 A `jff` (just for fun) project that aims to create a
 model railroad assets manager that allows to:
 
-- Create a database of assets (model trains) and consits with their metadata
+- Create a database of assets (model trains) and consists with their metadata
 - Manage the database via a simple but rationale backoffice
 - Expose main data via an HTML interface to show how beautiful is your collection
   to the outside world
 - Act as a DCC++ EX REST API gateway to control assets remotely via DCC.
-  By anyone, if you'd like (really?).
