-The `native` image contains a native, statically-linked executable created with GraalVM
+The `native` image contains a native, statically-linked executable created with GraalVM Native Image
 that has no userspace dependencies. It also embeds the memcache plugin inside the executable.
 Use this image for maximum efficiency and minimal memory footprint. 
 
-## Which image shoud I use?
+The `jlink` image contains a custom Java runtime created with GraalVM's Jlink
+that only depends on glibc. It also contains the memcache plugin in the module path.
+Use this image for best performance.
+
+## Which image should I use?
 The `native` image uses Java's SerialGC, so it's ideal for constrained environment like containers or small servers,
 if you have a lot of resources and want to squeeze out the maximum throughput you should consider the
 `vanilla` or `memcache` image, then choose and fine tune the garbage collector.
