<h4>Usage</h4>
<p>To insert an image of the flag for Letter A in a post or page, use the shortcode <code>[signal-flag a]</code>. You can use the following flags with the corresponding codes:<br />
* Alphabet flags A-Z (codes <code>a</code>–<code>z</code>)<br />
* Numeral pennants 0-9 (codes <code>n0</code> – <code>n9</code>)<br />
* Answering pennant (AP) (code <code>ap</code>)<br />
* 1st, 2nd and 3rd substitute (codes <code>s1</code>–<code>s3</code>)<br />
* Various flags defined in the Racing Rules of Sailing (codes <code>black</code>, <code>blackwhite</code>, <code>blue</code>, <code>green</code>, <code>greenwhite</code>, <code>red</code>, <code>yellow</code>)</p>
<p>There are different sets of flags selectable from the admin settings page.</p>
<h4>About the flag images</h4>
<p>Images are embedded in the page using the SVG vector format (much quicker than loading a separate image file) and eight sets of flag images are included with the following options:<br />
* with or without outlines for ease of use on white backgrounds (including when printed)<br />
* rectangular (4:3 aspect ratio) and square shapes for letter flags<br />
* in ‘natural’ or ‘primary’ colours.</p>
