It's easy to add a new chart source.

• If it's an single download of an existing country, just add a new list item below the related country. Enter the name of the region and the URL. Save it.

If you like to add a new country or multiple files (cells, updates, etc.), then use a new page.

• Add a list item below the headline of the related continent. Add a link for the new page within the related namespace (enc: or rnc:) and the name of the country. Save it and click the link. Copy the content of the Template to the created page and fill in the placeholders. Save it.

If you're in total hurry.

• Open the notepad and just drop the URL for later revision.

Let's assume you found a chart source of Atlantis in ENC format.

Open the Vector Charts (ENC) directory. Select Europe and click Edit. At the end of the list add two list items with one internal link (shown below or use the buttons above). Save it and click on the created link.

    * ...
    * Greece
      * [[enc:atlantis | Atlantis]]

On the empty page click on “Create this page” in the Toolbar. Copy the content of the pre-formated template into the new page. And fill in the placeholders, like here:

====== Atlantis ======

Region:
  * Greece (Ελλάδα)
  * Ionian Sea (Ιόνιο Πέλαγος)

It's quite easy. The complete Wiki syntax can be found here: Formatting Syntax.

When updating chart sources put the former URLs at the end of the page.

If the files are still available list them under “Alt. Sources”. When they point to older versions list them under “Versions”. If the files are gone mark them as deleted.

This wiki has a very basic structure. It should be self-explaining.

In details: There's a list for vector charts and for raster charts. Single file sources for a complete region or a country are direct links. A page groups sources with multiple files like cells, updates, etc. and collects different or alternative sources. At last: The pages are grouped with a “namespace” (a prefix). The namespace for vector charts is “enc:” and for raster charts it's “rnc:”.

So the path for a raster charts collection of hawaii would be “rnc:hawaii”. That's all.

It's simple when you see it.

Important: Just add open accessible, free of charge and most important legally sources.
