+# Custom Kalamar templates
+
+This directory is mounted into the Kalamar container at
+`/kalamar/templates/custom`. Kalamar renders a documentation page from here
+whenever it does not ship one of its own -- so a `doc/corpus.html.ep` becomes
+the corpus page -- and templates here can be referred to explicitly as
+`custom/...`. No configuration, no rebuilt image.
+
+To describe your own corpus, copy an example, drop the `.example` suffix and
+edit it:
+
+```bash
+cp custom/doc/corpus.html.ep.example custom/doc/corpus.html.ep
+$EDITOR custom/doc/corpus.html.ep
+docker compose restart kalamar
+```
+
+| file | replaces |
+|------|----------|
+| `doc/corpus.html.ep` | the corpus page, served at `/doc/corpus` |
+| `doc/citation.html.ep` | adds a references page at `/doc/citation` |
+| `partial/citation/corpus.html.ep` | the corpus part of the references page, passed to it as `corpus_citation` |
+
+The references page assembles three sections: your corpus references plus the
+shipped KorAP and annotation-tool references, which you normally keep as they
+are.
+
+Templates are [Mojolicious templates][mojo-templates]: mostly HTML, with
+`<%= ... %>` for embedded Perl. Files ending in `.html.md` are rendered as
+Markdown instead, which is handy for longer prose.
+
+For a translated page, put a copy under a language directory, e.g.
+`de/doc/corpus.html.ep` for German; visitors get it based on their browser
+language, with the unprefixed file as the default.
+
+Files that do not correspond to a Kalamar template -- such as the `.example`
+files here -- are simply ignored.
