Catalog edits in YAML or Go. Use for any task that adds an App, changes an App's image, port, Compose, env, notes or StandaloneGuide (even a one-line image bump), changes a Recipe, or hides or unhides an App. Each of these changes generated site and DCM data and the generated e2e inventory. DCM-only Containers go to add-container; Homarr wiring goes to docs/agents/homarr-integrations.md.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Edit the Catalog Read `CONTEXT.md` for App, Recipe and Catalog, and `docs/agents/generated-data.md` for what is derived from what. For a new App, copy the shape of the last one: `git show --stat ca78641b` (Cleanuparr). Pick the branch, then run its steps in order: - **New App**: steps 1 to 8. - **Change an App**: steps 1, 2, 6 and 8, plus 5 when its repository or icon changes. If `internal/catalog/specs/<id>.yaml` exists, edit that file. Otherwise edit the App's package under `internal/apps/`; its directory is the id without hyphens or a shorter name (`paperless-ngx` lives in `paperlessngx`), so find it with `grep -rl 'ID: "<id>"' internal/apps`. - **Change a Recipe**: edit `defaultRecipes` in `internal/catalog/recipes.go`, then steps 6, 7 and 8. - **Hide or unhide an App**: edit `unavailable` in `internal/catalog/catalog.go` with the reason and the issue that tracks the way back, then steps 6, 7 and 8. ## 1. Resolve upstream facts Take the image, tag, ports, volumes and env from the project's own docs or registry page, not from memory or an aggregator. **Done:** each fact has a source URL you can put in the PR body. ## 2.

How to install
mdr add ajnart/self-host/edit-catalog@sha256:d9ee0963cf2afd5bThe line at the top of this page pins the label git:20261104.758c8e5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
