                 <h3>Description</h3>
                         <ul>A simple brush-based trigger which triggers its target once when a players enters it - never a second time in the round.</ul>

+                <h3>Properties</h3>
+                <ul>
+                    <blockquote>
+                    Name - <i>(targetname) (String)</i>
+                            <ul>The targetname that other entities refer to this entity by.</ul>
+<hr>
+                    Delay before trigger - <i>(delay) (Integer)</i>
+                            <ul>Usually the time in seconds before an entity should trigger its target (after being triggered itself).</ul>
+<hr>
+                    Target - <i>(target) (Integer)</i>
+                            <ul>When an entity is activated, it triggers the entity with the name specified by Target.</ul>
+<hr>
+                    Master - <i>(master) (String)</i>
+                            <ul>The name of a multisource (or game_team_master) entity. A master must usually be active in order for the entity to work. Thus they act almost like an on/off switch, in their simplest form, and like an AND gate in the case of the multisource.</ul>
+                    </blockquote>
