netdata staff or community members may ask you to justify your rule-breaking during the PR review process. +### Tone -## General principles +Netdata's tone is fun and playful, but clarity and conciseness comes first. We also tend to be informal, and aren't +afraid of a playful joke or two. -Yes, this style guide is pretty overwhelming! Establishing standards for a global community is never easy. +While we have general standards for voice and tone, we do want every individual's unique writing style to reflect in +published content. -Here's a few key points to start with. Where relevant, they link to more in-depth information about a given rule. +## Universal communication -**[Tone and content](#tone-and-content)**: +Netdata is a global company in every sense, with employees, contributors, and users from around the world. We strive to +communicate in a way that is clear and easily understood by everyone. -- Be [conversational and friendly](#conversational-and-friendly-tone). -- Write [concisely](#write-concisely). -- Don't use words like **here** when [creating hyperlinks](#use-informational-hyperlinks). -- Don't mention [future releases or features](#mentioning-future-releases-or-features) in documentation. +Here are some guidelines, pointers, and questions to be aware of as you write to ensure your writing is universal. Some +of these are expanded into individual sections in the [language, grammar, and +mechanics](#language-grammar-and-mechanics) section below. -**[Language and grammar](#language-and-grammar)**: +- Would this language make sense to someone who doesn't work here? +- Could someone quickly scan this document and understand the material? +- Create an information hierarchy with key information presented first and clearly called out to improve scannability. +- Avoid directional language like "sidebar on the right of the page" or "header at the top of the page" since + presentation elements may adapt for devices. +- Use descriptive links rather than "click here" or "learn more". +- Include alt text for images and image links. +- Ensure any information contained within a graphic element is also available as plain text. +- Avoid idioms that may not be familiar to the user or that may not make sense when translated. +- Avoid local, cultural, or historical references that may be unfamiliar to users. +- Prioritize active, direct language. +- Avoid referring to someone's age unless it is directly relevant; likewise, avoid referring to people with age-related + descriptors like "young" or "elderly." +- Avoid disability-related idioms like "lame" or "falling on deaf ears." Don't refer to a person's disability unless + it’s directly relevant to what you're writing. +- Don't call groups of people "guys." Don't call women "girls." +- Avoid gendered terms in favor of neutral alternatives, like "server" instead of "waitress" and "businessperson" + instead of "businessman." +- When writing about a person, use their communicated pronouns. When in doubt, just ask or use their name. It's OK to + use "they" as a singular pronoun. -- [Capitalize words](#capitalization) at the beginning of sentences, for proper nouns, and at the beginning of document titles and section headers. -- Use [second person](#second-person)—"you" rather than "we"—when giving instructions. -- Use [active voice](#active-voice) to make clear who or what is performing an action. -- Always employ an [Oxford comma](#oxford-comma) on lists. +> Some of these guidelines were adapted from MailChimp under the Creative Commons license. -**[Markdown syntax](#markdown-syntax)**: +## Language, grammar, and mechanics -- [Reference UI elements](#references-to-ui-elements) with bold text. -- Use our [built-in syntax highlighter](#language-specific-syntax-highlighting-in-code-blocks) to improve the readability and usefulness of code blocks. +To ensure Netdata's writing is clear, concise, and universal, we have established standards for language, grammar, and +certain writing mechanics. However, if you're writing about Netdata for an external publication, such as a guest blog +post, follow that publication's style guide or standards, while keeping the [preferred spelling of Netdata +terms](#netdata-specific-terms) in mind. -**[Accessibility](#accessibility)**: +### Active voice -- Include [alt tags on images](#images). +Active voice is more concise and easier to understand compared to passive voice. When using active voice, the subject of +the sentence is action. In passive voice, the subject is acted upon. A famous example of passive voice is the phrase +"mistakes were made." ---- +| | | +|-----------------|---------------------------------------------------------------------------------------------| +| Not recommended | When an alarm is triggered by a metric, a notification is sent by Netdata. | +| **Recommended** | When a metric triggers an alarm, Netdata sends a notification to your preferred endpoint. | -## Tone and content +### Second person -Netdata's documentation should be conversational, concise, and informational, without feeling formal. This isn't a textbook. It's a repository of information that should (on occasion!) encourage and excite its readers. +Use the second person ("you") to give instructions or "talk" directly to users. -By following a few principles on tone and content we'll ensure more readers from every background and skill level will learn as much as possible about Netdata's capabilities. +In these situations, avoid "we," "I," "let's," and "us," particularly in documentation. The "you" pronoun can also be +implied, depending on your sentence structure. -### Conversational and friendly tone +One valid exception is when a member of the Netdata team or community wants to write about said team or community. -Netdata's documentation should be conversational and friendly.

