To create a new LaTeX project, select New > Project... and from the Texlipse category select New Latex project.
The New Latex Project -wizard allows you to choose a name and a template for the project. To start with an empty document, select the Blank template. There are a few templates offered to choose from, and you can add your own by editing a document and setting it as a template (more on that later).
With the wizard you can also configure the output format for the document. In addition, you can configure the structure of the project. This means that you can specify the project main source and output files and define specific directories to be used for project source, output and temporary files. The builder will then handle automatically moving the files around, so you do not need to move your files yourself to avoid a cluttered project view in the package explorer.
