This accessibility statement applies to

This website is run by the University of Edinburgh as the lead partner for the Software Sustainability Institute. We want as many people as possible to be able to use this application. For example, that means you should be able to:

  • change colours, contrast levels and fonts, using your browser’s settings
  • zoom in up to 300% without the text spilling off the screen
  • navigate most of the website using just a keyboard
  • navigate most of the website using speech recognition software
  • access our A to Z glossary of common abbreviations and acronyms used across our website, although these are always explained when first mentioned.

We’ve also made the website text as simple as possible to understand. However, some of our content is technical, and we use technical terms where there is no easier wording we could use without changing what the text means.

Customising the website

AbilityNet has advice on making your device easier to use if you have a disability. This is an external site with suggestions to make your computer more accessible:

With a few simple steps you can customise the appearance of our website using your browser settings to make it easier to read and navigate:

Disproportionate burden

We are not currently claiming that any accessibility problems would be a disproportionate burden to fix.

Content that’s not within the scope of the accessibility regulations


Many of our older PDFs are not fully accessible and they may not be easy to view using a screen reader. For example:

Help! My developer is running away, although we host an alternative version on the website.

The accessibility regulations do not require us to fix PDFs or other documents published before 23 September 2018 if they’re not essential to providing our services. Any new PDFs we publish will meet accessibility standards.

Other websites hosting our resources

Some of our resources are published on external platforms such as Zenodo, Github, and ReadTheDocs. We use Eventbrite to manage our events, though all events information can be found on this website. Finally, we use Spreadshirt for the sale of our branded t-shirts.

What we’re doing to improve accessibility

We will continue to address the accessibility issues highlighted, alongside working to deliver a solution or suitable workaround. Unless specified otherwise, a complete solution or significant improvement will be in place for those items within our control by March 2022 .

While we are in the process of resolving these accessibility issues, or where we are unable, we will ensure reasonable adjustments are in place to make sure no user is disadvantaged. As changes are made, we will continue to review accessibility and retest the accessibility of this website.

Preparation of this accessibility statement

This statement was prepared on 5th July 2019. It was last reviewed on 2nd September 2020.

  • Warning of links opening in a new tab or window
  • Information conveyed in colour or sound only
  • Flashing or scrolling text
  • Operability if JavaScript is disabled
  • Tooltips and text alternatives for any non-text content
  • Time limits
