 ## Get it
 *currently only warcraft 3 maps and mpqs are fully supported. Mpqs from other games (WoW, starcraft) might cause problems.*
@@ -33,17 +33,18 @@ Quick API Overview:
 
 Jmpq provides the OpenOptions `READ_ONLY` which should be selfexplanatory and `FORCE_V0` which forces the mpq to be opened like warcraft3 would open it, ignoring optional data from later specifications for compatability.
 ```java
-    JMpqEditor e = new JMpqEditor(new File("my.mpq")); //Opens a new editor
+    JMpqEditor e = new JMpqEditor(new File("my.mpq"), MPQOpenOption.FORCE_V0); //Opens a new editor
     e.hasFile("filename") //Checks if the file exists
     e.deleteFile("filename"); //Deletes a specific file out of the mpq
     e.extractFile("filename", new File("target location")); //Extracts a specific file out of the mpq to the target location			
     e.insertFile("filename", new File("file to add"), true); //Inserts a specific into the mpq from the target location	
     e.extractAllFiles(new File("target folder")); //Extracts all files inside the mpq to the target folder. If a proper listfile exists, names will be used accordingly
     e.getFileNames(); //Get the listfile as java HashSet<String>
-    e.close(); //Rebuilds the mpq and applies all changes that were made. Not needed in READ_ONLY mode
+    e.close(); //Rebuilds the mpq and applies all changes that were made. In readonly mode it only closes the filechannel.

 ###Known issues:
-* To work around https://bugs.openjdk.java.net/browse/JDK-4724038 jmpq creates a lot of tempfiles
-* JMPQ doesn't support all decompression algorithms. For compression only zlib is implemented.
+* To work around https://bugs.openjdk.java.net/browse/JDK-4724038 jmpq creates tempfiles for every object in the mpq
+* Unsupported decompression algorithms: sparse, pkware and bzip2
+* Only supported compression is zlib
 * JMPQ doesn't build a valid (attributes) file for now. (which seems to be fine for warcraft3)
