+# HedgeDoc-HedgeAgent
+
+This is a customized version that makes it possible to invite an AI agent to a note via the menu. "Invite Agent" sends the `note_id` to hedgeagent.

+To start an instance for development, the following is required:
+1. ```cp config.json.example config.json ```
+2. Update ```"domain": "change this" ```
+3. ```.yarn/releases/yarn-4.12.0.cjs install```
+4. ```.yarn/releases/yarn-4.12.0.cjs run build```
+5. ```.yarn/releases/yarn-4.12.0.cjs start```
+
+To start for production:
+1. `docker compose up -d`
+
+Note: Use UID 10000 for data folders.

  - [ ] Release PR in <https://github.com/hedgedoc/container>
-    - [ ] Update version in `.github/workflows/release.yml`
-    - [ ] Update version in `docker-compose.yml`
  - [ ] Release PR in <https://github.com/hedgedoc/social-media>
 - [ ] Security fixes (make sure all available undisclosed security fixes are merged)

-  2. Start HedgeDoc 1 with filesystem uploads and a Postgres DB locally.
-  3. Create a new note and upload an image. The image should be now in the uploads directory.
-  4. Stop HedgeDoc. Update the config to configure a Minio instance (minio and s3bucket keys in config.json). Ensure the config on the Minio instance is existing (valid access key and secret, bucket existing and empty).
-  5. Run `bin/migrate_fs_to_minio`.
-  6. Start the HedgeDoc again. The note with the previously uploaded image should now contain the new image URL. The image should load.

-# How to make your HedgeDoc instance production ready
-
-If you run your own HedgeDoc instance at one point you should probably consider a few things and how you want to handle them.
-In this guide we try to show you a few of those considerations and want to discuss what's best to do.
-
-## Node Env
-
-You want to start HedgeDoc with `NODE_ENV=production`. This tells HedgeDoc to run in production, log a bit less and use the production configuration in your config.json.
-
-## HTTPS
-
-You want to configure a reverse proxy that handles your HedgeDoc TLS termination. For this you should consult the [reverse proxy guide](reverse-proxy.md).  
-Look also at the hsts options in our [configuration](../configuration.md#web-security-aspects) to specify what works for your setup.
-
-## Uploads
-
-Depending on your instance and your expected amount of usage you may want to configure a different upload backend or at the very least configure external monitoring for the filesystem folder where HedgeDoc should put uploads to account for any sudden increases in usage.
-
-## Database
-
-We strongly recommend you use a different database than SQLite for your production instance. If you're a single user instance this is probably fine, but a database server is typically more robust than a single sqlite.db file.
-
-## Login
-
-You should configure a production ready user backend. This can either be via LDAP, SAML or OAuth2 or you use one of HedgeDoc preset configurations for e.g. GitHub. Our username / password system works, but lacks many functionalities you probably want like two-factor-auth or self-service password resets. 
-
-## Guest Users
-
-When HegdeDoc was first written the internet was a different place. Back then allow anonymous usage of a service like HedgeDoc seemed like a cool idea.
-Unfortunatly we don't live in that time anymore and anonymous usage is probably not the best idea anymore.  
-To prevent anonyomous usage you should set `allowAnonymous` or `CMD_ALLOW_ANONYMOUS` to `false`. After that anonymous users are not able to create any notes.
-You could set `allowAnonymousEdits` or `CMD_ALLOW_ANONYMOUS_EDITS` to `true` to allow anonymous users to edit pages where the note owner explicity allowed this.
-
-## Default Note Permission
-
-Depending on your needs to may want to change the default permissions of notes to something more strict. Per default everybody expect guests can write to the notes, but you may want to have a different default. See [this table](../references/permissions.md) to understand the different options.
-Regardless of what you chose here, the users will be able to change this behavior.
-
-## Metrics
-
-Please be aware that HedgeDoc exposes a few metric endpoints `/status`, `/_health` and `/metrics`. You either want to disable the more verbose of these endpoints (`/status` and `/metrics`) via `enableStatsApi` or `CMD_ENABLE_STATS_API` or configure your reverse proxy to only route these endpoints to a private network that your metrics grabber has access to.
-
-## Backup
-
-We recommend keeping backups of your instance in case something fails allong the lines. These backups should include:
-
- Your database
- Your uploads
- Your configuration

