 ## Why?
 
 Some node and python modules require a build system because they contain c++ binding. Once deployed, the compiled
-module may not be complatible with the Amazon Lambda execution environment.
+module may not be compatible with the Amazon Lambda execution environment.
 
 A common solution to this problem is to build the package on an EC2 instance using an Amazon Linux AMI and then to
 deploy it in Amazon Lambda. Building serverless applications, it is ironic to be obliged to use an EC2 server to deploy code.
