-<p>This 2 weeks were not very productive I think. I published libweb. I think it already can
-support the most basic web 1.0 pages, because it has support of headers (h1, h2, &hellip;)
-and paragraphs tags (p). This week I tryed to implement title tag but had troubles with it,
-will publish it when it will be done&hellip;</p>
