+Gdb gives each breakpoint a number.  In Vim the number shows up in the sign
+column, with a red background.  You can use these gdb commands:
+- info break	list breakpoints
+- delete N	delete breakpoint N
+You can also use the `:Clear` command if the cursor is in the line with the
+breakpoint, or use the "Clear breakpoint" right-click menu entry.

 will break the debugger.
 
+Gdb has some weird behavior, the plugin does its best to work around that.
+For example, after typing "continue" in the gdb window a CTRL-C can be used to
+interrupt the running program.  But after using the MI command
+"-exec-continue"  pressing CTRL-C does not interrupt.  Therefore you will see
+"continue" being used for the `:Continue` command, instead of using the
+communication channel.
