-## CSP header
-
-The GitLab docs site uses a [Content Security Policy (CSP) header](https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP)
-as an added layer of security that helps to detect and mitigate certain types of
-attacks, including Cross Site Scripting (XSS) and data injection attacks.
-Although it is a static site, and the potential for injection of scripts is very
-low, there are customer concerns around not having this header applied.
-
-It's enabled by default on <https://docs.gitlab.com>, but if you want to build the
-site on your own and disable the inclusion of the CSP header, you can do so with
-the `DISABLE_CSP` environment variable:
-
-```shell
-DISABLE_CSP=1 bundle exec nanoc compile
-```
-
-### Adding or updating domains in the CSP header
-
-The CSP header and the allowed domains can be found in the [`csp.html`](/layouts/csp.html)
-layout. Every time a new font or Javascript file is added, or maybe updated in
-case of a versioned file, you need to update the `csp.html` layout, otherwise
-it can cause the site to misbehave and be broken.
-
-### No inline scripts allowed
-
-To avoid allowing `'unsafe-line'` in the CSP, we cannot use any inline scripts.
-For example, this is prohibited:
-
-```html
-<script>
-$(function () {
-  $('[data-toggle="popover"]').popover();
-  $('.popover-dismiss').popover({
-    trigger: 'focus'
-  })
-})
-</script>
-```
-
-Instead, this should be extracted to its own files in the
-[`/content/assets/javascripts/`](/content/assets/javascripts/) directory,
-and then be included in the HTML file that you want. The example above lives
-under `/content/assets/javascripts/toggle_popover.js`, and you would call
-it with:
-
-```html
-<script src="<%= @items['/assets/javascripts/toggle_popover.*'].path %>"></script>
-```
-
-### Testing the CSP header for conformity
-
-To test that the CSP header works as expected, you can visit
-<https://cspvalidator.org/> and paste the URL that you want tested.
