+## Usage
+
+> [!CAUTION]
+> Please note that this module is still in development and could corrupt the audio file.
+
+Reading works in exactly the same way as with TinyTag. \
+Example:
+
+```Python3
+from smalltag import SmallTag
+
+tag = SmallTag.get("test.mp3")
+
+print(tag.title)
+# Example Output: Test
+```
+
+But this module also adds support for writing metadata.
+Just use the `write()`-function on a loaded tag to write the metadata to the file. \
+Example:
+
+```Python3
+from smalltag import SmallTag
+
+tag = SmallTag.get("test.mp3")
+
+print(tag.title)
+# Example Output: Test
+
+tag.title = "Another Test"
+
+tag.write()
+```
+
+When you then load the metadata again, you will see that the title has changed:
+
+```Python3
+from smalltag import SmallTag
+
+tag = SmallTag.get("test.mp3")
+
+print(tag.title)
+# Example Output: Another Test
+```
