Android Uploading App to Marketplace

I have a project that I need to upload to the market. What is getting my really confused is the signing. I've seen lots of different tutorials all using different methods and the official Android dev site makes it worse. I've tried a few but they either don't seem to work or I don't really understand the process.

Are there any developers who can provide a easy to understand step by step link or tutorial that they have us开发者_JS百科ed (or created)?

Thanks in advance.

The easiest way I know is the eclipse method. Right click on your project -> android tools -> export signed application package.

The rest is done by the assistent.
