### Installation

Download both tgz files and install them together:

\`\`\`bash
npm install ./salesforce-b2c-tooling-sdk-${version}.tgz \\
            ./salesforce-b2c-cli-${version}.tgz
\`\`\`

Or install globally:

\`\`\`bash
npm install -g ./salesforce-b2c-tooling-sdk-${version}.tgz \\
               ./salesforce-b2c-cli-${version}.tgz
\`\`\`

> **Note:** Both packages must be installed together since the CLI depends on the SDK.
