npmjs package page doesn't show readme

[josephfrazier]

At https://www.npmjs.com/package/estraverse, it says there is no readme:

This is because the published package does not include README.md:

$ tar tvf $(npm pack estraverse)
-rw-rw-rw-  0 0      0        1016 Mar 10  2016 package/package.json
-rw-rw-rw-  0 0      0       27642 Mar 10  2016 package/estraverse.js
-rw-rw-rw-  0 0      0        2790 Mar  7  2016 package/gulpfile.js
-rw-rw-rw-  0 0      0        1231 Mar  7  2016 package/LICENSE.BSD
-rw-rw-rw-  0 0      0         242 Mar  7  2016 package/.jshintrc
-rw-rw-rw-  0 0      0          29 Mar  7  2016 package/.babelrc
$

According to https://github.com/npm/registry/issues/120#issuecomment-276157329, old versions of npm didn't include README.md. If you upgrade your npm version, and publish a patch release of this module, the readme should appear on npmjs.com.
