+## Environment
+
+The following options control the launch environment of the Fluss server processes, such as the JVM options and the directory for process id files. They are set in `conf/server.yaml` and are applied by the startup scripts under `bin/` when starting the CoordinatorServer and TabletServer.
+
+| Option                           | Type   | Default | Description                                                                                                                                                                             |
+|----------------------------------|--------|---------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| env.java.home                    | String | (None)  | Path to the JDK/JRE used to run the Fluss processes. If not set, the system `JAVA_HOME` or the `java` binary found on the `PATH` is used.                                               |
+| env.java.opts.all                | String | (None)  | JVM options applied to all Fluss server processes, i.e. both the CoordinatorServer and the TabletServer, for example `-Xmx4g -XX:+UseG1GC`. When `FLUSS_ENV_JAVA_OPTS` is not already set, the startup scripts prepend `-XX:+IgnoreUnrecognizedVMOptions` to the configured options and, on JDK 18+, append `-Djava.security.manager=allow`. |
+| env.java.opts.coordinator-server | String | (None)  | Additional JVM options applied only to the CoordinatorServer process. They are appended after `env.java.opts.all`.                                                                     |
+| env.java.opts.tablet-server      | String | (None)  | Additional JVM options applied only to the TabletServer process. They are appended after `env.java.opts.all`.                                                                          |
+| env.pid.dir                      | String | /tmp    | The directory where the `*.pid` files of the running Fluss processes are stored.                                                                                                       |
+
+:::note
+The logging-related environment options (`env.log.dir`, `env.log.level`, `env.log.max` and `env.stdout-err.redirect-to-file`) are described in the [Logging](observability/logging.md) documentation.
