+### deno install --global --compile [PACKAGE_OR_URL]
+
+Use this command to compile a package or script into a standalone,
+self-contained binary. The resulting executable can be distributed and run
+without requiring Deno to be installed on the target system.
+
+```shell
+$ deno install --global --compile -A npm:@anthropic-ai/claude-code
+```
+
+This combines the behavior of [`deno compile`](/runtime/reference/cli/compile/)
+with global installation — producing a native binary placed in the installation
+root (same as `--global` without `--compile`).
