<h1>Neon text example using GIMP</h1>
<h2>Prepare your gimp canvas</h2>
<p>Start with a new clean canvas lets say 640px width and 480px height.</p>
<h2>Add some text</h2>
<p>Choose a font you like but I recommend to use an italic text. Now type your word(s).</p>
<p>Right click on the layer with the text and choose Text to Path.</p>
<p>Go to the Edit menu and choose Stroke Path.</p>
<p>In the Stroke Path dialogue choose Stroke with Paint Tool and hit the Stroke button.</p>
<h2>Optional</h2>
<p>You may now need to resize the selection because the text comes too close to the edge and gets chopped off.</p>
<p>Go to Layer-Layer Boundry Size and increase the layer width, centreing the text within the increased layer.</p>
<h2>Back to the necessary</h2>
<p>Select Filters > Alpha to Logo >Neon and click on the OK button.</p>
<h2>Done!</h2>
