- Do you work on one of the various OpenSearch plugins? Take a look at the documentation for the plugin. Is everything accurate? Will anything change in the near future?
- 你是否对 OpenSearch 的特定领域有专业的知识吗？集群大小？查询语言（DSL）？Do you have expertise in a particular area of OpenSearch? Cluster sizing? 无痛脚本（Painless scripting）？聚合（Aggregations）？JVM 设置？请查看 [OpenSearch 当前内容](https://opensearch.ossez.com/) 来了解你是否可以为项目加入一些有价值的内容。 [OpenSearch 文档项目组](#points-of-contact) 非常高兴能够帮助你对内容进行润色和重新组织你的草稿。
This repository contains many [Markdown](https://guides.github.com/features/mastering-markdown/) files organized into Jekyll "collections" (e.g. `_search-plugins`, `_opensearch`, etc.). Each Markdown file correlates with one page on the website.
- Everything is free, open source, and works on every operating system. Use your favorite text editor, Ruby, Jekyll, and Git.
- Markdown is easy to learn and looks good in side-by-side diffs.
- The workflow is no different than contributing code. Make your changes, build locally to check your work, and submit a pull request. Reviewers check the PR before merging.
- Alternatives like wikis and WordPress are full web applications that require databases and ongoing maintenance. They also have inferior versioning and content review processes compared to Git. Static websites, such as the ones Jekyll produces, are faster, more secure, and more stable.
In addition to the content for a given page, each Markdown file contains some Jekyll [front matter](https://jekyllrb.com/docs/front-matter/). Front matter looks like this:
```
---
layout: default
title: Alerting security
nav_order: 10
parent: Alerting
has_children: false
---
```
If you're making [trivial changes](#trivial-changes), you don't have to worry about front matter.
If you want to reorganize content or add new pages, keep an eye on `has_children`, `parent`, and `nav_order`, which define the hierarchy and order of pages in the lefthand navigation. For more information, see the documentation for [our upstream Jekyll theme](https://pmarsceill.github.io/just-the-docs/docs/navigation-structure/).
## Contribute content
There are three ways to contribute content, depending on the magnitude of the change.
- [Trivial changes](#trivial-changes)
- [Minor changes](#minor-changes)
- [Major changes](#major-changes)
### Trivial changes
If you just need to fix a typo or add a sentence, this web-based method works well:
1. On any page in the documentation, click the **Edit this page** link in the lower-left.
1. Make your changes.
1. Choose **Create a new branch for this commit and start a pull request** and **Commit changes**.
### Minor changes
If you want to add a few paragraphs across multiple files and are comfortable with Git, try this approach:
1. Fork this repository.
1. Download [GitHub Desktop](https://desktop.github.com), install it, and clone your fork.
1. Navigate to the repository root.
1. Create a new branch.
1. Edit the Markdown files in `/docs`.
1. Commit, push your changes to your fork, and submit a pull request.
### Major changes
If you're making major changes to the documentation and need to see the rendered HTML before submitting a pull request, here's how to build locally:
1. Fork this repository.
1. Download [GitHub Desktop](https://desktop.github.com), install it, and clone your fork.
1. Navigate to the repository root.
1. Install [Ruby](https://www.ruby-lang.org/en/) if you don't already have it. We recommend [RVM](https://rvm.io/), but use whatever method you prefer:
```
curl -sSL https://get.rvm.io | bash -s stable
rvm install 2.6
ruby -v
```
1. Install [Jekyll](https://jekyllrb.com/) if you don't already have it:
1. When you save a file, marvel as Jekyll automatically rebuilds the site and refreshes your web browser. This process can take anywhere from 10-30 seconds.
1. When you're happy with how everything looks, commit, push your changes to your fork, and submit a pull request.
## Writing tips
1. Try to stay consistent with existing content and consistent within your new content. Don't call the same plugin KNN, k-nn, and k-NN in three different places.
1. Shorter paragraphs are better than longer paragraphs. Use headers, tables, lists, and images to make your content easier for readers to scan.
1. Use **bold** for user interface elements, *italics* for key terms or emphasis, and `monospace` for Bash commands, file names, REST paths, and code.
1. Markdown file names should be all lowercase, use hyphens to separate words, and end in `.md`.
1. Avoid future tense. Use present tense.
**Bad**: After you click the button, the process will start.
**Better**: After you click the button, the process starts.
1. "You" refers to the person reading the page. "We" refers to the OpenSearch contributors.
**Bad**: Now that we've finished the configuration, we have a working cluster.
**Better**: At this point, you have a working cluster, but we recommend adding dedicated master nodes.
1. Don't use "this" and "that" to refer to something without adding a noun.
**Bad**: This can cause high latencies.
**Better**: This additional loading time can cause high latencies.
1. Use active voice.
**Bad**: After the request is sent, the data is added to the index.
**Better**: After you send the request, the OpenSearch cluster indexes the data.
1. Introduce acronyms before using them.
**Bad**: Reducing customer TTV should accelerate our ROIC.
**Better**: Reducing customer time to value (TTV) should accelerate our return on invested capital (ROIC).
1. Spell out one through nine. Start using numerals at 10. If a number needs a unit (GB, pounds, millimeters, kg, celsius, etc.), use numerals, even if the number if smaller than 10.
**Bad**: 3 kids looked for thirteen files on a six GB hard drive.
**Better**: Three kids looked for 13 files on a 6 GB hard drive.
Use `docker ps` to find the ID for the OpenSearch Dashboards node. Then use `docker exec -it <opensearch-dashboards-node-id> /bin/bash` to get shell access. Finally, run `./bin/opensearch-dashboards-plugin list` to get the plugins and version strings.
1. Run a build (`build.sh`), and look for any warnings or errors you introduced.
1. Verify that the individual plugin download links in `docs/install/plugins.md` and `docs/opensearch-dashboards/plugins.md` work.
1. Check for any other bad links (`check-links.sh`). Expect a few false positives for the `localhost` links.
1. Submit a PR.
## Classes within Markdown
This documentation uses a modified version of the [just-the-docs](https://github.com/pmarsceill/just-the-docs) Jekyll theme, which has some useful classes for labels and buttons:
* Labels come in default (blue), green, purple, yellow, and red.
* Buttons come in default, purple, blue, green, and outline.
* Warning, tip, and note blocks are available (`{: .warning }`, etc.).
* If an image has a white background, you can use `{: .img-border }` to add a one pixel border to the image.
These classes can help with readability, but should be used *sparingly*. Each addition of a class damages the portability of the Markdown files and makes moving to a different Jekyll theme (or a different static site generator) more difficult.
Besides, standard Markdown elements suffice for most documentation.
If you want to use the sorts of pretty formulas that [MathJax](https://www.mathjax.org) allows, add `has_math: true` to the Jekyll page metadata. Then insert LaTeX math into HTML tags with the rest of your Markdown content:
```
## Math
Some Markdown paragraph. Here's a formula:
<p>
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are
