+	<h1>Apex Legends Offset Dumper</h1>
+	<p>The <b>r5apex.exe</b> binary on disk is encrypted and must be dumped from memory first.</p>
+	<p>Simply run apexbot, if its offsets are not correct it'll dump the game for you instead. You'll find an <b>r5apex.bin</b> file in the current directory.</p>
+	<p>Drop the dumped executable in the file input below and the script on this page analyzes it for you returning offsets and other goodies.</p>
+	<p>This can take a while, do not stop this page! Give it a minute to crunch the binary...</p>
