+## Tests
+
+For normative changes, a corresponding
+[web-platform-tests](https://github.com/web-platform-tests/wpt) PR should be included. Typically,
+both PRs will be merged at the same time. Note that a test change that contradicts the spec should
+not be merged before the corresponding spec change. If testing is not practical, please explain why
+and if appropriate [file an issue](https://github.com/web-platform-tests/wpt/issues/new) to follow
+up later. Add the `type:untestable` or `type:missing-coverage` label as appropriate.
+
+## Style guide to contributors
+
+- the spec uses [ReSpec](https://github.com/w3c/respec/wiki)
+- the spec is tidied using [HTML5 Tidy](https://github.com/w3c/tidy-html5). For
+  instructions on running HTML5 tidy, see below.
+- put comments in front of sections, for better readability with
+  syntax coloring editors
+
+## Running HTML5 Tidy
+
+Please make sure you have HTML5 tidy installed, instead of
+the the one that ships with \*nix systems. You can confirm this by running:
+
+```bash
+tidy --version
+#HTML Tidy for [some OS] version...
+```
+
+Once you have confirmed (make sure you have committed your changes before
+running tidy, as the changes are destructive ... in a good way:)):
+
+```bash
+tidy -config tidyconf.txt -o index.html index.html
+```
