+# Contribute Blog Posts
+
+Fluss uses blog posts to announce releases, explain new technical capabilities, publish design deep-dives, and share community stories.
+
+The website itself lives in the main [apache/fluss](https://github.com/apache/fluss) repository, but blog content is maintained in a separate repository: [apache/fluss-blog](https://github.com/apache/fluss-blog).
+
+This guide explains the simplest contribution flow for blog posts.
+
+## When to Write a Blog Post
+
+Blog posts are a good fit for:
+
+- release announcements
+- deep dives on new features or design choices
+- tutorials and getting-started walkthroughs
+- production stories and user adoption writeups
+- ecosystem updates, integrations, and contributor spotlights
+
+If you are unsure whether an idea belongs in the blog, open a discussion first on [GitHub Discussions](https://github.com/apache/fluss/discussions) or ask on the [developer mailing list](../welcome.mdx#mailing-lists).
+
+## Repository Layout
+
+The [apache/fluss-blog](https://github.com/apache/fluss-blog) repository contains the following important paths:
+
+```text
+blog/
+  authors.yml
+  tags.yml
+  YYYY-MM-DD-my-post.md
+  releases/
+  assets/
+  static/
+```
+
+- `blog/`: the actual post files
+- `blog/releases/`: release announcement posts
+- `blog/assets/`: post-specific diagrams and screenshots
+- `blog/authors.yml`: author metadata
+- `blog/tags.yml`: tag definitions
+- `blog/static/`: shared blog assets such as avatar images
+
+## Contribution Flow
+
+### 1. Discuss the post idea
+
+For release posts or larger technical articles, start by sharing the topic and rough outline with the community. This helps avoid duplicate work and makes it easier to get feedback on scope and timing.
+
+### 2. Fork and clone the blog repository
+
+```bash
+git clone https://github.com/<your-username>/fluss-blog.git
+cd fluss-blog
+```
+
+### 3. Create a branch
+
+```bash
+git checkout -b docs/blog-post-topic
+```
+
+### 4. Create the post file
+
+Create a new Markdown or MDX file under `blog/` using the `YYYY-MM-DD-slug.md` naming pattern:
+
+```text
+blog/2026-05-04-my-post-slug.md
+```
+
+Release announcements usually live under `blog/releases/`.
+
+### 5. Add frontmatter
+
+Every post should begin with frontmatter similar to:
+
+```yaml
+---
+slug: my-post-slug
+title: "My Blog Post Title"
+date: 2026-05-04
+authors: [your-author-key]
+tags: [apache-fluss]
+image: ./assets/my-post/banner.png
+---
+```
+
+Use the `authors` and `tags` keys that are defined in `blog/authors.yml` and `blog/tags.yml`.
+
+### 6. Add media and author metadata
+
+- Put post-specific diagrams and screenshots in `blog/assets/<post-name>/`
+- If you are a new author, add yourself to `blog/authors.yml`
+- Add your avatar image to `blog/static/avatars/` if needed
+- Register any new tags in `blog/tags.yml`
+
+## Writing Guidelines
+
+Try to keep the post:
+
+- technically accurate
+- concrete about the user problem or design tradeoff
+- consistent with Apache project tone
+- easy to scan with headings, code snippets, and diagrams where useful
+
+Good posts usually explain:
+
+1. what problem is being solved
+2. why the change matters
+3. how it works
+4. how readers can try it themselves
+
+## Preview the Blog Locally
+
+From the `fluss-blog` repository:
+
+```bash
+npm install
+npm run start
+```
+
+This starts a local Docusaurus preview so you can check formatting, links, and images before opening a pull request.
+
+## Submit the Pull Request
+
+Once the post is ready:
+
+1. commit the changes with a descriptive message
+2. push the branch to your fork
+3. open a pull request against `apache/fluss-blog`
+
+In the pull request description, include:
+
+- the audience for the post
+- whether it is time-sensitive
+- any images or assets that reviewers should pay special attention to
+
+## How This Connects to the Main Website
+
+The main website repository can pull blog content into local previews through `website/setup_blog.sh`. That is useful when you want to check the post in the full multi-version website context.

 This guide will walk you through the process of contributing to the Fluss documentation, from setting up your environment to submitting your changes.
 
+If you want to contribute a blog post instead of versioned documentation or community pages, use the separate [Contribute Blog Posts](contribute-blog-posts.md) guide. Blog content is maintained in the `apache/fluss-blog` repository rather than in the main website tree.
