+> _For help, support and product questions, head to our [GitHub Community](https://github.com/orgs/GitbookIO/discussions)._

-Thank you for investing your time in contributing to GitBook. Any contribution you make will be reviewed by our team. In this guide, you'll learn the different ways you can contribute.
+Thanks for helping make GitBook better. This repository holds the open source renderer behind every published GitBook site, and the team reads everything that comes in here.

-## Types of Contributions
+## Ways to contribute

-This repository contains code related to the rendering engine of GitBook's published content. Depending on what you'd like to contribute to, head to the section below to find the necessary steps.
+-   **Open an issue.** Report a bug, suggest a feature, or tell us when something feels off. This is the most useful thing you can do.
+-   **Join the conversation.** Share ideas and help others in [GitHub Community](https://github.com/orgs/GitbookIO/discussions).
+-   **Build with GitBook.** Publish your docs, try new features early, and tell us what works and what doesn't.

-### Add a feature
+## Issues instead of pull requests

-Because this portion of GitBook is open source and available for you to use - if you think you can provide extra value through a new feature - you're welcome to add it! If you plan to distribute the code, keep the source code public to comply with GNU GPLv3. To clone in a private repository, you must first acquire a [commercial license](https://www.gitbook.com/pricing).
+Pull requests are limited to the GitBook team. If you've found a bug or want something to change, please [open an issue](https://github.com/GitbookIO/gitbook/issues/new/choose) instead.

-### Create a new issue
+This isn't because we don't want your help. Every change here ships to every published GitBook site, so we need to own each one from start to finish. A clear issue often helps us more than a pull request: it tells us what's wrong and why, and lets us fix it in a way that fits the rest of the codebase.

-If you spot a problem within a repository, [search if an issue already exists](https://docs.github.com/en/github/searching-for-information-on-github/searching-on-github/searching-issues-and-pull-requests#search-by-the-title-body-or-comments). If a related issue doesn't exist, you can open a new issue here!Please make sure any added issues are
+A good issue includes:

-   Descriptive
-   Thoughtful
-   Organized
+-   What you expected to happen, and what happened instead
+-   A link to a published GitBook site that shows the problem, if you have one
+-   Steps to reproduce it, plus screenshots or a recording for anything visual
+-   Your browser and OS, if it looks like it might matter

-We recommend adding as many relevant links, minimal reproductions of the issue, and other materials that will help our team solve the issue fast.
+Before opening one, [search existing issues](https://github.com/GitbookIO/gitbook/issues). If someone has already reported it, add a 👍 or any extra details you have.

-### Solve an issue
+Already fixed it in your fork? Link the branch or commit in your issue. We may open a pull request from it, and your commits keep your name.

-If you're interested in solving an issue in our repository, start by scanning through it's exisiting issues to find one that you're interested in working on. If you find an issue to work on, you are welcome to open a PR with a fix. See the following sections below for more information on contributing for specific sections.
+If you open a pull request anyway, we'll close it and point you here. Nothing personal, and we'd still love the issue.

-### Documentation
+## Reach out

-The official documentation on GitBook open can be found directly in this Readme. Any updates or changes you would like to make, you can make directly to the README of this repository.
+Not sure if it's a bug? Have a half-formed idea? Open an issue or start a [discussion](https://github.com/orgs/GitbookIO/discussions) anyway. We'd much rather hear from you than not, and no report is too small.

-## Contributing
+Spotted a wrong or missing translation? Open an issue with the string and the wording you'd suggest.

-### Make changes locally
+## Using AI

-Any contribution you make can be made to the code located in this repository. In order to contribute, you'll need to start off of a local version of this repository.
+You're welcome to use AI to help you write an issue. Please read and check what it produces before you post: reports that are long, vague or unverified take time away from fixing real problems, and we may close them without a reply.

+[GitbookIO/slack-pr-status](https://github.com/GitbookIO/slack-pr-status) adds review-status reactions to PR links posted in [#engineering](https://gitbook.slack.com/archives/C01NXGWJELS). It runs from `.github/workflows/slack-pr-status.yml` in `GitbookIO/gitbook`, `GitbookIO/gitbook-x` and `GitbookIO/integrations`. Emojis and statuses are configured in that workflow; see the action's README for the options.

