+### Environment variables
+
+Use the `env` property to set environment variables when starting the LSP server:
+
+```json title="opencode.json" {5-7}
+{
+  "$schema": "https://opencode.ai/config.json",
+  "lsp": {
+    "rust": {
+      "env": {
+        "RUST_LOG": "debug"
+      }

+```json title="opencode.json" {5-9}
+{
+  "$schema": "https://opencode.ai/config.json",
+  "lsp": {
+    "typescript": {
+      "initialization": {
+        "preferences": {
+          "importModuleSpecifierPreference": "relative"
+        }
+      }
+    }
+  }
+}
+```
+
+:::note
+Initialization options vary by LSP server. Check your LSP server's documentation for available options.
