+### Custom inline styles and block styles
+
+The default supported inline styles:
+
+```js
+{
+  Strong: {
+    type: 'BOLD',
+    symbol: '__'
+  },
+  Emphasis: {
+    type: 'ITALIC',
+    symbol: '*'
+  }
+}
+```
+
+The default supported block styles:
+
+```js
+{
+  List: 'unordered-list-item',
+  Header1: 'header-one',
+  Header2: 'header-two',
+  Header3: 'header-three',
+  Header4: 'header-four',
+  Header5: 'header-five',
+  Header6: 'header-six',
+  CodeBlock: 'code-block',
+  BlockQuote: 'blockquote'
+}
+```
+
+Inline styles and block styles can be extended or overridden by passing a custom styles object as a second optional argument to `mdToDraftjs`, e.g.
+
+```js
+const markdown = "Some `markdown` with ~~deleted~~ text";
+
+const myCustomStyles = {
+  inlineStyles: {
+    Delete: {
+      type: "STRIKETHROUGH",
+      symbol: "~~",
+    },
+    Code: {
+      type: "CODE",
+      symbol: "`",
+    },
+  },
+  blockStyles: {
+    CustomBlock: "custom-block",
+  },
+};
+
+const content = mdToDraftjs(markdown, myCustomStyles);
+```
+
+The keys to the `inlineStyles` object should be valid [AST node types](https://github.com/textlint/textlint/blob/master/docs/txtnode.md).
