+### Updating angular-cli
+
+To update `angular-cli` to a new version, you must update both the global package and your project's local package.
+
+Global package:
+```
+npm uninstall -g angular-cli
+npm cache clean
+npm install -g angular-cli@latest
+```
+
+Local project package:
+```
+rm -rf node_modules dist tmp
+npm install --save-dev angular-cli@latest
+ng init
+```
+
+Running `ng init` will check for changes in all the auto-generated files created by `ng new` and allow you to update yours. You are offered four choices for each changed file: `y` (overwrite), `n` (don't overwrite), `d` (show diff between your file and the updated file) and `h` (help).
+
+Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after `ng init` finishes.
+
+**The main cause of errors after an update is failing to incorporate these updates into your code**. 
+
+You can find more details about changes between versions in [CHANGELOG.md](https://github.com/angular/angular-cli/blob/master/CHANGELOG.md).
