+# wie (Wikipedia Ingress Extractor) #
+This script extracts the first paragraph of any given Wikipedia article in any
+language. It's meant for terminal use, so one can read the ingress right from
+the console/terminal without starting a browser.
+
+## Usage ##
+Either make the script executable with 'chmod +x wie.php' and run it as such:
+
+    ./wie.php openbsd
+    ./wie.php --lang=sv minicall
+
+Or run it with 'php wie.php'. To display the help, type:
+
+    ./wie.php --help
+
+## Thanks ##
+Many thanks goes to flinga who came up with the idea for this script, please see
+the THANKS file for more information.
