+# Proposal automation — one-time org setup
+
+The approval automation in `.github/workflows/` (pipeline / RFC / SIG) is
+self-contained. The project-board `Status` automation below needs a one-time
+configuration step from an **org owner**, because a GitHub Actions / app token
+cannot grant itself project access.
+
+## 1. Issue types (`Pipeline`, `RFC`, `Special Interest Group`) — optional, not currently enabled
+
+Proposals are already distinguished by their template, their
+`new-pipeline` / `new-rfc` / `new-special-interest-group` labels, and their
+separate project boards, so native **issue types** are an optional extra rather
+than a requirement. They are **not** wired up in this repo today.
+
+If you later decide you want them (e.g. for `type:Pipeline` filtering in issue
+search):
+
+1. An org owner creates the types at **github.com/organizations/nf-core/settings/issue-types**, named exactly `Pipeline`, `RFC`, and `Special Interest Group`.
+2. Add the matching `type:` key to each issue-form template, e.g. `type: "Pipeline"` in `new_pipeline.yml`.
+
+> Order matters: the types must exist **before** the templates reference them,
+> otherwise opening an issue from a template with an unknown `type:` fails
+> validation. (The bot token can't manage types itself — it returns
+> `403 Resource not accessible by integration` — which is why this is manual.)
+
+## 2. Project board Status automation
+
+The pipeline workflow now mirrors the approval status onto the
+[pipelines project board](https://github.com/orgs/nf-core/projects/104) — the
+`Status` field is set automatically, replacing the manual curator step that was
+previously documented in the repo README:
+
+| Approval status | Board `Status` option |
+| --------------- | --------------------- |
+| 🕐 Pending      | `proposed`            |
+| ✅ Approved     | `accepted`            |
+| ❌ Rejected     | `turned-down`         |
+| ⏰ Timed Out    | `timed-out`           |
+
+For this to take effect, the bot token (`secrets.nf_core_bot_auth_token`) needs
+**read & write access to organisation projects**:
+
+- Classic PAT: the `project` scope.
+- Fine-grained PAT / app: organisation permission **Projects → Read and write**.
+
+The update is **best-effort**: if the token lacks project access, the `Status`
+field option names don't match, or the issue isn't on the board, the workflow
+logs the reason and continues — the labels and status comment are unaffected.
+The board's `Status` options must be named `proposed`, `accepted`,
+`turned-down`, `timed-out` (they already are); adjust the `PROJECT_STATUS` map
+at the top of `pipeline_proposals.yml` if they ever change.
+
+### Enabling it for the RFC and SIG boards
+
+The same capability is available to the RFC (`nf-core/127`) and SIG
+(`nf-core/105`) workflows. To enable, add the same block near the top of
+`rfc_approval.yml` / `sig_approval.yml`:
+
+```js
+const PROJECT_NUMBER = 127; // 105 for SIG
+const PROJECT_STATUS = {
+  "🕐 Pending": "proposed",
+  "✅ Approved": "accepted",
+  "❌ Rejected": "turned-down",
+  "⏰ Timed Out": "timed-out",
+};
+```
+
+and call `await approvalManager.updateProjectStatus(PROJECT_NUMBER, PROJECT_STATUS[status]);`
+alongside each existing `updateIssueStatus(...)` call. Verify the option names
+on those two boards match first.
