-# Contributing to documentation
-
-We welcome contributions to Netdata's already extensive documentation.
-
-We store documentation related to the open-source Netdata Agent inside of the [`netdata/netdata`
-repository](https://github.com/netdata/netdata) on GitHub. Documentation related to Netdata Cloud is stored in a private
-repository and is not currently open to community contributions.
-
-The Netdata team aggregates and publishes all documentation at [learn.netdata.cloud](https://learn.netdata.cloud/) using
-[Docusaurus](https://v2.docusaurus.io/) in a private GitHub repository.
-
-## Before you get started
-
-Anyone interested in contributing to documentation should first read the [Netdata style
-guide](https://github.com/netdata/netdata/blob/master/docs/contributing/style-guide.md) and the [Netdata Community Code of Conduct](https://github.com/netdata/.github/blob/main/CODE_OF_CONDUCT.md).
-
-Netdata's documentation uses Markdown syntax. 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.
-
-### Netdata's documentation structure
-
-Netdata's documentation is separated into four sections.
-
-- **Netdata**: Documents based on the actions users want to take, and solutions to their problems, such both the Netdata
-  Agent and Netdata Cloud.
-  - Stored in various subfolders of the [`/docs` folder](https://github.com/netdata/netdata/tree/master/docs) within the
-    `netdata/netdata` repository: `/docs/collect`, `/docs/configure`, `/docs/export`, `/docs/get`, `/docs/monitor`,
-    `/docs/overview`, `/docs/quickstart`, `/docs/store`, and `/docs/visualize`.
-  - Published at [`https://learn.netdata.cloud/docs`](https://learn.netdata.cloud/docs).
-- **Netdata Agent reference**: Reference documentation for the open-source Netdata Agent.
-  - Stored in various `.md` files within the `netdata/netdata` repository alongside the code responsible for that
-    feature. For example, the database engine's reference documentation is at `/database/engine/README.md`.
-  - Published under the **Reference** section in the Netdata Learn sidebar.
-- **Netdata Cloud reference**: Reference documentation for the closed-source Netdata Cloud web application.
-  - Stored in a private GitHub repository and not editable by the community.
-  - Published at [`https://github.com/netdata/netdata/blob/master/docs/cloud/cloud.mdx`](https://github.com/netdata/netdata/blob/master/docs/cloud/cloud.mdx).
-- **Guides**: Solutions-based articles for users who want instructions on completing a specific complex task using the
-  Netdata Agent and/or Netdata Cloud.
-  - Stored in the [`/docs/guides` folder](https://github.com/netdata/netdata/tree/master/docs/guides) within the
-    `netdata/netdata` repository. Organized into subfolders that roughly correlate with the core Netdata documentation.
-  - Published at [`https://learn.netdata.cloud/guides`](https://learn.netdata.cloud/guides).
-
-Generally speaking, if you want to contribute to the reference documentation for a specific Netdata Agent feature, find
-the appropriate `.md` file co-located with that feature. If you want to contribute documentation that spans features or
-products, or has no direct correlation with the existing directory structure, place it in the `/docs` folder within
-`netdata/netdata`.
-
-## How to contribute
-
-The easiest way to contribute to Netdata's documentation is to edit a file directly on GitHub. This is perfect for small
-fixes to a single document, such as fixing a typo or clarifying a confusing sentence.
-
-Click on the **Edit this page** button on any published document on [Netdata Learn](https://learn.netdata.cloud). Each
-page has two of these buttons: One beneath the table of contents, and another at the end of the document, which take you
-to GitHub's code editor. Make your suggested changes, keeping [Netdata style guide](https://github.com/netdata/netdata/blob/master/docs/contributing/style-guide.md)
-in mind, and use *Preview changes** button to ensure your Markdown syntax works as expected.
-
-Under the **Commit changes**  header, write descriptive title for your requested change. Click the **Commit changes**
-button to initiate your pull request (PR).
-
-Jump down to our instructions on [PRs](#making-a-pull-request) for your next steps.
-
-### Edit locally
-
-Editing documentation locally is the preferred method for complex changes that span multiple documents or change the
-documentation's style or structure.
-
-Create a fork of the Netdata Agent repository by visit the [Netdata repository](https://github.com/netdata/netdata) and
-clicking on the **Fork** button. 
-
-![Screenshot of forking the Netdata
-repository](https://user-images.githubusercontent.com/1153921/59873572-25f5a380-9351-11e9-92a4-a681fe4a2ed9.png)
-
-GitHub will ask you where you want to clone the repository. When finished, you end up at the index of your forked
-Netdata Agent repository. Clone your fork to your local machine:
-
-```bash
-git clone https://github.com/YOUR-GITHUB-USERNAME/netdata.git
-```
-
-Create a new branch using `git checkout -b BRANCH-NAME`. Use your favorite text editor to make your changes, keeping the
-[Netdata style guide](https://github.com/netdata/netdata/blob/master/docs/contributing/style-guide.md) in mind. Add, commit, and push changes to your fork. When
-you're finished, visit the [Netdata Agent Pull requests](https://github.com/netdata/netdata/pulls) to create a new pull
-request based on the changes you made in the new branch of your fork.
-
-## Making a pull request
-
-Pull requests (PRs) should be concise and informative. See our [PR guidelines](https://learn.netdata.cloud/contribute/handbook#pr-guidelines) for
-specifics.
-
-- The title must follow the [imperative mood](https://en.wikipedia.org/wiki/Imperative_mood) and be no more than ~50
-  characters.
-- The description should explain what was changed and why. Verify that you tested any code or processes that you are
-  trying to change.
-
-The Netdata team will review your PR and assesses it for correctness, conciseness, and overall quality. We may point to
-specific sections and ask for additional information or other fixes.
-
-After merging your PR, the Netdata team rebuilds the [documentation site](https://learn.netdata.cloud) to publish the
-changed documentation.

-### 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.
-
-For example, here is the frontmatter for the guide
-about [deploying the Netdata Agent with Ansible](https://github.com/netdata/netdata/blob/master/docs/guides/deploy/ansible.md).
-
-```markdown

-
-### 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 `https://github.com/netdata/netdata/blob/master/docs/configure/nodes.md`. To reference
-the guide for deploying the Netdata Agent with Ansible, link to `/docs/guides/deploy/ansible.md`.

+### Adding Notes
+
+Notes inside files should render properly both in GitHub and in Learn, to do that, it is best to use the format listed below:
+
+```
+> ### Note
+> This is an info or a note block.
+
+> ### Tip, Best Practice
+> This is a tip or a best practice block.
+
+> ### Warning, Caution
+> This is a warning or a caution block.

+### Tabs
+
+Docusaurus allows for Tabs to be used, but we have to ensure that a user accessing the file from GitHub doesn't notice any weird artifacts while reading. So, we use tabs only when necessary in this format:
+
+```
+
+<Tabs>
