+## Edit content in your browser
+
+You do not need to install Git or Hugo to fix text or a broken link. Find the relevant Markdown page under [`content/`](https://github.com/forrtproject/forrtproject.github.io/tree/main/content), open it on GitHub, and choose the pencil icon. GitHub will guide you through creating a fork, committing the edit, and opening a pull request against `main`.
+
+Preserve the YAML/TOML front matter at the top of the file and existing Hugo shortcodes. Describe the affected page and link to it in your PR. Generated paths include `content/curated_resources/` (except `_index.md`), `content/glossary/`, `content/contributors/tenzing.md`, `content/contributor-analysis/`, `content/publications/citation_chart.webp`, announcement bundles in `content/post/`, `content/replication-hub/flora/_index.md`, `static/data/fred_citation.txt`, and generated files in `data/`. The manually maintained `data/publications.yaml` is editable; follow the [publication instructions](content/publications/README). Generated content is refreshed during deployment. Use the source submission form/sheet linked from the public page or open an issue rather than editing the generated output. Local previews use committed copies and can differ from production. For layout or code changes, use the local setup below.

 ## Contribution Workflow
 
+For browser edits, GitHub handles branch creation and opening the PR; see [staging guidance](#how-staging-works) to request a preview.

 All proposed changes must be made on a feature branch and submitted via a Pull Request to `main`. We do not use a separate development branch.
 
 1. **Fork and clone** — fork the repository to your account and clone it locally (if you haven't already).

+   git switch main
+   git merge --ff-only upstream/main

Run `hugo --gc --minify --cleanDestinationDir --destination public` to check a production-style build; do not commit the generated `public/` output. Browser-only contributors can state that they could not run a local build and request a maintainer preview.
 
 4. **Commit with a clear message** — describe what you changed and why:
 
    ```bash
    git commit -m "Fix broken link in contributing guide"
    ```
 
-5. **Push and open a Pull Request** — push your branch and open a PR targeting the `main` branch of `forrtproject/forrtproject.github.io`. Link any related issues and briefly summarise your changes.

 ### How Staging Works
 
-When a PR is opened, synchronised, or reopened, the staging workflow:
+Automatic staging collects open, non-draft PRs targeting `main` and merges them in sequence onto a temporary branch. Conflicting PRs are skipped and logged. Inclusion in staging does not mean a PR has passed review or been approved for merging. The workflow posts staging results to PRs and retains two recent staging branches.
 
-1. **Aggregates open PRs** — collects all non-draft PRs targeting `main` and merges them in sequence onto a temporary branch.
-2. **Handles conflicts gracefully** — PRs that merge cleanly are included; conflicting PRs are skipped and logged.
-3. **Posts a deployment comment** on each PR:
-   - ✅ Successfully included in staging
-   - ⚠️ Skipped due to merge conflicts
-4. **Manages concurrency** — builds are queued (not cancelled) with job timeouts of 10–20 minutes.
-5. **Cleans up old branches** — keeps only the 5 most recent staging branches.
+**External forks cannot trigger their own staging deployment.** GitHub withholds repository secrets from fork-triggered runs, so those runs fail with an explanatory message instead of deploying. Fork PRs can still appear in the next aggregate build triggered by a same-repository PR or the monthly schedule. For an earlier preview, ask a maintainer in your PR. The maintainer runs **Actions → Staging Aggregate Deployment → Run workflow** from the upstream `main` branch and enters the PR number in `single_pr`. The workflow resolves the public fork automatically; the maintainer does not need to select the fork branch. This previews the selected PR rather than the full aggregate, and replaces the shared staging site until the next staging deployment.
 
 ### Monthly Reports
 
 On the 1st of each month, an automated GitHub issue is created with:
 
 - Total PRs processed
 - Successfully merged PRs
-- Skipped PRs (with conflict details)
-- Deployment statistics
+- Skipped PR numbers (labelled as merge conflicts), when at least one attempted PR was included; the current report omits this list if all attempts fail
+- Aggregate branch and deployment time
