Getting Started > Web Enumeration

Hi there. So I’m stuck in this module. I really dont understand what the question is asking me to find.
the question is : Try running some of the web enumeration techniques you learned in this section on the server above and use the info you get to get the flag.
a flag?
I dont really understand. What I understand by a flag is the following:
for example, we have the command line: 'gobuster dir -u http://10.10.10.121/ -w /usr/share/dirb/wordlists/common.txt`
-u would be a flag and -w would be another flag.
With the resorces given by this module, I was able to find the admin panel but what I’m supposed to do with it ?
Someone please help me.