-# Permissions
-
-HedgeDoc 1.x uses a basic permission system that differentiates between the owner of a note (the account who initially
-created it), logged-in users and guests.
-
-It is possible to change the access permission of a note through the little button on the top right of the view pane
-in the editor. However, only the note owner can change the permission of a note.
-
-The permissions are named **Freely**, **Editable**, **Limited**, **Locked**, **Protected** and **Private**.
-
-You can configure the default permission for new notes using the `defaultPermission` option in the `config.json` file or
-`CMD_DEFAULT_PERMISSION` environment variable.
-
-For more information, see the [configuration documentation](../configuration.md#users-and-privileges).

 # Release Notes

-## <i class="fa fa-tag"></i> 1.x.x <i class="fa fa-calendar-o"></i> UNRELEASED
-
-### Enhancements
-
- Automatically skip the login modal if no form-based login and exactly one external login provider is configured
-
-### Bugfixes
-
- All links will be opened in new tabs instead of the same tab as the note. This was changed when the external link warning was implemented and now the old behavior is restored.
- Fixed multiple bugs in the realtime connection handling that could lead to data-loss of users with a flaky connection
-
-## <i class="fa fa-tag"></i> 1.11.1 <i class="fa fa-calendar-o"></i> 2026-07-24
-
-### Security fixes
-
- [GHSA-93w7-49m2-cqwg](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-93w7-49m2-cqwg) reports possible corruption of permission values due to missing validation. This should not impact permission checks, except when the note owner intentionally set their note permission to something invalid.
-
-### Enhancements
-
- Added external link warning setting (`externalLinkWarning` in config.json or `CMD_EXTERNAL_LINK_WARNING`) to disable the external link warning page entirely
- Added external link whitelist setting (`externalLinkWhitelist` in config.json or `CMD_EXTERNAL_LINK_WHITELIST`) to skip warning page for certain domains
- Added support for webp file uploads (for all backends except `imgur`, since that does not support these)
-
-### Bugfixes
-
- Fixed external link warning for subpath instances
- Restore native browser zoom-in keyboard shortcuts in the editor
- Nested list items render properly again in the preview pane for slides
-
-### Refactoring / Clean-up
-
- Removed the old Temp database object and related API endpoints. This was used by a very old way of migrating the history and is no longer needed.
- Removed unused `allowOrigin` (environment variable `CMD_ALLOW_ORIGIN`) config option.
- Removed unnecessary/duplicate entries in the XSS filtering whitelist

-## <i class="fa fa-tag"></i> 1.11.0 <i class="fa fa-calendar-o"></i> 2026-06-18
-
-### Security fixes
-
-This release contains four security fixes:
- [CVE-2026-58487](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-6c2w-8w96-3pcv) reports a possible HTML injection via the localpart of an email address.
- [CVE-2026-58486](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-qj78-mjch-wwrv) reports a possible Denial-of-Service attack using the YAML frontmatter parsing.
- [CVE-2026-58489](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-8v9p-5j95-826j) reports a possible CSRF attack vector in the GitHub Gist export.
- [CVE-2026-58488](https://github.com/hedgedoc/hedgedoc/security/advisories/GHSA-2f9f-w8xq-276v) reports a rate-limiting bypass by abusing the CF-Connecting-IP header.

-
-### Important notices
-
- When using Cloudflare in front of HedgeDoc, you should set `rateLimitUsingCloudflare` in the config.json or `CMD_RATE_LIMIT_USING_CLOUDFLARE` as environment variable to `true`.
-
-### Enhancements
-
- Added a warning page when clicking external links
- Improve the config.json.example file, which is used by `bin/setup`
- Allow configuration of login / signup rate-limits
- Allow configuration of Cloudflare usage in regards of rate-limits
- Several improvements in the documentation at <https://docs.hedgedoc.org>
-