+Posts that link PRs from more than one repository are skipped, because each workflow's token can only read its own repository. PRs from forks get no reactions, because their workflows don't receive secrets.

-# Slack PR reactions
-
-[DataDog/slapr](https://github.com/DataDog/slapr) updates reactions on existing PR-link messages in [#engineering](https://gitbook.slack.com/archives/C01NXGWJELS). It runs in GitHub Actions. It does not post messages, approve or merge PRs, or change branch protection.
-
-## Rollout and ownership
-
-Owner: Peter White.
-
-The rollout targets `GitbookIO/gitbook` (GBO), `GitbookIO/gitbook-x` (GBX), and `GitbookIO/integrations`. Each repository contains `.github/workflows/slapr.yml` and this runbook.
-
-| Configuration | Value |
-| --- | --- |
-| Channel | `#engineering`, `C01NXGWJELS` |
-| App manifest | `.github/slapr-app-manifest.json` |
-| Slack app ID | `A0C2AGLAD0T` |
-| Bot user ID | `U0C2AGP16R1`, repository variable `SLAPR_BOT_USER_ID` |
-| Bot token | Repository Actions secret `SLAPR_SLACK_BOT_TOKEN` |
-| Action | `DataDog/slapr@1c074e1dfd433f91a679d5113f7f8b956b65d973` |
-| Approval threshold | Stock default, one approval |
-| Events | `pull_request_review: submitted`, `pull_request: closed` |
-
-## Install and configure
-
-1. In [Slack app management](https://api.slack.com/apps), create the **PR Status** app from `.github/slapr-app-manifest.json` in the GitBook workspace. Obtain workspace approval if required, then install it. The bot requests Slapr's documented `channels:history`, `reactions:read`, and `reactions:write` scopes. `#engineering` is public, so `groups:history` is unnecessary. No review map is configured, so `channels:read` is unnecessary.
-2. Invite **PR Status** only to `#engineering`. Keep it dedicated to Slapr: stock Slapr removes obsolete reactions belonging to this bot on a matched message. It leaves other users' reactions alone.
-3. Record the app ID and bot user ID above. The bot profile's member ID or Slack `auth.test` response's `user_id` is the required bot user ID, not the app ID or bot ID.
-4. Store the bot OAuth token as `SLAPR_SLACK_BOT_TOKEN` in each of the three repositories' Actions secrets. Use the GitHub secret UI or `gh secret set SLAPR_SLACK_BOT_TOKEN --repo GitbookIO/<repository>` and its hidden prompt. Never paste the token into a command argument, chat, workflow, or committed file. Alternatively, an organization secret must use selected-repository visibility limited to these three repositories.
-5. Set Actions variable `SLAPR_BOT_USER_ID` in each repository to that bot's user ID. The token and user ID must belong to the same installation. Use `gh variable set SLAPR_BOT_USER_ID --repo GitbookIO/<repository> --body '<user-id>'` or the GitHub UI.
-6. Merge the workflows through normal review, then run the live checks below. Repository maintainers handle reviews and merges; Slapr has only read access to GitHub contents and pull requests.
-
-GBX runs this workflow on `blacksmith-2vcpu-ubuntu-2404`. GBO and integrations use `ubuntu-latest`, matching their existing workflows.
-
-The workflow hardcodes the engineering channel and does not check out PR code. It uses the stock event triggers and leaves the approval threshold unset. There are no listeners, schedules, review maps, custom discovery, or additional services.
-
-## Reactions
-
-Slapr's status selection stays unchanged. Missing custom emoji names are mapped through the action's supported inputs to existing equivalents. Workspace lookup on 2026-09-17 confirmed `pr-approved` and `merged`; the other mappings are standard Slack emojis.
-
-| Stock status | Reaction |
-| --- | --- |
-| Review started | `:eyes:` |
-| Partially approved | `:next_track_button:` |
-| Approved | `:pr-approved:` |
-| Changes requested | `:construction:` |
-| Merged | `:merged:` |
-| Closed without merging | `:no_entry_sign:` |
-| Comment-only review | `:speech_balloon:` |
-
-The partially-approved reaction is configured but cannot occur with the default threshold of one approval. It becomes relevant only if that threshold is raised.
-
