Markers don't do anything, they are labels that you can put on your timeline to remember what happens when, they are just for your convenience.
When you want to create an animation you use keyframes.
Unfortunately it is almost a requirement that you have tried doing animations on your own machine before diving into the extra difficulties of using Blender with an online renderfarm.
Try creating and rendering a few animations on your own machine. You will find it a lot faster than having to wait a day for an admin to accept your session. As you start making more intricate models and more detailed animation maybe then you will find that the added power of the renderfarm starts to outweigh the initial wait.
You can learn more about Blender, keyframes and the timeline by browsing tutorials on Youtube
or with a lot more detail from the Blender Manual:
Once you have a cool animation you can create a video file with it:
And most importantly: Have fun!
