Gladly :) First visit https://d.tube/ and log in using your handle (gratefulayn) and your private posting key (Wallet > Permissions > Show Private Key). Once you're there, click on the upwards arrow at the top right corner of your browser to upload a video.

On the upload page, drag the video you want to upload into the center box. Then give your video a title, description, and tags. Click "Upload Snap" to upload a thumbnail. Once your video has been uploaded, click on the red "Submit" button at the bottom of the page & you're done!
