### Import GPG Key

Source: https://github.com/blockchaincommons/qrcodegenerator/blob/master/Demo/QRCodeGeneratorDemo/README.md

Import a GPG key using the provided fingerprint. Ensure quotes are used for fingerprints with spaces.

```bash
gpg --recv-keys "<fingerprint>"
```

### Sign Contributor License Agreement

Source: https://github.com/blockchaincommons/qrcodegenerator/blob/master/CLA.md

Use this command to sign the CLA with your GPG key. Replace YOURGITHUBNAME and YOURGPGFINGERPRINT with your actual GitHub username and GPG fingerprint.

```bash
gpg --armor --clearsign --output ./CLA-signed/CLA.YOURGITHUBNAME.YOURGPGFINGERPRINT.md CLA.md
```

### Encode Text to QR Code and Print Emoji String

Source: https://github.com/blockchaincommons/qrcodegenerator/blob/master/README.md

This snippet demonstrates basic usage by encoding a simple string into a QR code with low error correction and then printing its emoji representation. Ensure the 'QRCode' type is imported.

```swift
let qr = try QRCode.encode(text: "Hello, world!", correctionLevel: .low)
print(qr.emojiString)
```

### Encode Chinese String with Optimal Segments

Source: https://github.com/blockchaincommons/qrcodegenerator/blob/master/README.md

Illustrates encoding the same Chinese string using `makeSegmentsOptimally`, which selects a sequence of segment types for more efficient encoding, resulting in fewer total bits.

```swift
Segment.makeSegmentsOptimally(text: "\u{9398}\u{8A69}\u{793E}\u{FF08}Wikipedia\uFF0C\u9810\u8072i/\u2070\u002f\u0077\u0069\u006b\u00f7\u0070\u0065\u0064\u0069\u0061\u002f\u0029\u662f\u4e00\u500b\u81ea\u7531\u5167\u5bb9\u3001\u516c\u958b\u7de8\u8f2f\u4e14\u591a\u8a9e\u8a00\u7684\u7db2\u8def\u767e\u79d1\u5168\u66f8\u5354\u4f5c\u8a08\u756b")
Segment(mode: kanji, characterCount: 5, data: <65 bits>)
Segment(mode: byte, characterCount: 9, data: <72 bits>)
Segment(mode: kanji, characterCount: 3, data: <39 bits>)
Segment(mode: byte, characterCount: 23, data: <184 bits>)
Segment(mode: kanji, characterCount: 6, data: <78 bits>)
Segment(mode: byte, characterCount: 3, data: <24 bits>)
Segment(mode: kanji, characterCount: 21, data: <273 bits>)
```

### Encode Chinese String with Single Byte Segment

Source: https://github.com/blockchaincommons/qrcodegenerator/blob/master/README.md

Demonstrates encoding a Chinese string using the `makeBytes` function, resulting in a single segment that requires a significant number of bits.

```swift
Segment.makeBytes(text: "\u{9398}\u{8A69}\u{793E}\u{FF08}Wikipedia\uFF0C\u9810\u8072i/\u2070\u002f\u0077\u0069\u006b\u00f7\u0070\u0065\u0064\u0069\u0061\u002f\u0029\u662f\u4e00\u500b\u81ea\u7531\u5167\u5bb9\u3001\u516c\u958b\u7de8\u8f2f\u4e14\u591a\u8a9e\u8a00\u7684\u7db2\u8def\u767e\u79d1\u5168\u66f8\u5354\u4f5c\u8a08\u756b")
Segment(mode: byte, characterCount: 140, data: <1120 bits>)
```
