+# Signing Configuration
+
+## Setup
+
+1. **Export your GPG secret key:**
+   ```bash
+   gpg --export-secret-keys --armor YOUR_KEY_ID > /path/to/secring.gpg
+   ```
+
+2. **Get your Sonatype user tokens:**
+   - Go to https://central.sonatype.com/usertoken
+   - Click "Generate User Token"
+   - Save the username and password
+
+3. **Create `export_signing.sh`:**
+   ```bash
+   #!/bin/bash
+
+   # Configuration
+   SIGNING_KEY_FILE="/path/to/secring.gpg"
+   SIGNING_KEY_ID="8E72E6C6"  # Last 8 chars of your GPG key ID
+   SIGNING_KEY_PASSWORD="your_gpg_passphrase"
+
+   # Maven Central credentials (Sonatype user tokens)
+   export ORG_GRADLE_PROJECT_mavenCentralUsername="your_token_username"
+   export ORG_GRADLE_PROJECT_mavenCentralPassword="your_token_password"
+
+   # GPG signing configuration
+   export ORG_GRADLE_PROJECT_signingInMemoryKey=$(cat "$SIGNING_KEY_FILE")
+   export ORG_GRADLE_PROJECT_signingInMemoryKeyId="$SIGNING_KEY_ID"
+   export ORG_GRADLE_PROJECT_signingInMemoryKeyPassword="$SIGNING_KEY_PASSWORD"
+
+   echo "Signing environment variables exported successfully"
+   ```
+
+4. **Make it executable:**
+   ```bash
+   chmod +x export_signing.sh
+   ```
+
+## Usage
+
+Run the upload script:
+```bash
+./.buildscript/upload_archives.sh
+```
+
+The script automatically sources `export_signing.sh` to set up signing.
