+# web_crawler
+This simple web crawler fetches news from the homepage of HN (https://news.ycombinator.com/).
+
+# Compile and Run
+
+Use this to generate an executable, and then launch the web crawler:
+```bash
+v web_crawler.v
+./web_crawler
+```
+
+And this to compile and launch the web crawler directly:
+```bash
+v run web_crawler.v
+```
+
+This project shows how to use http.fetch() to get http.Response, 
+and then html.parse() to parse the returned html.
+
+It's easy, isn't it?
