# Which Problems Are Solved
- Native iOS/Android passkeys need OS trust files on the ZITADEL domain;
without them, Associated Domains / App Links verification fails.
- Operators could not configure iOS Team ID + Bundle ID or Android
package name + SHA-256 fingerprints on OIDC apps.
- `/.well-known/apple-app-site-association` and
`/.well-known/assetlinks.json` were not served from application config.
# How the Problems Are Solved
- Add iOS/Android app-link fields on OIDC app create/update (Application
API v2 + Management), with validation.
- Persist and project those fields; query active app-link configs
instance-wide.
- Serve AASA (`webcredentials`) and Digital Asset Links
(`get_login_creds`) from well-known paths, with configurable
`Cache-Control` and fingerprint normalization at serve time.
- Console UI to edit the fields, with links to the well-known endpoints.
- Operator docs for configuration, endpoints, caching, and verification.
# Additional Changes
- Document on API fields that well-known responses may be HTTP-cached
and platform verifiers may delay propagation.
- Runtime config: `WellKnown.AppLinksCacheControlMaxAge` (default `5m`;
`0` → `no-store`).
# Additional Context
- Closes#12497
- Implemented and reviewed as stack:
- #12531 API contract
- #12532 storage wiring
- #12536 well-known endpoints
- #12537 console
- #12547 docs

## What
Shorten the `title` frontmatter on 20 docs pages so that the rendered
`<title>` tag stays within the 70-character SEO limit.
The root layout appends ` | ZITADEL Docs` (15 chars) to every page
title, meaning the raw frontmatter `title` must be ≤ 55 characters. A
site scan flagged all 20 pages for the "Title too long" warning (titles
ranged from 71 to 92 characters in the final rendered tag).
## Why
Search engines may truncate or ignore `<title>` tags longer than 70
characters, hurting click-through rates and keyword relevance in search
results.
## How
Each title was rewritten to:
- Fit within 55 characters (leaving room for ` | ZITADEL Docs`)
- Front-load the primary search keyword (product name, protocol, or
feature)
- Include "ZITADEL" where users realistically search for `{feature}
ZITADEL`
- Avoid generic filler words ("Configure", "Set up", "Support for")
All 20 files already have a `sidebar_label` field that preserves the
original descriptive title for sidebar navigation — no navigation
changes result from this PR.

## Todos for release
- [x] Configure Env in docs project on vercel
- [x] Configure Root Path in the docs project on vercel
- [ ] Remove old CSP https://github.com/zitadel/website/pull/1592
## What we did
This pull request migrates the project documentation from the old
`docs/` directory to the new `apps/docs/` directory, introduces a new
documentation system built with Next.js and Fumadocs, and updates all
relevant references, configuration files, and documentation to reflect
this change. It also adds new configuration and ignore files for the new
documentation app, updates CI and linting to exclude the new docs from
certain checks, and revises the contributing guidelines accordingly.
**Documentation System Migration and New Docs App**
* Migrated all documentation from `docs/` to `apps/docs/`, and updated
all references in `README.md`, `CONTRIBUTING.md`, and other files to
point to the new location.

* Added a new Next.js/Fumadocs-based documentation app under
`apps/docs/`, including core app files, layouts, routing, search API,
and a comprehensive `README.md` with development and contribution
instructions.

**Configuration and Tooling Updates**
* Updated `.github/workflows/codeql.yml`, `.golangci.yaml`, and
`.github/dependabot.yml` to properly handle the new docs app: excluded
`apps/docs` from certain checks, added npm dependency updates for the
docs app, and excluded generated content.

* Updated `.devcontainer/devcontainer.json` to use the latest Go 1.25.3
version for consistency.
**Licensing and Miscellaneous**
* Added `apps/docs/` to the list of licensed directories in
`LICENSING.md`.
These changes ensure the documentation is now maintained in a modern,
scalable system and all project tooling is updated to support the new
structure.
