## Install via Composer

vendor/bin/typo3 extension:setup
```
**Step 2.** Go to TYPO3 Backend > T3Planet Shop. Start a free trial, purchase, browse products, or add your license key.
**Step 4.** Run Composer Command
We have already sent the license key & composer credentials (like username, license key) via Email. If you need any help, then write to our support team [https://t3planet.de/support](https://t3planet.de/support)
```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
composer config repositories.t3planet '{
"type": "composer",
"url": "https://composer.t3planet.cloud",
"only": ["nitsan/"]
}'
```
**Example:**
If installing the extension **ns\_t3ai** package, use the following command:
```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
composer config repositories.nitsan '{
"type": "composer",
"url": "https://composer.t3planet.cloud",
"only": ["nitsan/ns-t3ai"]
}'
```
If you don’t know the exact ``, check the **composer.json** file in the repository. The package name can be found in the first line as shown below:
```json theme={"theme":{"light":"github-light","dark":"github-dark"}}
"name": "nitsan/ns-t3ai"
```
```python theme={"theme":{"light":"github-light","dark":"github-dark"}}
composer config http-basic.composer.t3planet.cloud

composer req nitsan/ --with-all-dependencies
