Hi Silas.  

Here’s some content related to syntax

There’s also a great piece here by Chris from our org.

Thanks @dnehoda for providing some resources. @SilasRamsbottom Wanted to follow up to see if the information we provided helped answer your questions. If not, how else can we help you. Thanks!

Hi @matthewnichols ,
Thank you. 
It did help a lot. I have marked @dnehoda answer as solution as well.
The only challenge I’m facing now is the ability to practice it hands-on. Is there a community version available for practicing parser editing? I’ve already used up the initial $300 Google Cloud trial for another purpose 😇.

Thanks @SilasRamsbottom, there is not a community version available. 

Hi @matthewnichols ,
Thank you
