+By default, with no arguments, git log shows the most recent commits first.
+
+If we want to limit the number of log entries displayed we can use a number as an option, such as -3 to show only the last three entries. 
+
+```bash
+$ git log -3
+```
+
+A very useful option is the --patch or -p. This command shows the difference of each commit. This can be very helpful to see what has changed on the last commited changes.
+
+```bash
+$ git log -p
+```
+
+If we want to see a few stats for each commit we can use the --stat command.
+
+```bash
+$ git log --stat
+```
+
+With the --graph command we will be able to draw a graphical representation of the commits. It will display an ASCII graph of the branch and merge history beside the log output. 
+We can use this command with the --oneline command to display the commits in an alternate format in one line. 
+
+```bash
+$ git log --graph --oneline
+```
