+		config-metawrap sets database locations to $HOME by default during installation
 		numpy, openblas, and scipy versions updated for concoct 1.0

 		Fixed issue with program thinking READQC did not finish correctly
 	Assembly module:
 		Removed joint assembly feature. Now you can only assemble with metaSPAdes OR Megahit.
-		(megahit is defualt due to its speed)
+		(megahit is default due to its speed)
 		Changed minimum contig length from 500bp to 1000bp
 	Binning module:
 		This module is now split into four parts for modularity:
