+* use-package tips
+  Some notes about *use-package*
+  - *:ensure* if true will install the package if not installed
+    It won't update packages. See auto-package-update for keeping all
+    packages up to date
+  - *:init* keyword to execute code *before* a package is loaded. It
+    accepts one or more foorms, up to the next keyword
+  - *:config* can be used to execute code *after* a package is loaded.
+    In cases where loading is done lazily (see more about autoloading
+    below), this execution is deferred until after the autoload
+    occurs
+  - *:custom* permite configurar variables con syntaxis simplificada
+  - *:bind*
+  - *bind-keymap*
+  - *:mode* and *:interpreter*
+  - *:magic*
+  - *:hook*
+  - *:if*
+  - *:defer* En general use-package intenta aplicar lazy loading, pero
+    en algún paquete es necesario especificarlo explicitamente
+  - *:demand* Este es el contrario del anterior, para paquetes
+    que queremos cargar de inmediato
+  - *:diminish* and *:delight* changes minormode display in status line
+
 * Interface tweaks
