+Record a terminal command, then press 'Control + d' to exit.
+
+```sh
+script --timing=time.log stat.txt
+ls -a
+ls -al
+stat ~/.bashrc
+^D
+```
+
+Replay the session:
+
+```sh
+scriptreplay --timing=time.log stat.txt
+```
+
+Try a bare command, without any timing:
+
+```sh
+script -c 'top | lolcat' loltop
+nl loltop
+```
+
+Has your terminal messed up?
+Is the cursor hiding?
+Reset it!
+
+```sh
+reset
+```
+If you can't see any keys, keep typing anyway: have faith in your terminal.
+
+This `loltop` file will not play properly as it has no timings file.
+But you can cheat the system and use your other timings file:
+
+```sh
+scriptreplay --timing=time.log loltop
+```
+
+This will mostly not work well, but it shows how the timing file works:
