# Which Problems Are Solved

- Operators upgrading from ZITADEL v3 to v4 lacked a clear, docs-backed
upgrade path covering web keys (A-10017), Login V1 vs Login V2
expectations, and post-upgrade options.
- There was no standalone guide for adopting Login V2 after already
running on v4.
- Related ops/docs pages did not consistently point readers to the
upgrade and Login V2 adoption material.
- Kubernetes/Helm operators upgrading to a chart that ships ZITADEL v4
had no ops-page section linking the advisory, upgrade guide, optional
Login V2 deferral (`login.enabled: false`), and chart README upgrade
notes.

# How the Problems Are Solved

- Adds technical advisory **A-10017** documenting OIDC web key staging
requirements before upgrading to v4.
- Adds an **upgrade-v3-to-v4** guide with the recommended upgrade path
(Login V1 remains supported; Login V2 is optional at upgrade time).
- Adds a **v4-only adopt-login-v2** guide for teams adopting Login V2
later, with steps and caveats separate from the version upgrade.
- Adds an **Upgrading to ZITADEL v4** subsection under
`self-hosting/deploy/kubernetes/operations.mdx` that links to A-10017,
the upgrade guide, Adopt Login V2, notes `login.enabled: false` when not
adopting Login V2 yet, and points to the [Helm chart
README](https://github.com/zitadel/zitadel-charts/blob/main/charts/zitadel/README.md)
for chart-specific breaking changes.

# Additional Changes

- Registers new docs in the sidebar and wires Related / cross-links from
upgrade and ops pages so the advisory and guides are discoverable
together.
- Aligns language so upgrade vs. Login V2 adoption are clearly separated
concerns.
- Light cross-link updates on troubleshooting / updating-scaling /
login-client pages where related.

# Additional Context

- Related: A-10017 (web keys advisory)
- Docs paths introduced/updated:
  - `apps/docs/content/support/advisory/a10017.mdx`
  - `apps/docs/content/self-hosting/manage/upgrade-v3-to-v4.mdx`
  - `apps/docs/content/self-hosting/manage/adopt-login-v2.mdx`
- `apps/docs/content/self-hosting/deploy/kubernetes/operations.mdx` (new
"Upgrading to ZITADEL v4" section)
  - Sidebar and Related / cross-links

@zitadel/docs

Documentation for Zitadel, built with Fumadocs and Next.js.

Getting Started

Ensure you have followed the root quick start to set up dependencies.

Local Development

Ensure all dependencies are installed:

pnpm install

Start the development server:

pnpm nx run @zitadel/docs:dev

The site will be available at http://localhost:3000.

Scripts

Key scripts for documentation workflows:

Script Description
dev Starts the development server.
build Builds the production application.
fetch:remote-content Fetches remote tags and referenced content.
generate Runs all generation steps (fetch:remote-content, generate:proto-docs, generate:api-reference, generate:index-pages).
check:links Validates content integrity (broken links, missing frontmatter, schema errors).
check-types Validates typescript types.
test Runs all validation steps (check-types, check:links).
lint checks for code style and syntax errors (ESLint).
clean Cleans the build output and generated files.

Validation

  • Code Quality: Run pnpm nx run @zitadel/docs:lint to check for syntax and style issues in JS/TS/MDX files.
  • Content Integrity: Run pnpm nx run @zitadel/docs:check-links to validate content structure, including:
    • Broken internal links
    • Missing required front-matter (e.g., title)
    • Image references

Troubleshooting

Issue: Nx configuration not found or "nx" command not found

If you see errors like:

 NX   Cannot find configuration for task @zitadel/zitadel:@zitadel/docs:generate

Pass --verbose to see the stacktrace.

or

pnpm nx run @zitadel/docs:dev
 ERR_PNPM_RECURSIVE_EXEC_FIRST_FAIL  Command "nx" not found

Did you mean "pnpm nx"?

Root cause: Your dependency cache or node_modules is out of sync.

Solution: Run these commands from the repository root in order:

  1. Clear node_modules: rm -rf node_modules — removes the installed dependency folder
  2. Clear pnpm cache: pnpm cache delete — clears pnpm's internal package cache
  3. Reinstall dependencies: pnpm install — reinstalls all dependencies fresh
  4. Test the setup: pnpm nx run @zitadel/docs:generate — verifies everything works

This resolves 99% of setup-related issues.

Build Process

The docs build process automatically handles the following steps via generate:

  1. Downloads required protoc plugins.
  2. Generates gRPC documentation from proto files.
  3. Generates API documentation from OpenAPI specs.
  4. Generates index files for directory structures.

Style Guide

  • Variables: Use environment variables in code snippets where possible.
  • Embedded Content: Use _filename.mdx for content embedded in other pages (not indexed individually).
  • Code Embedding: Use the file property in code blocks to embed code from the repo.
  • Voice: Use active voice and sentence case for titles.

Refer to the Google Developer Style Guide for general guidelines.

Adding Content

All documentation content is located in the content directory. Note that the system strictly accepts only .mdx files.

To add a new page:

  1. Create a .mdx file in the appropriate subdirectory of content.
  2. Register the new page in the sidebar settings at lib/sidebar-data.ts to make it accessible in the navigation.

Pull Requests

Use docs(<scope>): <short summary> for PR titles. Pass quality checks before submitting:
