Use it with

npm install --save markdown-it-samp

import MarkdownIt from 'markdown-it'
import MarkdownItSamp from 'markdown-it-samp'

const md = new MarkdownIt()
md.use(MarkdownItSamp)

console.log(md.render('´´´\nresult\n´´´\n')) // <pre><samp>result</samp></pre>

I'll provide a better readme, tests, etc in future days.
