The source code for GoDoc is available on GitHub.
GoDoc displays documentation for GOOS=linux unless otherwise noted at the bottom of the documentation page.
It's important to write a good summary of the package in the first sentence of the package comment. GoDoc indexes the first sentence and displays the first sentence in package lists.
To add a package to GoDoc, search for the package by import path. If GoDoc does not already have the documentation for the package, then GoDoc will fetch the source from the version control system on the fly and add the documentation.
GoDoc checks for package updates once per day. You can force GoDoc to update the documentation immediately by clicking the refresh link at the bottom of the package documentation page.
GoDoc crawls package imports and child directories to find new packages.

$ curl -H 'Accept: text/plain' http://godoc.org/math
