+# 📤 RN Publish
+
+> For an overview of all available workflows, see the [main README](../README.md).
+
+**Publishes a reviewed release note comment to the Skyline Collaboration platform**
+
+The [RN Publish workflow](../workflows/rn-publish.yml) triggers when the `rn-publish` label is added to a pull request. It finds all `## 📋 Release Note` comments on the PR, converts the Markdown body to HTML, and posts each one to the Skyline Collaboration API (`api.skyline.be/api/ReleaseNotes`). Re-triggering the label updates existing entries rather than creating duplicates.
+
+## Installation
+
+### 1. Copy the workflow file
+
+Copy [`workflows/rn-publish.yml`](../workflows/rn-publish.yml) into the `.github/workflows/` folder of the target repository.
+
+### 2. Add the required secrets
+
+Go to **Repository → Settings → Secrets and variables → Actions → Repository secrets** and add:
+
+| Secret | Value |
+|--------|-------|
+| `COLLABORATION_USERNAME` | Your Skyline Collaboration platform username |
+| `COLLABORATION_PASSWORD` | Your Skyline Collaboration platform password |
+
+### 3. Create the `rn-publish` label
+
+```bash
+gh label create rn-publish --color 0075ca --description "Publish the release note to the collaboration platform"
+```
+
+Or via **GitHub → Repository → Issues → Labels → New label**.
+
+### 4. (Optional but recommended) Set the `SOLUTION_NAME` variable
+
+If this repository belongs to a named Solution (e.g. InfraOps), set a repository variable so the published entry is correctly categorised on the platform.
+
+Go to **Repository → Settings → Secrets and variables → Actions → Repository variables** and add:
+
+| Variable | Value |
+|----------|-------|
+| `SOLUTION_NAME` | The exact solution name as it appears in the collaboration platform (e.g. `InfraOps`) |
+
+When `SOLUTION_NAME` is set, the workflow automatically populates `Application: "Solutions"` and `Functionality: [<SOLUTION_NAME>]` in the API payload. When absent, those fields are omitted and the entry is published without a solution category.
+
+## How it works
+
+### Activation
+
+Add the `rn-publish` label to a pull request that has one or more `## 📋 Release Note` comments (produced by the [RN Write](rn-write.md) workflow or written manually). The label triggers the workflow; the label is removed again when publishing completes.
+
+### Processing
+
+For each `## 📋 Release Note` comment found on the PR:
+
+1. **Validates** the required fields (`**Type:**`, `**Breaking Change:**`).
+2. **Extracts** the description body (everything after the metadata header) and **converts it from Markdown to HTML** via `pandoc` so the collaboration platform's rich-text editor renders it correctly — paragraphs, bullet lists, `inline code`, **bold**, and *italic* are all preserved.
+3. **Looks up `SolutionVersion`** — fetches the latest non-draft GitHub release whose `target_commitish` matches the PR's base branch and uses its tag name. Silently omitted when no matching release exists.
+4. **Derives `Scope`** from the `Type` field automatically (see table below).
+5. **Calls the API** — POST for a new entry, PATCH if the comment already contains an `<!-- rn-published: {id} -->` marker (idempotent re-publish).
+6. **Edits the comment** to append a ✅ line with the published URL and the invisible `<!-- rn-published: {id} -->` marker.
+
+After all entries are processed, the `rn-proposal` and `rn-publish` labels are removed and the `rn-published` label is applied to the PR.
+
+### API fields
+
+| Field | Source | Notes |
+|-------|--------|-------|
+| `Title` | `**Title:**` in the comment | Falls back to the PR title for comments that predate the Title field |
+| `Description` | Comment body (below the metadata header) | Converted from GFM Markdown to HTML via `pandoc -f gfm -t html --wrap=none` |
+| `Type` | `**Type:**` in the comment | Must be one of `New Feature/Enhancement`, `Bug Fix`, or `Release Notes` |
+| `BreakingChange` | `**Breaking Change:**` in the comment | Must be `true` or `false` |
+| `Scope` | Derived from `Type` — see table below | Always included |
+| `Application` | Hardcoded `"Solutions"` | Only included when `SOLUTION_NAME` is set |
+| `Functionality` | `[<SOLUTION_NAME>]` | Only included when `SOLUTION_NAME` is set |
+| `SolutionVersion` | Tag name of the latest non-draft GitHub release for the PR's base branch | Omitted when no matching release exists |
+| `InternalComments` | PR URL (`https://github.com/<repo>/pull/<number>`) | Always included |
+
+### Scope mapping
+
+The `Scope` field is derived automatically — no manual input needed:
+
+| Type | Scope |
+|------|-------|
+| `Bug Fix` | `Regression only` |
+| `New Feature/Enhancement` | `Functional` |
+| `Release Notes` | `Functional` |
+
+The logic here is that a bug fix restores previous behavior (regression scope), while a new feature or enhancement adds or changes functional behavior.
+
+### Idempotency
+
+Each published comment is edited to include an invisible HTML marker:
+
+```
+<!-- rn-published: 12345 -->
+```
+
+If the `rn-publish` label is added again later, the workflow detects this marker, looks up the existing entry by ID, and issues a PATCH request to update it — no duplicate entries are created.
+
+## What it reads
+
+- All PR comments matching `## 📋 Release Note`
+- The PR's base branch (for `SolutionVersion` lookup)
+- GitHub releases for the repository (for `SolutionVersion`)
+
+## What it creates or updates
+
+- **Entries on the Skyline Collaboration platform** — one per matching comment
+- **Edits each comment** to append the published URL and idempotency marker
+- **Removes** the `rn-proposal` and `rn-publish` labels
+- **Applies** the `rn-published` label to the PR
+
+## Manual release notes
+
+The `## 📋 Release Note` heading is all the publish workflow looks for. This means anyone can manually write a release note comment on any PR using the structure below — the agentic `rn-write` workflow does not have to be active in the repository:
+
+```markdown
+## 📋 Release Note
+
+**Title:** A short changelog title
+**Type:** New Feature/Enhancement
+**Breaking Change:** false
+
+The description of the change, written in plain Markdown. Use paragraphs,
+bullet lists, `inline code`, **bold**, and *italic* freely — they will be
+converted to HTML before being sent to the platform.
+```
+
+## Troubleshooting
+
+| Symptom | Cause | Fix |
+|---------|-------|-----|
+| `❌ Missing required secrets` | `COLLABORATION_USERNAME` or `COLLABORATION_PASSWORD` not set | Add them as repository secrets |
+| `❌ No release note draft found` | No `## 📋 Release Note` comment on the PR | Run the `rn-write` workflow or add a comment manually |
+| `❌ could not find **Type:**` | Comment is missing the `**Type:**` field | Edit the comment to add a valid Type |
+| `❌ invalid Type` | Type is not one of the accepted values | Must be `New Feature/Enhancement`, `Bug Fix`, or `Release Notes` |
+| `❌ Skyline API update failed` | Authentication or API error | Check secrets; inspect the HTTP status and message in the error comment |
+| Description renders as one block on the platform | Old version of the workflow without pandoc | Update to the latest `rn-publish.yml` |
