+You use the `assets` array inside the build target in `angular.json` to list files or folders
+you want to copy as-is when building your project.
 
 By default, the `src/assets/` folder and `src/favicon.ico` are copied over.
 
 ```json
 "assets": [
-  "assets",
-  "favicon.ico"
+  "src/assets",
+  "src/favicon.ico"
 ]

 ```json

 `glob` is the a [node-glob](https://github.com/isaacs/node-glob) using `input` as base directory.
-`input` is relative to the project root (`src/` default), while `output` is
- relative to `outDir` (`dist` default).
+`input` is relative to the workspace root, while `output` is relative to `outDir`
+(`dist/project-name` default).
 
  You can use this extended configuration to copy assets from outside your project.
  For instance, you can copy assets from a node package:
 
  ```json
 "assets": [
-  { "glob": "**/*", "input": "../node_modules/some-package/images", "output": "./some-package/" },
+  { "glob": "**/*", "input": "./node_modules/some-package/images", "output": "/some-package/" },
 ]
 ```
 
 The contents of `node_modules/some-package/images/` will be available in `dist/some-package/`.
 
 ## Writing assets outside of `dist/`
 
-Because of the security implications, the CLI will always refuse to read or write files outside of
-the project itself (scoped by `.angular-cli.json`). It is however possible to write assets outside
-the `dist/` build output folder during build.
-
-Because writing files in your project isn't an expected effect of `ng build`, it is disabled by 
-default on every assets. In order to allow this behaviour, you need to set `allowOutsideOutDir` 
-to `true` on your asset definition, like so:
-
-```json
-"assets": [
-  {
-    "glob": "**/*",
-    "input": "./assets/",
-    "output": "../not-dist/some/folder/",
-    "allowOutsideOutDir": true
-  },
-]
-```
-
-This needs to be set for every assets you want to write outside of your build output directory.
