You will first have to upgrade to Joomla 1.5. To do this, read the tutorial provided on the Joomla Docs
Joomla 1.0 to 1.5 migrator
Once done, download and install JUpgrade which is a component that will upgrade your Joomla 1.5 site to 2.5
Once you have Joomla 2.5 up and running, enter the admin panel and go to the component "Joomla Update" and select the global "options" icon (top right in your screen). Change the settings from Long Term Release (LTS) to STS and save. Now go back to Joomla update and you will see that the 3.x version is available! Click UPDATE and within seconds your site will be on Joomla 3
Please do bare in mind that this process will not upgrade your Joomla 1.0 3rd party extensions therefore you will need to install the J3 versions or simply find alternatives.
Please also consider that it might be quicker and easier to actually create your website again and start from scratch with Joomla 3.1.5
Hope this helps
