 FlowUtils API
 ===================================
 
+FlowUtils includes 2 modules: :code:`compensate` and :code:`transforms`
+containing functions for compensation and various transforms, respectively.
+
 compensate Module
 -----------------
 
+The :code:`compensate` module includes functions for parsing the spillover
+keyword value from the metadata within an FCS file, creating a compensation
+from CSV or NumPy input types, and for applying a compensation matrix to
+FCS event data (as a NumPy array).

 transforms Module
 -----------------
 
+The :code:`transforms` module includes functions for applying various
+transformations (and their inverse) to FCS event data that are commonly used within the
+flow cytometry community. These include:
+
+- Logarithmic
+- Inverse hyperbolic sine (asinh)
+- Logicle
+- Hyperlog
