  - `assets`: array of node module names to be copied to `static/assets` folder. **not stable feature.**
 
 
-## i18n
+## Additional information
 
-prepare i18n content under langauges folder (e.g., `en` or `zh-tw`) in `locales` folder, in `yaml` format. Filename maps to `namespace` concept in `i18next`.
-
-i18n data can be used in pug files via `i18n` function. e.g.,
-
-    div= i18n("my-key")
-
-will show `my-key` content defined in locale corresponding `default.yaml`:
-
-    my-key: 這是我的鍵
-
-
-To use a namespaced key, add `:` before key. For example:
-
-    div= i18n("new-ns:another-key")
-
-will access to `another-key` in `new-ns.yaml`. Be sure to add your namespace name in `ns` field of i18n option:
-
-    "i18n": { ...  "ns": ["default", "new-ns"] }
-
-additionally, use `intlbase` to wrap path with a i18n based relative path:
-
-    a(href=intlbase('/faq'))
-
-
-## Pug Include Path
-
-Use `@` to include files in modules:
-
-    include @/ldview/dist/ldview.pug
-
-Use `@static` to include files under `static` folder:
-
-    include @static/assets/sample.pug
+`template` now use `@plotdb/srcbuild` for source building, and thus there are some additional features available and documented in `@plotdb/ssrcbuild`. Please refer to [@plotdb/srcbuild](https://github.com/plotdb/srcbuild) for more information.
