Its not too hard, so you're in luck!

If you want to have a dynamic subject line:

1. At the top of your email, make an AMPscript block, like %%[ ]%%. Declare a variable, like VAR @subject

2. Within that block, do all your logic that will set this dynamic variable.

3. Make the subject of your email %%=v(@subject)=%% . This will populate at send time.

If you want to store your subject lines in a Data Extension and retrieve them dynamically:

4. Your Sendable Data Extension should contain the Segment field:

5. Create your Data Extension to lookup the Subject Line from, it should contain Segment as the key. I named my DE "Subjectline Table":
   

6. In your email content, set your @Subject variable using the LookUp() function.

   %%[ 
   Set @Subject = LookUp("Subjectline Table","SubjectLine","Segment",Segment)
   ]%%
   

7. In your Email Properties, set the subject line to be %%=v(@Subject)=%%

Hope this helps, good luck!
