This plugin embeds a WebODF Viewer into WordPress.
10+
11+
== Description ==
12+
13+
This plugin embeds a WebODF Viewer into WordPress. See www.webodf.org for more details on WebODF.
14+
15+
== Usage ==
16+
17+
Navigate to a Open Document file in your WP blog's media library and press the button "Insert WebODF Viewer".
18+
Alternatively you can manually insert the WordPress shortcode `[webodf_viewer /path-to-some-file.odt]` to embed
19+
any `*.odt`, `*.odp`, or `*.ods` documents at that location.
20+
21+
The plugin also provides a settings panel for adjusting the width and height of the embeded element (iframe).
22+
23+
== Installation ==
24+
25+
1. Upload the whole `webodf-viewer` directory and content to the `/wp-content/plugins/` directory
26+
2. Activate the plugin through the 'Plugins' menu in WordPress
27+
28+
(or do the automatic stuff from the /wp-admin/...)
29+
30+
