Implementation
A brand handoff checklist for designers and developers
A usable handoff gives the team the decisions and the working files. Before implementation, inspect the logo exports, fonts, design values, written guidance and real application examples as one package.

Open the files before assigning implementation
Check that the symbol and wordmark open correctly. Test a small use such as a favicon and a reversed use on a dark background. A file existing in a ZIP is not the same as a file working in the intended application.
Install the font in a test document and inspect the characters your product uses. Review the license and keep the original files with the chosen revision.
Trace one application back to the rules
Take a homepage or presentation example and identify the type roles, color meanings, logo treatment and tone. If the team cannot connect the example to the rules, record the missing decision before copying the visual.
Sigil’s Book includes application examples, tokens and brand.md. Use the examples to understand the rules, then implement them in your own components and content.
Keep one approved revision
Name the version the team should use. Keep source assets intact and make derivatives separately. A writer should not use old voice guidance while a developer installs the new colors.
Review accessibility, responsive behavior and font loading in the actual product. A polished brand book does not prove those implementation details are correct.
- Open the SVG logo and small-format assets.
- Test the fonts with real text and numbers.
- Inspect the tokens and their intended roles.
- Read the voice and imagery guidance.
- Rebuild one application from the rules.
- Share one approved revision with the team.
Common questions
- What should I send to my developer?
- Send the book, logo assets, font files, tokens and brand.md together, with the approved version clearly identified.
- Can I use the examples as templates?
- Use them to understand the system. Adapt the layout to your content and product rather than assuming every screen has the same job.
