+CUSTOMIZING THE BEHAVIOR OF FOLLOWING URL LINKS
+
+By default, when you use `:ObsidianFollowLink` on a link to an external URL it 
+will be ignored. However, you can customize this behavior by setting the 
+configuration option `follow_url_func` to a function that takes the URL as its 
+first argument.
+
+For example, you might want to open it in the browser. Here's an example of 
+how you could implement this:
+
+>lua
+    require("obsidian").setup({
+      follow_url_func = function(url)
+        -- Open the URL in the default web browser.
+        vim.fn.jobstart({"xdg-open", url})
+      end,
+    })
+
+In this example, we use `vim.fn.jobstart` function to open the URL in the default 
+web browser.
