Whether you’re **creating a meeting** or **joining one via a link**, you’ll always see a **preview screen** first. This gives you a moment to get everything ready the way *you* like it. Here, you can adjust the following:
{% endcolumn %}
{% endcolumns %}
{% columns %}
{% column width="66.66666666666666%" %}
* Choose whether you want to join with your **camera** and **microphone** on *(dMeet will request permission to access your camera and microphone)*
* Update your **avatar** *(Avatar customization is available only for authorized users)*
* Change your **name** and **the room name** that other participants will see during the call
→ So you always enter the room exactly the way you want!
{% endcolumn %}
{% column width="33.33333333333334%" %}
{% endcolumn %}
{% endcolumns %}
{% hint style="info" icon="face-grin-stars" %}
Once everything looks good, just click **Start Meeting**, and you're all set!
{% endhint %}
