+## 📰 Blog & Feed content
+
+There are two markdown-driven content sections on this site:
+
+- **Blog** (`content/blog/`) — long-form articles, product releases and case studies. Published at `/blog/`.
+- **Feed** (`content/feed/`) — short announcements and social-media style updates. Published at `/feed/`.
+
+Both sections are combined into a single RSS feed at [`/rss.xml`](https://datacontroller.io/rss.xml).
+
+See [`docs/adding-feed-posts.md`](docs/adding-feed-posts.md) for a step-by-step guide on adding a new Feed post.

+# Welcome to the Feed
+
+We're launching a new **Feed** section on the Data Controller website! This is where you'll find:
+
+- Quick announcements
+- Social media style updates
+- Smaller news items that don't warrant a full blog post
+
+It sits alongside our [Blog](/blog/) and both are combined into a single [RSS feed](/rss.xml) so you can subscribe once and get everything in one place.
+
+Stay tuned for more updates!

+# Adding a Feed Post
+
+The **Feed** section (`/feed/`) is for short announcements and social-media
+style updates — things that don't warrant a full [`content/blog/`](../content/blog)
+article, but are still worth publishing and syndicating via RSS.
+
+Feed posts work exactly like blog posts (one markdown file per post, in its
+own directory), but live under `content/feed/` instead of `content/blog/`,
+and are published under `/feed/` instead of `/blog/`.
+
+Both sections share a single combined RSS feed at
+[`/rss.xml`](https://datacontroller.io/rss.xml) (see `gatsby-plugin-feed` in
+[`gatsby-config.js`](../gatsby-config.js)), so a new Feed post automatically
+appears in the RSS feed the next time the site is built — no extra
+configuration required.
+
+A visible "RSS Feed" link (pointing to `/rss.xml`) is rendered in two places
+so visitors can discover and subscribe to it:
+
+- The site-wide [`Footer`](../src/components/footer/index.tsx), under
+  "Other Resources".
+- The "Subscribe" section of the shared
+  [`SideBar`](../src/templates/sidebar.tsx), shown on Blog and Feed list/post
+  pages.
+
+## 1. Create a new post directory
+
+Create a new folder under `content/feed/`, named after the post slug (this
+becomes the URL):
+
+```
+content/feed/my-new-announcement/index.md
+```
+
+## 2. Write the frontmatter + content
+
+```md
+---
+title: 'My New Announcement'
+description: A one or two sentence summary used for SEO and RSS.
+date: '2024-06-01 09:00:00'
+author: 'Your Name'
+authorLink: https://www.linkedin.com/in/yourprofile/
+tags:
+  - Announcements
+---
+
+Your announcement content goes here, written in regular Markdown.
+```
+
+Notes on frontmatter fields:
+
+| Field         | Required | Notes                                                                 |
+| ------------- | -------- | ---------------------------------------------------------------------- |
+| `title`       | Yes      | Post title, used on the page, in the sidebar and in the RSS item.      |
+| `description` | Yes      | Short summary, used for SEO meta tags and the RSS item description.    |
+| `date`        | Yes      | Format `'YYYY-MM-DD HH:MM:SS'`. Controls sort order and the archive.   |
+| `author`      | Yes      | Displayed under the post title.                                        |
+| `authorLink`  | No       | If set, the author name links out (e.g. to a LinkedIn profile).        |
+| `tags`        | Yes      | One or more tags. Used for the sidebar category list and RSS `<category>`. |
+| `previewImg`  | No       | Optional relative path to an image in the same folder (e.g. `'./cover.png'`). Feed posts commonly omit this since they're short-form. |
+
+## 3. Add any images (optional)
+
+If you use `previewImg` or reference images in the body, place the image
+files in the same post directory and reference them with a relative path,
+the same as for blog posts.
+
+## 4. Build / preview
+
+```shell
+npm run develop
+```
+
+Your new post will be available at `/my-new-announcement/`, and will appear:
+
+- On the [`/feed/`](https://datacontroller.io/feed/) listing page (with
+  pagination, sidebar archives and tag categories under `/feed/...`).
+- In the site search index.
+- In the combined RSS feed at `/rss.xml`, alongside blog posts.
+
+## How it differs from a Blog post
+
+| Aspect            | Blog                          | Feed                              |
+| ------------------ | ------------------------------ | ----------------------------------- |
+| Content directory  | `content/blog/`                | `content/feed/`                     |
+| Listing page        | `/blog/`                       | `/feed/`                            |
+| Year archive        | `/{year}/`                     | `/feed/{year}/`                     |
+| Category page       | `/category/{tag}/`             | `/feed/category/{tag}/`             |
+| Template            | `src/templates/blog-post.tsx`, `src/templates/blog-list.tsx` | `src/templates/feed-post.tsx`, `src/templates/feed-list.tsx` |
+| RSS                 | Included in `/rss.xml`         | Included in `/rss.xml`              |
+
+Feed archive/category routes are prefixed with `/feed/` specifically to avoid
+colliding with the equivalent Blog routes, since both content types are
+rendered by the shared [`src/templates/sidebar.tsx`](../src/templates/sidebar.tsx)
+component (via its `basePath` prop).
