Add section explaining how to read the CSD and what to be looking for. Add example CSD pictures for reference.

When looking at the CSD, we are trying to see what material is peaking in the oven. The high peaks, about three, should be 16O. The rest of the most prominent peaks should be whatever material the oven currently has. Toggle the main ion species so you can find the corresponding peaks. Find the one that has the highest peak value in current; this is what we are peaked on.
