 Filters use the [HTML::Pipeline](https://github.com/jch/html-pipeline) library. They take an HTML string or [Nokogiri](http://nokogiri.org/) node as input, optionally perform modifications and/or extract information from it, and then outputs the result. Together they form a pipeline where each filter hands its output to the next filter's input. Every documentation page passes through this pipeline before being copied on the local filesystem.

+Once docs have been uploaded via `thor docs:upload` (if applicable), you can push to the DevDocs main branch (or merge the PR containing the updates). If the Travis build succeeds, the Heroku application will be deployed automatically.
 
 - If you're deploying documentation updates, verify that the documentations work properly once the deploy is done. Keep in mind that you'll need to wait a few seconds for the service worker to finish caching the new assets. You should see a "DevDocs has been updated" notification appear when the caching is done, after which you need to refresh the page to see the changes.
 - If you're deploying frontend changes, monitor [Sentry](https://sentry.io/devdocs/devdocs-js/) for new JS errors once the deploy is done.
