-### Specification files
-
-Test specification files are written in YAML, having file extension `.chk`. So, before you start writing any 
-specs, you should have a proper introduction to YAML, if you do not have already. Here is a fine
-[YAML cheatsheet](https://quickref.me/yaml) to grasp some knowledge. We are using this specific extension (`.chk`) 
-so these files do not make you confuse in typical project layout.
-
-> In the future evolution path of **chkware** we are going to introduce more and more specification 
-> options and specification types and versions.

-### Http specification
-

-format is how anyone express a Http request. Following is the full reference to write
