+Table Compute
+-------------
+
+This tool is a Galaxy wrapper for the `Pandas Data Analysis Library <https://pandas.pydata.org/>`_ in Python,
+for manipulating and computing expressions upon tabular data and matrices. It can perform functions on the
+element, row, and column basis, as well as sub-select, duplicate, replace, and perform general and custom
+expressions on rows, columns, and elements.

     provide a more transparent workflow for complex operations.
 
 
+Many of the examples given below relate to common research use-cases such as filtering large matrices for
+specific values, counting unique instances of elements, conditionally manipulating the data, and replacing
+unwanted values. Full table operations such as normalisation can be easily performed by scaling the data via
+mean/median/min/max (and many other) metrics, and general expressions can even be computed across multiple
+tables.
