 #### Update
-It's recommended that you keep your gulp tasks and packages up to date, luckily
-this is very easy with `genertor-jekyllized`! All you need to do is run `yo
-jekyllized:update` and you'll be up to date. If you want to skip the
-installation and only update you can run it with `--skip-install`. **NOTE:**
-Running `yo jekyllized:update` will overwrite any changes made to `package.json`
-and your gulp files, so back them up!
+To update the generator, run `npm update -g generator-jekyllized` and then run
+`yo jekyllized:update` and it will update your packages and gulp tasks. You can
+skip installing dependencies by running it with `--skip-install`. **NOTE:**
+Updating will overwrite any changes you've done to your gulp tasks and
+package.json, so back them up before running it! It will ask before overwriting
+though, so you can see the diff before applying it.
