Here is where you will learn your options for spending development points.  There will never be enough points to build your character as you wish so you must prioritize.  Choose wisely!

You will have noted from the bottom of the Stats page that your development points are determined by the average of your Agility, Constitution, Memory, Reasoning, and Self-Discipline temporary stats.  This is the total from which you must build your character at level 1 and at each level following.  There are a number of places you can spend your Development Points (referred to as DP) which include the following: Training Packages (TP), stat gains (past 1st level, see Level Up for details), skill categories, and skills themselves.

Note: you may not save DP from one level to the next
Note: TP are usually available only at level 1.

See the Master Skill Summary Table on Character Law pages 114-115 regarding any questions concerning which skill belongs in which category as well as which type each category is (Standard/combined/special/etc.)

There is a cost associated with each of these as well as a predetermined number of ranks you can increase at each level up.  See your respective Profession page as well as for those details.
