+### Markdown plugins
+
+<base-alert>
+  markdown.basePlugins and markdown.plugins have been removed in favor of markdown.remarkPlugins and markdown.rehypePlugins.
+</base-alert>

+- Overriding plugins options can still be done but with prefixing by `remark` or `rehype`, for examps `externalLinks` becomes `remarkExternalLinks`.
+- You can now override all plugins or append a new plugin using `remarkPlugins` / `rehypePlugins`.
+- You can use local plugins using `~/plugins/remark-plugin.js`.
+- You can register and configure plugins on the same line like `['remark-plugin', { option: 1 }]`.
+
+Everything is documented in [this section](/configuration#markdown).

-See [defaults options](#defaults).
+Before diving into the individual attributes, please have a look [at the default settings](#defaults) of the module.
+
+### Merging defaults
+
+You can define every option either as function or as static value (primitives, objects, arrays, ...).
+if you use a function, the default value will be provided as the first argument.
+
+If you *don't* use a function to define you properties, the module will try to
+merge them with the default values. This can be handy for `markdown.remarkPlugins`, `markdown.rehypePlugins` and so on because
+the defaults are quite sensible. If you don't want to have the defaults include, just use a function.
