+# Environment Variables in Turborepo
+
+Turborepo provides fine-grained control over which environment variables affect task hashing and runtime availability.
+
+## Configuration Keys
+
+### `env` - Task-Specific Variables
+
+Variables that affect a specific task's hash. When these change, only that task rebuilds.
+
+```json
+{
+  "tasks": {
+    "build": {
+      "env": ["DATABASE_URL", "API_KEY"]
+    }
+  }
+}
+```
+
+### `globalEnv` - Variables Affecting All Tasks
+
+Variables that affect EVERY task's hash. When these change, all tasks rebuild.
+
+```json
+{
+  "globalEnv": ["CI", "NODE_ENV"]
+}
+```
+
+### `passThroughEnv` - Runtime-Only Variables (Not Hashed)
+
+Variables available at runtime but NOT included in hash. **Use with caution** - changes won't trigger rebuilds.
+
+```json
+{
+  "tasks": {
+    "deploy": {
+      "passThroughEnv": ["AWS_ACCESS_KEY_ID", "AWS_SECRET_ACCESS_KEY"]
+    }
+  }
+}
+```
+
+### `globalPassThroughEnv` - Global Runtime Variables
+
+Same as `passThroughEnv` but for all tasks.
+
+```json
+{
+  "globalPassThroughEnv": ["GITHUB_TOKEN"]
+}
+```
+
+## Wildcards and Negation
+
+### Wildcards
+
+Match multiple variables with `*`:
+
+```json
+{
+  "env": ["MY_API_*", "FEATURE_FLAG_*"]
+}
+```
+
+This matches `MY_API_URL`, `MY_API_KEY`, `FEATURE_FLAG_DARK_MODE`, etc.
+
+### Negation
+
+Exclude variables (useful with framework inference):
+
+```json
+{
+  "env": ["!NEXT_PUBLIC_ANALYTICS_ID"]
+}
+```
+
+## Complete Example
+
+```json
+{
+  "$schema": "https://turborepo.dev/schema.v2.json",
+  "globalEnv": ["CI", "NODE_ENV"],
+  "globalPassThroughEnv": ["GITHUB_TOKEN", "NPM_TOKEN"],
+  "tasks": {
+    "build": {
+      "env": ["DATABASE_URL", "API_*"],
+      "passThroughEnv": ["SENTRY_AUTH_TOKEN"]
+    },
+    "test": {
+      "env": ["TEST_DATABASE_URL"]
+    }
+  }
+}
+```
