So, you've planned your channel and you have some videos you want to share with the world. You'll need a YouTube channel so you can upload your videos.
Let's create a YouTube channel by following these steps:
If you don't already have one, create a Google account for yourself at https://accounts.google.com/SignUp.
Head over to YouTube at https://www.youtube.com and sign in. You'll have an account with YouTube because it's part of Google, but you won't have a channel yet.
Go to https://www.youtube.com/channel_switcher. Click on the Create a new channel button.
Follow the instructions on screen to create your channel.
Customize your channel by uploading images to your profile photo or channel art and adding a description using the About tab.
Here's my channel:
