## HedgeDoc by cloudimg

HedgeDoc is the leading open source, self-hosted, real-time collaborative markdown editor - the community fork of HackMD. Multiple people edit the same note simultaneously in a split-pane editor with live rendered preview, presence cursors, diagrams, code highlighting, MathJax math, slide-deck presentation mode and image uploads. This Amazon Machine Image delivers HedgeDoc fully installed and configured as a system service, so your private note collaboration platform is running within minutes of launch. The release available is HedgeDoc 1.10.8.

## Application Stack

HedgeDoc runs on Node.js 20 LTS, installed from the official release tarball with the pre-built frontend, operated by an unprivileged service user under systemd. It listens on the loopback address only and is fronted by an nginx reverse proxy on port 80 with WebSocket upgrade support, which real-time collaboration requires. The SQLite database and image uploads live on a dedicated, independently resizable EBS volume separate from the operating system disk.

## Secure First Boot

Anonymous access and open self-registration are disabled. On first boot the instance generates a unique session secret and a unique admin account with a random password, seeded through HedgeDoc's own user management tooling and written to a root-only file. No shared or default credentials ship in the image and all build-time state is wiped before capture.

## Ready To Use

Browse to the instance on port 80, sign in with the generated admin credentials and start writing. Create additional users with the bundled user management CLI, or connect LDAP, SAML or OAuth2 identity providers through configuration. Publish read-only note views and present any note as a slide deck.
