forEach(packages, async name => {
    const dir = path.join(__dirname, `../packages/${name}`);
    const pkg = require(path.join(dir, 'package.json'));

    const ast = await build([path.join(dir, 'index.js')], {});

    const dsc =
      ast.length && ast[0] && ast[0].description
        ? removeMd(
            remark()
              .stringify(ast[0].description)
              .split(/\n/)[1]
          )
        : pkg.dsc;

    const readme = await formats.md(ast, {});

    const pjson = JSON.stringify(
