 # What We Learnt ?
+
+## Metasploit Inrtoduction
+
+- Metasploit is a powerful tool that facilitates the exploitation process. The exploitation process comprises three main steps; *finding the exploit*, *customizing the exploit*, and *exploiting the vulnerable service*.
+
+- Metasploit provides many modules that you can use for each step of the exploitation process. Through this repo, we have seen the basic components of Metasploit and their respective use.
+
+- We also had used the `ms17_010_eternalblue` exploit to gain access to the target machine.
+
+## Metasploit : Exploitation
+
+- You should now have a better understanding of how Metasploit can help you identify potential vulnerabilities on target systems and exploit these vulnerabilities.
+
+- You have also seen how the database feature can help you with penetration testing engagements where you have multiple potential targets.
+
+- Finally, you should have gained some experience with msfvenom and the creation of stand-alone Meterpreter payloads. 
+
+- This is especially helpful in situations where you can upload a file to the target system or have the ability to download files to the target system.
+
+## Metasploit : Meterpreter
+
+- Meterpreter is a powerful tool that offers a lot of easy to use features during the post-exploitation phase.
+ 
+- We have seen how in-memory payloads can be used for post-exploitation.
