 ## Updating the website
 
-Our [website and docs](https://spacy.io) are implemented in
-[Jade/Pug](https://www.jade-lang.org), and built or served by
-[Harp](https://harpjs.com). Jade/Pug is an extensible templating language with a
-readable syntax, that compiles to HTML. Here's how to view the site locally:
-
-```bash
-sudo npm install --global harp
-git clone https://github.com/explosion/spaCy
-cd spaCy/website
-harp server
-```
+For instructions on how to build and run the [website](https://spacy.io) locally see **[Setup and installation](https://github.com/explosion/spaCy/blob/master/website/README.md#setup-and-installation-setup)** in the _website_ directory's README.
 
 The docs can always use another example or more detail, and they should always
 be up to date and not misleading. To quickly find the correct file to edit,
-simply click on the "Suggest edits" button at the bottom of a page. To keep
-long pages maintainable, and allow including content in several places without
-doubling it, sections often consist of partials. Partials and partial directories
-are prefixed by an underscore `_` so they're not compiled with the site. For
-example:
-
-```pug
-+section("tokenization")
-    +h(2, "tokenization") Tokenization
-    include _spacy-101/_tokenization
-```
-
-So if you're looking to edit the content of the tokenization section, you can
-find it in `_spacy-101/_tokenization.jade`. To make it easy to add content
-components, we use a [collection of custom mixins](_includes/_mixins.jade),
-like `+table`, `+list` or `+code`. For an overview of the available mixins and
-components, see the [styleguide](https://spacy.io/styleguide).
