+# copySync(src, dest, [options])
+
+Copy a file or directory. The directory can have contents. Like `cp -r`.
+
+## Options:
+- overwrite (boolean): overwrite existing file or directory, default is `true`. _Note that the copy operation will silently fail if you set this to `false` and the destination exists._ Use the `errorOnExist` option to change this behavior.
+- errorOnExist (boolean): when `overwrite` is `false` and the destination exists, throw an error. Default is `false`.
+- dereference (boolean): dereference symlinks, default is `false`.
+- preserveTimestamps (boolean): will set last modification and access times to the ones of the original source files, default is `false`.
+- filter: Function to filter copied files. Return `true` to include, `false` to exclude. This can also be a RegExp, however this is deprecated (See [issue #239](https://github.com/jprichardson/node-fs-extra/issues/239) for background).
+
+## Example:
+
+```js
+const fs = require('fs-extra')
+
+// copy file
+fs.copySync('/tmp/myfile', '/tmp/mynewfile')
+
+// copy directory, even if it has subdirectories or files
+fs.copySync('/tmp/mydir', '/tmp/mynewdir')
+```
+
+**Using filter function**
+
+```js
+const fs = require('fs-extra')
+
+const filterFunc = (src, dest) => {
+  // your logic here
+  // it will be copied if return true
+}
+
+fs.copySync('/tmp/mydir', '/tmp/mynewdir', { filter: filterFunc })
+```
