+Utility methods for Material Design Icons' Build scripts.
+
+## Getting Started
+
+The `@mdi/util` package relies on the `@mdi/svg` package. Any version of `@mdi/svg` can be used.
+
+```
+npm install @mdi/svg @mdi/util
+```
+
+- getVersion()
+- getMeta([bool withPaths])
+- write(file, data)
+- read(file)
+- exists(file)
+
+### getVersion()
+
+This returns the version of `@mdi/svg` referenced in the `package.json`.
+
+**returns** semver string `major.minor.build`
+
+### getMeta([bool withPaths])
+
+The main use of this library is to get all the icon data from the `meta.json`. Since the `meta.json` does not contain the SVG path data this method optionally allows this to be added to the object.
+
+Please reference [meta.json](https://github.com/Templarian/MaterialDesign-SVG/blob/master/meta.json) for more information.
+
+**returns** icon array []
+
+### write(file, data)
+
+```
+import { write } from '@mdi/util'
+
+write('file.txt', 'Hello World!')
+```
+
+### read(file)
+
+```
+import { read } from '@mdi/util'
+
+const foo = read('file.txt')
+```
+
+**returns** string of file contents
+
+### exists(file)
+
+```
+import { exists } from '@mdi/util'
+
+if (exits('file.txt')) {
+    // file exists!
+}
+```
+
+**returns** bool `true`/`false` if file exists
