 # ShellSpider
 A web-server in shell script
+
+Why?
+====
+Because I can.
+
+Requirements
+============
+- an up-to-date version of bash
+- socat (for networking)
+- python (for url-encoding)
+- some other basic tools, like sed, grep, awk, getopt
+
+Usage
+=====
+
+```
+./server.sh --port=[PORT]
+```
+
+For other options start the script without the port-option.
+
+Why again?
+==========
+I did this just for fun. I wanted to reach the limits of shell scripts. Turned out: Building a fully functional webserver is possible.