Documentation can be highly professional without being dry, formal, or overly instructive. +Using words that imply the complexity of a task or feature goes against our policy of [universal +communication](#universal-communication). If you claim that a task is easy and the reader struggles to complete it, you +may inadvertently discourage them. -### Write concisely +However, if you give users two options and want to relay that one option is genuinely less complex than another, be +specific about how and why. -You should always try to use as few words as possible to explain a particular feature, configuration, or process. Conciseness leads to more accurate and understandable writing. +For example, don't write, "Netdata's one-line installer is the easiest way to install Netdata." Instead, you might want +to say, "Netdata's one-line installer requires fewer steps than manually installing from source." -### Use informational hyperlinks +### Slang, metaphors, and jargon -Hyperlinks should clearly state its destination. Don't use words like "here" to describe where a link will take your reader. +A particular word, phrase, or metaphor you're familiar with might not translate well to the other cultures featured +among Netdata's global community. We recommended you avoid slang or colloquialisms in your writing. -``` -# Not recommended -To install Netdata, click [here](https://docs.netdata.cloud/packaging/installer/). +In addition, don't use abbreviations that have not yet been defined in the content.

(Netdata, Docker, Apache, Nginx) -- Avoid camel case (NetData) or all caps (NETDATA). +When introducing an abbreviation to a document for the first time, give the reader both the spelled-out version and the +shortened version at the same time. For example: -#### Capitalization of 'Netdata' and 'netdata' +> Use Netdata to monitor Extended Berkeley Packet Filter (eBPF) metrics in real-time. -Whenever you refer to the company Netdata, Inc., or the open-source monitoring agent the company develops, capitalize **Netdata**. +After you define an abbreviation, don't switch back and forth. Use only the abbreviation for the rest of the document. -However, if you are referring to a process, user, or group on a Linux system, you should not capitalize, as by default those are typically lowercased. In this case, you should also fence these terms in an inline code block: `` `netdata` ``. +You can also use abbreviations in a document's title to keep the title short and relevant. If you do this, you should +still introduce the spelled-out name alongside the abbreviation as soon as possible. -``` -# Not recommended -The netdata agent, which spawns the netdata process, is actively maintained by netdata, inc. +### Clause order -# Recommended -The Netdata agent, which spawns the `netdata` process, is actively maintained by Netdata, Inc. -``` +When instructing users to take action, give them the context first.

When using the second person, you give the impression that you're personally leading your reader through the steps or tips in question. +### Informational links -See how that works? It's a core part of making Netdata's documentation feel welcoming to all. +Every link should clearly state its destination. Don't use words like "here" to describe where a link will take your +reader. -Avoid using "we," "I," "let's," and "us" in documentation whenever possible. +| | | +|-----------------|-------------------------------------------------------------------------------------------| +| Not recommended | To install Netdata, click [here](/packaging/installer/README.md). | +| **Recommended** | To install Netdata, read the [installation instructions](/packaging/installer/README.md). | -The "you" pronoun can also be implied, depending on your sentence structure. +Use links as often as required to provide necessary context.

Those who *do* want to read it are less likely to skip over the sentence. +When instructing users to run a Netdata-specific command, don't assume the path to said command, because not every +Netdata Agent installation will have commands under the same paths.

If you're not familiar with how it works, please read the [Markdown introduction post](https://daringfireball.net/projects/markdown/) by its creator, followed by [Mastering Markdown](https://guides.github.com/features/mastering-markdown/) guide from GitHub. +Netdata's documentation uses Markdown syntax. -We also leverage the power of the [Material theme for MkDocs](https://squidfunk.github.io/mkdocs-material/), which features several [extensions](https://squidfunk.github.io/mkdocs-material/extensions/admonition/), such as the ability to create notes, warnings, and collapsible blocks. +If you're not familiar with Markdown, read the [Mastering +Markdown](https://guides.github.com/features/mastering-markdown/) guide from GitHub for the basics on creating +paragraphs, styled text, lists, tables, and more. -You can follow the syntax specified in the above resources for the majority of documents, but the following sections specify a few particular use cases. +The following sections describe situations in which a specific syntax is required. -### References to UI elements +### Syntax standards (`remark-lint`) + +The Netdata team uses [`remark-lint`](https://github.com/remarkjs/remark-lint) for Markdown code styling. + +- Use a maximum of 120 characters per line. +- Begin headings with hashes, such as `# H1 heading`, `## H2 heading`, and so on. +- Use `_` for italics/emphasis. +- Use `**` for bold. +- Use dashes `-` to begin an unordered list, and put a single space after the dash. +- Tables should be padded so that pipes line up vertically with added whitespace. + +If you want to see all the settings, open the +[`remarkrc.js`](https://github.com/netdata/netdata/blob/master/.remarkrc.js) file in the `netdata/netdata` repository. + +### Frontmatter + +Every document must begin with frontmatter, followed by an H1 (`#`) heading. + +Unlike typical Markdown frontmatter, Netdata uses HTML comments (`<!--`, `-->`) to begin and end the frontmatter block. +These HTML comments are later converted into typical frontmatter syntax when building [Netdata +Learn](https://learn.netdata.cloud). + +Frontmatter _must_ contain the following variables: + +- A `title` that quickly and distinctly describes the document's content. +- A `description` that elaborates on the purpose or goal of the document using no less than 100 characters and no more + than 155 characters. +- A `custom_edit_url` that links directly to the GitHub URL where another user could suggest additional changes to the + published document. + +Some documents, like the Ansible guide and others in the `/docs/guides` folder, require an `image` variable as well. In +this case, replace `/docs` with `/img/seo`, and then rebuild the remainder of the path to the document in question. End +the path with `.png`. A member of the Netdata team will assist in creating the image when publishing the content. -If you need to instruct your reader to click a user interface (UI) element inside of a Netdata interface, you should reference the label text of the link/button with Markdown's (`**bold text**`) tag. +For example, here is the frontmatter for the guide about [deploying the Netdata Agent with +Ansible](https://learn.netdata.cloud/guides/deploy/ansible). ```markdown -Click on the **Sign in** button. +<!-- +title: Deploy Netdata with Ansible +description: "Deploy an infrastructure monitoring solution in minutes with the Netdata Agent and Ansible.