-On approval, expect review-started and approved reactions. On merge, stock Slapr removes review-started and adds merged; it can retain approved alongside merged. Approval and merging have distinct reactions. Other stock review-state behavior is accepted.
-
-## Live acceptance test
-
-For each repository after credentials are configured and the workflow is on the default branch:
-
-1. Open a fresh same-repository test PR through normal review. Post its full `https://github.com/GitbookIO/<repository>/pull/<number>` link as a new top-level message in `#engineering` before the review event.
-2. Have another contributor approve it. Open the **Slack PR reactions** Actions run and verify that the matched message has the bot's `pr-approved` reaction.
-3. Have an authorized maintainer merge it. Verify the closed-event run succeeds and the same message has the bot's `merged` reaction. No new Slack status message should appear.
-4. Record the PR URL, Slack message permalink, approval/merge workflow run URLs, date, and result below. A green workflow alone does not prove the message was found or reacted to.
-
-| Repository | PR and Slack message | Approval run/result | Merge run/result |
-| --- | --- | --- | --- |
-| GitbookIO/gitbook | Pending | Not tested | Not tested |
-| GitbookIO/gitbook-x | Pending | Not tested | Not tested |
-| GitbookIO/integrations | Pending | Not tested | Not tested |
-
-Only the first matching message in Slapr's recent-history response is updated. Older messages, thread replies, duplicate posts, fork PRs, and links posted after the event are outside this rollout's acceptance criteria. Slapr does not paginate history or reconcile missed events.
-
-## Troubleshoot and disable
-
- No workflow run: confirm the workflow is merged, Actions permits the pinned action, and the event was a submitted review or PR closure. These are the only configured triggers.
- `No message found requesting review`: confirm the full PR link was posted as a recent top-level message in `#engineering` before the event. This is a successful no-op in stock Slapr.
- `not_in_channel` or `channel_not_found`: check the app installation, channel ID, and bot membership in `#engineering`.
- `missing_scope`: compare the installed bot scopes with the manifest and reinstall after changes.
- `invalid_auth` or `account_inactive`: replace the repository secrets with the current bot token. If the bot identity changed, update `SLAPR_BOT_USER_ID` too.
- `invalid_name`: check the emoji mappings still exist. If a custom emoji was removed, map that input to another existing emoji, keeping approval and merged distinct.
- Old reactions remain or removal fails: confirm `SLAPR_BOT_USER_ID` is the member ID for the token's bot.
- GitHub permission errors: keep `contents: read` and `pull-requests: read`; do not introduce a PAT, write permissions, or `pull_request_target` to cover forks. Fork and Dependabot secret restrictions are accepted limitations.
- Rate limits or transient API failures: inspect the Actions log and retry the failed run after the limit resets. There is no scheduled reconciliation.
-
-Disable one repository with `gh workflow disable slapr.yml --repo GitbookIO/<repository>`, or disable **Slack PR reactions** in its Actions UI. Repeat for all three to stop the integration. Revoke the Slack app token to stop its access immediately, remove its repository secrets, and remove the bot from `#engineering` when retiring it. Existing reactions remain.
-
-## Pin review
-
-On 2026-09-17, the pinned action definition, Dockerfile, entry point, dependency declarations, GitHub reads, Slack history lookup and reaction writes were inspected. Without `review-map`, the action targets only the supplied channel. It reads PR/review state and adds/removes reactions; it does not post Slack messages or write to GitHub.
-
-The action SHA pins Slapr's source. Its upstream Dockerfile still uses the mutable `python:3.14` image and installs dependencies, including `pyyaml>=5.0`, at build time. This rollout keeps stock Slapr unchanged. Review upstream source and dependency changes before updating the SHA in all three repositories.
