# Contributing

Contributions that improve an existing entry or add a well-researched
self-hosted application are welcome.

## Opening an issue

Three forms cover what the catalog needs to hear: a catalog problem (wrong
data, a broken recipe, documentation, an asset), an application suggestion, and
an installation result.

An installation result is worth reporting when it went well, too. A recipe is
written and smoke-tested on a handful of machines, and a report from a
different server is the only evidence that its instructions hold anywhere else
— so "it worked, here is what I ran it on" is a useful issue. The application
page on [fossary.com](https://fossary.com) prefills the recipe context for you.

Security issues go through private vulnerability reporting instead, as
described in [SECURITY.md](SECURITY.md); do not put vulnerability details in a
public issue.

## Before opening a pull request

1. Read the [application requirements](docs/app-requirements.md),
   [recipe policy](docs/recipe-policy.md), and
   [editorial guide](docs/editorial-guide.md).
2. Use official documentation, repositories, releases, and container images as
   primary sources.
3. Never commit passwords, tokens, private keys, customer data, or other real
   credentials. Values in `.env.example` must be obvious placeholders.
4. Pin container images to a version. Do not use `latest`.
5. Write English source content first and keep every existing translation in
   sync.
6. Do not claim a smoke or restore result you did not perform.

## Local checks

Validate manifests with:

```bash
pipx run check-jsonschema==0.33.3 \
  --schemafile schemas/app-manifest.schema.json \
  apps/*/manifest.yaml
```

Validate a Compose recipe with its example environment:

```bash
docker compose \
  --env-file apps/<slug>/.env.example \
  --file apps/<slug>/compose.yaml \
  config --quiet
```

Run the recipe's smoke test only on an isolated machine where its containers,
volumes, and networks can be safely created and removed.

## Pull requests

Keep a pull request focused on one application or one catalog-wide contract
change. Explain the source of changed facts and list the checks you performed.
Screenshots must come from a real instance with realistic, non-sensitive data.

Catalog changes are integrated into the private Fossary application only after
the public checks and the full application integration suite pass.
