+Example of parsing RSS feeds with Lua. Before running the script install:
+- feedparser with `luarocks install feedparser`
+- luasocket with `luarocks install luasocket`
+
+```lua
+local http = require("socket.http")
+local feedparser = require("feedparser")
+
+local feed_url = "https://mitjafelicijan.com/feed.rss"
+
+local response, status, _ = http.request(feed_url)
+if status == 200 then
+  local parsed = feedparser.parse(response)
+
+  -- Print out feed details.
+  print("> Title   ", parsed.feed.title)
+  print("> Author  ", parsed.feed.author)
+  print("> ID      ", parsed.feed.id)
+  print("> Entries ", #parsed.entries)
+
+  for _, item in ipairs(parsed.entries) do
+    print("GUID    ", item.guid)
+    print("Title   ", item.title)
+    print("Link    ", item.link)
+    print("Summary ", item.summary)
+  end
+else
+  print("! Request failed. Status:", status)
+end
+```
