 2) if the `Project.toml` & `Manifest.toml` (or `JuliaProject.toml` & `JuliaManifest.toml`) files exists in the current project working directory, the current project working directory is used as the environment

+## Configuring symbol cache
+
+By default, the language server is configured to download symbol caches from Julia's symbol server. To disable this, set
+`symbol_cache_download` to `false`:
+
+```lua
+lspconfig.julials.setup {
+    symbol_cache_download = false,
+}
+```
+
+To change the symbol server URL, set the `symbol_server` configuration:
+
+```lua
+lspconfig.julials.setup {
+    symbol_server = "https://symbol-server",
+}
+```
