While reading through the book I have noticed a few grammatical issues in the English version and I want to help fix them.
I will create a pull request when I am done.

Are the capitalisations on the mod concepts intentional?
Some link to the concept page but not all do.
Should these all link to the concept page?

If I am reading the files correctly putting $(l:bigreactors:JSON_PATH)TEXT_GOES_HERE$(/l) makes it add the link.

How do you maintain the 1.12 and 1.16 versions? (if you are still developing both versions)
Will the changes I make apply to both or do I need to change something else for the 1.12 version?
