 ### Prerequisites
 
-* [Java JDK](https://www.oracle.com/java/technologies/downloads/)
+* [Java JDK 17+](https://www.oracle.com/java/technologies/downloads/)
 
 !!! note "Linux open file limit"
 
     If synchronizing to Mainnet on Linux or other chains with large data requirements, increase the
     maximum number of open files allowed using `ulimit`. If the open files limit is not high
     enough, a `Too many open files` RocksDB exception occurs.
 
+!!! tip
+
+    We recommend installing [jemalloc](https://jemalloc.net/) to reduce memory usage.
+    If using Ubuntu, you can install it with the command: `apt install libjemalloc-dev`.
