It looks good to me. I have the following niggles:

1. "Comment out" is very specific. I think it might be good enough to say "Unnecessary if none of your source code is Kotlin"
2. Consistent code formatting would be nice. We have

kotlinOptions { jvmTarget = '1.8' }

and...

compileOptions
{

and...

    maven {
        url "https://mobile.maven.couchbase.com/maven2/dev/"
    }

I suggest, instead:

kotlinOptions { jvmTarget = '1.8' }

compileOptions {
...

maven { url "https://mobile.maven.couchbase.com/maven2/dev/" }

3. Finally, it would be nice to be consistent about the way sections are displayed. The point describing what gets included in the android section does not show the android section, and is not indented so that it is clear that it goes into the section. The next two points, Update Carthage instruction #2 & encryption specification #3 do show the including section but do not allude to the fact that the sections will, almost certainly, contain other things, needed by the application program. Also, note, FWIW, that there is nothing about CBLite that requires either google() or jcenter().

These are just niggles. Adopt them or not as you see fit.
