 The executable is configured to store caches to `$JULIA_LSP_STORAGE` if defined, otherwise it defaults to `../store`
 relative to where the executable is located.
 
+## Symbol caches
+
+Symbols will automatically be downloaded to the store cache. To disable symbol downloads from the symbol server, set the
+`SYMBOL_CACHE_DOWNLOAD` environment variable to `0`, for example:
+
+```sh
+$ SYMBOL_CACHE_DOWNLOAD=0 julia-lsp "<julia_env_path>"
+```
+
+To configure the symbol server (default is `https://www.julia-vscode.org/symbolcache`), set the `SYMBOL_SERVER`
+environment variable, for example:
+
+```sh
+$ SYMBOL_SERVER=https://symbol-server julia-lsp "<julia_env_path>"
