What Ledger is, local-first vs the cloud, your first run, and the seeded sample knowledge base.
Doc tree & spaces, search, the editor & live preview, wiki-links & backlinks, the Links/graph view, version history + diff + restore, templates, tags, governance, roles & permissions, published portals, import, export, and the no-secrets posture.
What signing in adds, entitlements, the shared org vault, and evidence emission to Sightline.
Connect a real vault folder, the two-way sync model (push/pull/conflict/delete), auto-sync, and browser support with the Firefox/Safari fallback.
Install it inside Obsidian, the access token, Verify, Push/Pull org vault, Mark reviewed, governance report, publish evidence, settings, and token security.
Supported providers, where the key lives, the three flows (draft / summarize / ask), and the secret scrubber.
Run the free engine on your own infrastructure, deploy as a subpath, and what's included for $0.
No secrets stored, zero-network when signed out, where your data lives, and the save-time secret scanner.
Open Source, hosted Free, Pro, Teams, read-only portal users, the Discovery add-on, and how the cost compares.
Real error states and answers: "sync did nothing", permission denied, sign-in failed, a flagged secret, portal won't open, browser support, data loss/recovery, and exporting & leaving.
Short, task-focused recipes that link straight to the steps you need.

Ledger helps you write, govern, and share documentation. It is not a substitute for your own backups, your password manager, or your compliance controls. See Security & privacy.
