+### Compression
+
 To compress files and folders, use `List<DocumentFile>.compressToZip()` extension function:
 
 ```kotlin
-// make sure you have an URI access to /storage/emulated/0/Documents, otherwise it will return null
-val targetZipFile = DocumentFileCompat.createFile(baseContext, basePath = "Documents/compress test.zip", mimeType = "application/zip")
-if (targetZipFile != null) {
-  listOf(folder).compressToZip(baseContext, targetZipFile, deleteSourceWhenComplete = false, updateInterval = 500).collect {

-      is ZipCompressionResult.CountingFiles -> Timber.d("Calculating...")
-      is ZipCompressionResult.Compressing -> Timber.d("Compressing... ${it.progress.toInt()}%")
-      is ZipCompressionResult.Completed -> Timber.d("Completed: ${it.zipFile.fullName}")

+### Decompression

+FYI, decompressing ZIP files is also easy:
+
+```kotlin
+ioScope.launch {
+  file.decompressZip(baseContext, targetFolder)
