             <ul>
-                <li>Retraction acceleration: This will affect whether the retraction speed can actually be reached. The gcode below does not include any changes to what is set on your printer. You can change this with <a href="https://marlinfw.org/docs/gcode/M204.html" target="_blank">M204</a> and the <b>R</b> argument.</li>
-                <li>Slicer settings such as coast and wipe: Coast stops extrusion slightly early to assist retraction. This varies from slicer to slicer and isn't always necessary to tune. Wipe moves the nozzle back towards the recently printed geometry to wipe ooze off. If you are having trouble reducing stringing, it may be a good option.</li>
-                <li>Travel feedrate: A travel move is one where the printer moves to a new location without extruding. The slower this move is, the more time filament will have to ooze from the nozzle and add to stringing.</li>
+                <li>Retraction acceleration: This will affect whether the retraction speed can actually be reached. The gcode generator below does not include any changes to what is set on your printer. You can change this with <a href="https://marlinfw.org/docs/gcode/M204.html" target="_blank">M204</a> and the <b>R</b> argument.</li>
+                <li>Slicer settings such as coast and wipe: Coast stops extrusion slightly early to assist retraction. It effectively lets the hot end 'run dry' at the end of the printing movement to reduce ooze. This varies from slicer to slicer and isn't always necessary to tune.
+                    <br />Wipe moves the nozzle back towards the recently printed geometry to wipe ooze off. If you are having trouble reducing stringing, it may be a good option.
+                    <br />Both coast and wipe are turned off in the gcode generator below.</li>
+                <li>Travel feedrate and acceleration: A travel move is one where the printer moves to a new location without extruding. The slower this move is, the more time filament will have to ooze from the nozzle and add to stringing. The feedrate is set to 100mm/sec in the gcode generator below, and does not include any changes to what is set on your printer for acceleration. You can change travel acceleration with <a href="https://marlinfw.org/docs/gcode/M204.html" target="_blank">M204</a> and the <b>T</b> argument.</li>
                 <li>Linear advance: Linear advance, covered later in this guide, can drastically improve the accuracy of our extrusion. It has a significant impact of retraction (reducing the need), so after configuring linear advance you may need to revisit retraction.</li>
                 <li>Slicer differences: The gcode generated below was originally sliced by Simplify3D. The settings you establish should translate to your slicer quite well but there may be idiosyncrasies. For instance, Cura measures extra restart distance in volume rather than length.</li>
