-## Explanation
-Nmap is the only good portscanner for CTFs. RustScan knows this, and does not try to replace it.
-
-However, in a CTF, nmap scanning all 65k ports is **very** slow.
-
-RustScan **compliements** Nmap. RustScan scns all 65k ports with extreme speed and concurrency, and then it pipes those ports into Nmap.
-
-### Why not Massscan or copy and paste?
-It takes time to physically type out the port numbers into Nmap from masscan.

-Masscan probably wouldn't add this feature, as they are looking to be a competitor to Nmap.
-
-RustScan will execute Nmap the second it finds all the open ports. RustScan only wants to compliement Nmap, not beat it.

+# 🤔 What is this?
+If you are a competitive CTF player and often find yourself running masscan / a basic nmap scan before running a more comprehensive scan, this tool is for you.
+1. Find ports quickly using Rustscan. 
+2. Automatically runs `nmap -A -sV -p $ports -vvv` on those ports.
+3. Profit???
 
-TL;DR RustScan developers throw away their ego, and understand that no tool will ever come close to Nmap and instead chooses to compliement Nmap.
+Rustscans **only** job is to reduce the friction between finding open ports and inputting them into nmap.
