 **What this tool does**
 
-Estimates the drug-likeness of molecules and reports a score. Comes with three applicable varieties (QED\ :sub:`w,mo`\ , QED\ :sub:`w,max`\ , QED\ :sub:`w,u` ).
+Estimates the drug-likeness of molecules, based on eight commonly used molecular
+properties, and reports a score between 0 (all properties unfavourable) to 1 (all
+properties favourable). Two possible methods to weight the features are available
+(QED\ :sub:`w,mo`\ , QED\ :sub:`w,max`\), as well as an option to leave features
+unweighted (QED\ :sub:`w,u`).
+
+The eight properties used are: molecular weight (MW), octanol–water partition 
+coefficient (ALOGP), number of hydrogen bond donors (HBDs), number of hydrogen
+bond acceptors (HBAs), molecular polar surface area (PSA), number of rotatable
+bonds (ROTBs), number of aromatic rings (AROMs) and number of structural alerts
+(ALERTS).

+All invalid, blank and comment lines are skipped when performing computations. The
+number of skipped lines is displayed in the resulting history item. The method refers
+to a set of weights that can be applied to the features. These are derived in the
+`original paper`_ describing QED.
+
 
 - QED\ :sub:`w,max` using the set of weights that give maximal information content
 
 - QED\ :sub:`w,mo` using the mean weights of the optimal 1,000 weight combinations that give the highest information content
 
-- QED\ :sub:`w,u` with all weights as unity, hence unweighted.
+- QED\ :sub:`w,u` with all weights as unity i.e. unweighted.
