# Update existing documentation
After you have added a new set icon, update the codebase and generate the new `keyrune.css` file, you need to update the documentation to reflect the changes.
## Steps
1. Run this command
```bash
npm run build
```
This will copy fonts and css files to the `docs` folder.
2. Add the new icon usage inside the `cheatsheet.html`.
```diff
+
```
Replace `fdn` with the short code of the new icon.
3. Add the new icon usage inside the `icons.html`.
```diff
+
+ Foundation (fdn)
+
```
Replace `fdn` with the short code of the new icon.
> A data attribute with the version is present, but i don't know how it's working. If you have info about it, please add it in this doc here. 🙏
You can open each html file in your browser to see the changes. Or use tools like `Live Server` in Visual Studio Code.
Normally you can see the changes in the `./cheatsheet.html` and `./icons.html` .
