Start a new page for each concept. Choose a short but meaningful name that starts with an uppercase letter. Don't use spaces in the name; use so called CamelCase or underscores instead.
Description – Explain what your concept is all about.
Content – Palettes, demonstration and mockups go here. Follow with references and inspirational material.
Contributions – List contributors to the project.
Comments – At the bottom of your page, start a comment section == Comments == .
Don't include huge images in the page directly. Rather restrict them to 800 pixels in width and link to the full size image.
Submissions should be made in formats that can be read by software available from the Ubuntu Repositories. Preferred image formats include XFC, SVG, and PNG. Preferred sound formats include WAV, FLAC and OGG Vorbis. Master files, which may be further edited, should be maintained in non-lossy formats and made available to the community. Preserving vector graphics, raster layers and channels is important for such materials.
