We should have at least three files: 'Widget.svelte', 'rollup.config.js' and 'package.json':

1. Our widget Widget.svelte:

<script>
	export let name;
</script>

<h1>Hello {name}!</h1>

Clean Install High Sierra on APFS-formatted main HD

Installation Steps

1. From 10.11 or 10.12 systems, format an external hard drive with at least 500gb with "Mac Os Extended Journaled".
2. Download High Sierra Beta and install it in the external hard drive.
3. When the system reboots and finishes installation, it will boot from the external HD. Go to Preferences and change Startup Disk to be main HD.
4. Reboot and press Option key when the computer makes a beep and select external HD to boot from it.
5. Once booted again into external HD, format main HD to be APFS.

For troubleshooting, two things to first try:

run `git config --global gpg.program gpg2`, to make sure git uses gpg2 and not gpg
run `echo "test" | gpg2 --clearsign`, to make sure gpg2 itself is working
If that all looks all right, one next thing to try:

run `brew install pinentry` to ensure you have a good tool installed for passphrase entry
If after that install and you re-try git commit and still get the "failed to sign the data" error:

run `gpgconf --kill gpg-agent` to kill any running agent that might be hung
