+
+Frequently Asked Questions
+==========================
+
+Can KAT handle gzipped sequence files?
+--------------------------------------
+
+Yes, but only via named pipes.  For example, say we wanted to run ``kat hist`` using
+gzipped paired end dataset, we can use a named pipe to do this as follows::
+
+    mkfifo pe_dataset.fq && gunzip -c pe_dataset_?.fq.gz > pe_dataset.fq &
+    kat hist -o pe_dataset.hist pe_dataset.fq
+
+Where ``pe_dataset_?.fq.gz``, represents ``pe_dataset_1.fq.gz`` and ``pe_dataset_2.fq.gz``.
+
+For those unfamiliar with named pipes, the first line will create an empty file
+in your working directory called pe_dataset.fq and then specifies that anything 
+consuming from the named pipe will take data that has been gunzipped first.  To be
+clear this means you do not have to decompress the gzipped files to disk, this happens
+on the fly as consumed by KAT.
+
+Thanks to John Davey for suggesting this.
+
+
+Why is jellyfish bundled with KAT?
+----------------------------------
+
+We require a stable interface to the k-mer hash arrays produced by jellyfish hence,
+we are reliant on a particular version of jellyfish to guarantee that KAT works
+correctly.  Instead of potentially requiring the user to install multiple jellyfish instances
+on their machine, we bundle our own version, with all jellyfish binaries prefixed 
+with `kat_` in order to avoid any naming clashes with official jellyfish releases.
+
+
+I downloaded a release from github but it doesn't contain the configure script.  What gives?
+--------------------------------------------------------------------------------------------
+
+Github offers a feature which allows you to download source code bundles for all 
+releases.  However, these bundles do not contain the distributable form of KAT, i.e.
+they are not produced by calling ``make dist``.  Although they come from the same 
+place you can distinguish between the github bundles and the proper distributable form
+of KAT because it will have the name: ``kat-x.x.x.tar.gz``.

+=========
 
 KAT is a C++ program containing a number of subtools which can be used in
 isolation or as part of a pipeline.  Typing ``kat --help`` will show a

 The user loads a k-mer hash and then filters sequences (either in or out) depending 
 on whether those sequences contain the k-mer or not.  The user can also apply a 
 threshold requiring X% of k-mers to be in the sequence before filtering is applied.
+The user can also use this tool for filtering paired end reads, and for subsampling.
 
 Basic usage::
 
-    kat filter seq [options] <seq_file> (<k-mer_hash>)

 Applications:
 
- * Contamination extraction from read file or assembly file

+want to filter single end data or and assembly you can do this by simply dropping
+the ``--seq2`` option.
 
 BLASTing some of the sequences removed by the filtering might then identify the contaminant.
 
+You can also use this tool for subsampling the extracted data.  This can be useful
+for reducing expression of highly expressed reads.  To do this add the ``--frequency``
+option and set a threshold indicating how many of the reads to keep: 1.0 implies keep
