-### Compatablity
+### Compatibility
 
 While snakemake and Acanthophis are cross-platform, most of the underlying tools are only packaged for and/or only operate on  Linux `x68_64`. Therefore, I only support users on Linux systems. In theory, everything *should* run on OSX or WSL, but the vast majority of users will want to utilise a high performance linux workstation (at least, probably more likely a cluster).
