It is now possible to upload YouTube videos via wikiHow. Right now this functionality is only in a test phase, so while you are encouraged to make and upload videos that may help explain articles, please do not add videos directly to articles at this time. Follow these steps to upload videos and add them to the Video namespace.

[edit] Steps

Click on the "Upload Video" link in the Editing tools menu.
Read the instructions on the wikiHow:Upload Video page. Be sure that the video you plan to upload meets our licensing requirements and is compatible with YouTube's system.
Click on the "Upload YouTube video here" link to be brought to the special video upload page.
Fill in the upload form with the title for your video, the description of the video, and its keywords. This is the information that will be used to identify the video on YouTube.
Click on the "Submit" button. You will be brought to an upload screen.
Click on the "Browse" button to look for the video on your computer.
Locate the video and then click "Upload" to upload the video.
Wait. Depending upon the size of the video and the speed of your connection, it may take some time to upload and process the video.
Look for the confirmation screen; understand that it may take YouTube's system a few minutes to process your uploaded video and make it available for viewing.
Use the displayed code from the confirmation screen (e.g., "{{#ev:youtube|25hlFfGTGEo}}") to add the video to a page in the Video namespace.

[edit] Tips

YouTube has a great deal of information on improving your video-making skills.
Experiment with different ways of using videos to illustrate your how-to article.
