+### Screens
+
+pstop has 5 different screens:
+* Latency mode: order table activity by the time waiting to perform operations on them.
+* Ops (operations) mode: order table activity by the number of operations MySQL performs on them.
+* I/O mode: show where MySQL is spending it's time in file I/O.
+* Locks mode: show order based on table locks
+* User mode: show ordering based on how long users are running queries, or the number of connections they have to MySQL.
+
+### Keys
+
+The following keys allow you to navigate around the different pstop displays or to change it's behaviour.
+
+* h - gives you a help screen.
+* - - reduce the poll interval by 1 second (minimum 1 second)
+* + - increase the poll interval by 1 second
+* q - quit
+* t - toggle between showing the statistics since resetting pstop started or you explicitly reset them (with 'z') [REL] or showing the statistics as collected from MySQL [ABS].
+* z - reset statistics. That is counters you see are relative to when you "reset" statistics.
+* <tab> - change display modes between: latency, ops, file I/O, lock modes and user modes.
+* left arrow - change to previous screen
+* right arrow - change to next screen
