 ### NBT files
 
+NBTFileHandle allows working with nbt files.
+
 ```java
-// Creating nbt file
-// NBTFile will automatically create the file if it does not exist
-NBTFile file = new NBTFile(new File("directory"), "test.nbt"); // Will be created at ./directory/test.nbt
+// Will automatically create the file if it does not exist
+NBTFileHandle nbtFile = NBT.getFileHandle(new File("directory", "test.nbt"));
 // Setting data 
-file.setString("foo", "bar");
-// Saving file
-file.save();
-
-// Alternatively, you may use helper methods in NBTFile class
-// To read the file without creating it if does not exist:
-ReadWriteNBT nbt = NBTFile.readFrom(file);
-// To save nbt to the file:
-NBTFile.saveTo(file, nbt);
+nbtFile.setString("foo", "bar");
+// Saving the file after applying changes
+nbtFile.save();
+```
+
+Alternatively, you may read the nbt file without maintaining the link to it.
+Unlike NBTFileHandle, the file won't be automatically created if it does not exist.
+
+```java
+File file = new File("directory", "test.nbt");
+// Reading data from file (will return an empty compound if the file does not exist)
+ReadWriteNBT nbt = NBT.readFile(file);
+// Saving nbt to file
+NBT.writeFile(file, nbt);
