+Csvtk - Freq Help
+-----------------
+
+Info
+####
+Find the frequency of the data based on the selected column(s).
+
+If one column is selected, the frequency will be the number of times each value is found in the column. These can further be sorted if so desired.
+
+Examples can be found in the usage section below!
+
+.. class:: warningmark
+
+    Single quotes are not allowed in text inputs!

+
+
+Usage
+#####
+
+To run csvtk-freq, all you need is a valid (as defined above) CSV or TSV and the column(s) that you want the frequency of.
+
+**Ex. of frequency with one column:**
+
++------------+-----------+
+| Blood Type | Frequency |
++============+===========+
+| A          | 31        |
++------------+-----------+
+| B          | 103       |
++------------+-----------+
+| etc.       | etc.      |
++------------+-----------+
+
+----
+
+**Ex. of frequency with more than one column for frequency:**
+
++---------+------------+-----------+
+| Name    | Blood Type | Frequency |
++=========+============+===========+
+| Bob     | A          | 4         |
++---------+------------+-----------+
+| Jacob   | B          | 5         |
++---------+------------+-----------+
+| Matthew | O          | 12        |
++---------+------------+-----------+
+| Darian  | AB         | 1         |
++---------+------------+-----------+
+
+With multiple columns, you end up getting the frequency of how many times the values from each column
+are found together. In this example from an input dataset of names and bloodtypes, we can find the frequency that
+each name in our database is a certain bloodtype. 
+
+Here, we can note that there are 4 people named bob with blood type A.
