+# paper-radio-button
+
+`paper-radio-button` is a button that can be either checked or unchecked.
+User can tap the radio button to check it.  But it cannot be unchecked by
+tapping once checked.
+
+Use `paper-radio-group` to group a set of radio buttons. When radio buttons
+are inside a radio group, only one radio button in the group can be checked.
+
+Example:
+
+```html
+<paper-radio-button></paper-radio-button>
+```
+Styling a radio button:
+
+```html
+<style is="custom-style">
+  :root {
+    /* Unchecked state colors. */
+    --paper-radio-button-unchecked-color: #5a5a5a;
+    --paper-radio-button-unchecked-ink-color: #5a5a5a;
+
+    /* Checked state colors. */
+    --paper-radio-button-checked-color: #009688;
+    --paper-radio-button-checked-ink-color: #0f9d58;
+  }
+</style>
+```
