+if u want to add more ,like php. just edit `src/render.js` ,and then add a language import.

+```javacript
+import marked from 'marked'
+import Prism from 'prismjs'
+//this line ↓
+import prism_php from 'prismjs/components/prism-php'
+// or
+import prism_ruby from 'prismjs/components/prism-ruby'
+// and so on...
