Checklist

(Delete any that aren't relevant)

• Docs are successfully building - yarn install && yarn run build.
• For new internal links I used relative file paths (with .md extension) - e.g. ../../faq/faq-general.md - instead of introducing absolute file path, or relative/absolute URL.
• My changes follow the Casper docs style guidelines.
• All technical procedures have been tested (if you want help with this, mention it in Reviewers).
• If structural changes are introduced (not just content changes), cross-broswer testing has been completed.