[Ask on our community +forum](https://community.netdata.cloud/c/blog-posts-and-articles/6). + +### Linking between documentation + +Documentation should link to relevant pages whenever it's relevant and provides valuable context to the reader. + +Links should always reference the full path to the document, beginning at the root of the Netdata Agent repository +(`/`), and ending with the `.md` file extension. Avoid relative links or traversing up directories using `../`. +For example, if you want to link to our node configuration document, link to `/docs/configure/nodes.md`. To reference +the guide for deploying the Netdata Agent with Ansible, link to `/docs/guides/deploy/ansible.md`. + +### References to UI elements + +When referencing a user interface (UI) element in Netdata, reference the label text of the link/button with Markdown's +(`**bold text**`) tag. + +```markdown +Click the **Sign in** button. ``` -If you feel that you must use directional language, perhaps use an [image](#images) (with proper alt text) instead. -We're also working to establish standards for how we refer to certain elements of the Netdata's web interface. We'll include that in this style guide as soon as it's complete. +Avoid directional language whenever possible. Not every user can use instructions like "look at the top-left corner" to +find their way around an interface, and interfaces often change between devices. If you must use directional language, +try to supplement the text with an [image](#images). + +### Images + +Don't rely on images to convey features, ideas, or instructions. Accompany every image with descriptive alt text. + +In Markdown, use the standard image syntax, `![]()`, and place the alt text between the brackets `[]`. Here's an example +using our logo: + +```markdown + ``` -### Language-specific syntax highlighting in code blocks +Reference in-product text, code samples, and terminal output with actual text content, not screen captures or other +images. Place the text in an appropriate element, such as a blockquote or code block, so all users can parse the +information. -Our documentation uses the [Highlight extension](https://facelessuser.github.io/pymdown-extensions/extensions/highlight/) for syntax highlighting. Highlight is fully compatible with [Pygments](http://pygments.org/), allowing you to highlight the syntax within code blocks in a number of interesting ways. +### Syntax highlighting -For a full list of languages, see [Pygment's supported languages](http://pygments.org/languages/). Netdata documentation will use the following for the most part: `c`, `python`, `js`, `shell`, `markdown`, `bash`, `css`, `html`, and `go`.

Highlight lines by appending `hl_lines="2"`, replacing `2` with the line you'd like to highlight. Or, multiple lines: `hl_lines="1 2 4 12`. +## Word list -!!! note - Line numbers and highlights are not compatible with GitHub's Markdown parser, and thus will only be viewable on our [documentation site](https://docs.netdata.cloud/). They should be used sparingly and only when necessary. +The following tables describe the standard spelling, capitalization, and usage of words found in Netdata's writing. -## Accessibility +### Netdata-specific terms -Netdata's documentation should be as accessible as possible to as many people as possible. While the rules about [tone and content](#tone-and-content) and [language and grammar](#language-and-grammar) are helpful to an extent, we also need some additional rules to improve the reading experience for all readers. - -### Images - -Images are an important component to documentation, which is why we have a few rules around their usage. - -Perhaps most importantly, don't use only images to convey instructions. Each image should be accompanied by alt text and text-based instructions to ensure that every reader can access the information in the best way for them. - -#### Alt text - -Provide alt text for every image you include in Netdata's documentation. It should summarize the intent and content of the image. - -In Markdown, use the standard image syntax, `![]()`, and place the alt text between the brackets `[]`.
