Migration from Valine

Since Waline completely reuses Valine's data structure in storage, migrating from Valine to Waline is very simple.

1. Deploy backend according to Vercel Deploy in Get Started section. LEAN_ID and LEAN_KEY should be the same as those applied for when using Valine before. Don't forget to set LEAN_MASTER_KEY for Waline.

2. Modify frontend scripts according to HTML in Get Started section. Please remind we should remove old configuration appId and appKey from Valine, and add serverURL option.

   - <script src='//unpkg.com/valine/dist/Valine.min.js'></script>
   + <script src='//unpkg.com/@waline/client@v2/dist/waline.js'></script>
   + <link href='//unpkg.com/@waline/client@v2/dist/waline.css' rel='stylesheet' />
   
     <script>
   -  new Valine({
   +  Waline.init({
       el: '#vcomments',
   -   appId: 'Your appId',
   -   appKey: 'Your appKey'
   +   serverURL: 'YOUR SERVER URL'
     });
     </script>
