+# Echo documentation examples
+
+These complete programs are intended to be the source for code displayed on the
+Echo website. The site should embed the files directly instead of maintaining
+copied snippets.
+They compile against the Echo checkout that contains them.
+
+Run `go test ./...` from this directory. The nested module keeps example-only
+dependencies and files out of the published Echo library module. The local
+`replace` directive is intentional: it makes an Echo pull request test its own
+source rather than a previously released version.
+
+To try the Static example, run `go run .` from `static/`, then open
+`http://localhost:1323/`. Its `public/index.html` is the file served at `/`.
+
+`go run ./cmd/config-fields -root ../.. -revision <commit>` emits deterministic
+JSON for exported middleware `*Config` fields, types, deprecation markers, and
+source line numbers. It is source data for the website, not a published page.
+It does not generate runtime defaults, behavior claims, or security guidance.
+
+The Echo documentation workflow also checks out `echox`, compiles its cookbook
+against the proposed Echo checkout using a temporary Go workspace, and builds
+the current site. A future `echox` change will consume the JSON and these exact
+example files before the reference-drift check becomes a required gate.
+
+This is the first source-owned slice: Request Logger and Static. Behavior notes,
+security guidance, and translated explanations remain authored in `echox`.

+# API reference tool trial
+
+The first trial used `gomarkdoc` v1.1.0 against this Echo checkout's
+`middleware` package, which includes CORS, Request Logger, and Static, and
+against the external `github.com/labstack/echo-jwt/v5` package from the current
+`echox` module. The package output was 2,422 lines for core middleware and 389
+lines for JWT. `gomarkdoc --check --output ...` successfully detected that the
+unmodified generated core file matched its source. The output included
+`EnablePathUnescaping` and excluded the removed `RequestLoggerConfig.LogError`.
+
+`--embed` supports marked regions within authored Markdown. A check against an
+unmarked, fully generated file failed because embed mode would append a second
+generated block. This confirms that an existing page must add embed markers
+before using that mode. Templates can change generated Markdown, but this
+package-wide output is too broad for individual middleware pages and is not a
+machine-readable field manifest. Those two requirements motivate the small
+`config-fields` extractor in this module. It extracts only fields, types,
+deprecation markers, and source positions; it does not infer defaults or
+rewrite authored pages.
+
+The site integration will separately evaluate a targeted `gomarkdoc` template
+and marked embedding on a real page before choosing how to render reference
+sections. This trial does not justify generating behavior explanations.
