"forebearers" is not actually a word

"forebears" means ancestors. "forebearers" is not a word according to
any serious dictionary (Merriam-Webster does not count).

copy edit: "forebearers" is not actually a word
clarified example

this page used to say

`<li>{{#linkTo posts.post post}}{{post.title}}{{/linkTo}}</li>`

now it says

`<li>{{#linkTo photos.edit photo}}{{photo.title}}{{/linkTo}}</li>`

I first read this page in the late afternoon after many hours of work. I
found `posts.post post}}{{post.title` confusing, given that `post` can
be either a noun or a verb in the example (and given that it can also be
an HTTP verb).

clarified example
added missing backticks for legibility
named outlets, and rewritten warning message stuff

named outlets are referred to in the original, but not explained, so I
had to go on Stack Overflow to find out what they were. this version of
the doc gives a brief overview of named outlets. (in an ideal world I'd
also have an update for the handlebars template section. maybe one day.)

I rewrote the warning message stuff because I found it difficult to
understand. it also kind of just appeared out of nowhere in the middle
of a structure which leads you through the basics of template rendering,
so I moved it down to its own section.
