 With the above structure inlining `icons.svg` would look like:

 ```html
 <img inline src="images/icons.svg">
 ```
 
 If an alias was in place for the images directory, i.e.
+
 ```javascript
 'img': path.join(__dirname, 'src', 'images')

 Then the svg can be inlined with: `<img inline src="~img/icons.svg">`. This method would require the use of **loaders** on your templates as shown above in point 2.

+### Incorrect file paths or URLs

 If for any reason the path to a local SVG file is incorrect, or the file fails to be read, or an image retrieved with an URL fails to download, the webpack build process will fail with an error, like `ENOENT`.
 
 ### Duplicated attributes

 All the attributes of a `<img/>` element excepting `src` and `inline` will be copied to the inlined `<svg/>` element. Attributes like `id` or `class` will be copied to the resulting root of the `<svg/>` element and if the original SVG file already had these attributes they will be duplicated (and not replaced) on the resulting `<svg/>` element, though the attributes coming from the `<img/>` will appear first and [any subsequent duplicated attribute from the original SVG will be ignored by the browser](https://stackoverflow.com/questions/26341507/can-an-html-element-have-the-same-attribute-twice).

-- `svgoConfig`: defaults to `undefinded`. to configure SVGO (module used to optimise your SVGs), add an `svgoConfig` object to your `html-webpack-plugin` config:
+- `svgoConfig`: defaults to `[]`. [SVGO](https://github.com/svg/svgo) is used to optimise the SVGs inlined. You can configure SVGO by setting this `svgoConfig` `Array` with the [SVGO plugins](https://github.com/svg/svgo#what-it-can-do) you need in the same way it's done in this [SVGO official Node.js example](https://github.com/svg/svgo/blob/master/examples/test.js).
+
+ Note `svgoConfig` is an array of `Object`s that will be assigned to the `.plugins` SVGO config variable by `html-webpack-inline-svg-plugin`. You don't need to pass an `Object` with a `plugins` property assigned an array of SVGO plugins, just pass the array:
 
  ```javascript
  plugins: [
- new HtmlWebpackPlugin({
- svgoConfig: {
- removeTitle: false,
- removeViewBox: true,
- },
- }),
- new HtmlWebpackInlineSVGPlugin()
+ new HtmlWebpackPlugin(),

+ {
+ removeViewBox: false
+ },
+ {
+ inlineStyles: {
+ onlyMatchedOnce: false
+ }
+ }
+ ]
+ })
  ]
  ```
 
- For a full list of the SVGO config (default) params we are using check out: [svgo-config.js](svgo-config.js). The config you set is merged with our defaults, it does not replace it.
+ `html-webpack-inline-svg-plugin` modifies one SVGO default: `cleanupIDs`, from `true` to `false`, since IDs allow to reference individual symbols. You can still override this or any other SVGO plugin default configuration with this `svgoConfig` option.
