 ### Installation
 
+The following commands install `repl` in `/usr/local/bin` and
+`repl.1`, its man page, in `/usr/local/man`:
+
     $ make
-    $ mv repl /usr/bin/repl
+    $ make install
+
+If you want to install it somewhere different from `/usr/local`,
+edit the Makefile and modify the `PREFIX` variable.
+
+To uninstall both binary and man page, run `make uninstall`.
 
 ### Usage
 
     $ repl git
+    git > status
+    On branch master
+    Your branch is up to date with 'origin/master'.
