Hello @beatyt

You have to update the templating.md file and you new template engine:

https://github.com/tsedio/tsed/blob/production/docs/docs/templating.md

You can also add unit test to cover the code. Take as example this test:

https://github.com/tsedio/tsed/blob/200c84c2303ac7041fa3245cbc793bfe73207f4a/packages/engines/src/components/PugEngine.spec.ts

See you

Hey @beatyt
I implemented test and fixed the Eta engine instantiation to be compliant with Ts.ED Configuration :)

It should be ok now :)
