# DApp Manifest

In the root folder `./my-app`, you can declare your application info by changing default values in `.env.local`. Let's say we will change it like this:

#### .env.local

```
PORT=3000
APP_ID=my_app
APP_NAME=My App
AUTHOR_NAME=Sentre
AUTHOR_EMAIL=hi@sentre.io
TAGS=solana,dapps
DESCRIPTION=A DApp Example
GITHUB=https://tuphan-dn.github.io/my-app
```

{% hint style="warning" %}
Please replace all `tuphan-dn` by your username or organization name on Github.
{% endhint %}
