     * `txt` files can be released, but you should consider whether the output can be produced as a table, which is easier to review.
     * `json` files can be released, but as with tables, make sure that the attributes are easily understandable for reviewers. If the output can be represented as a table, you should consider converting it.
-    * `html` files can be released if you are producing a report style output, but please note the points below:
-        * `html` files are harder to review than other output types, so should be reserved for reports which require both contextual text and embedded outputs. Most commonly, [this will be a report](reports/intro.md) to be hosted on [OpenSAFELY Reports](https://reports.opensafely.org/). If you can produce your report locally, using individually released files, you should.

         * Make sure that any code blocks are not rendered in the rendered report if they are not needed. You can find [examples showing how to do this for Jupyter notebooks and R markdown files](reports/intro.md#producing-reports).
         * Each individual output within the report should be requested for release separately, with the contextual information outlined above.
         * `html` files should be stripped of any embedded javascript and styling. This is obfuscated when viewing a report via a web browser, but makes review of the raw file very difficult. Refer to our instructions [explaining how to strip the `html` files](reports/intro.md#producing-reports).
+        * When making a review request that includes `html` files, please include a link to the code you have used to produce the reports.
 
 If you would like to release other file types, please email <[email protected]>, stating why it is important that the file is released in a different format.
