+### How do I access Environment Variables?
+
+`process.env` can be used to access [Environment Variables](/docs/basic-features/environment-variables.md) from Middleware. These are evaluated at build time, so only environment variables _actually_ used will be included.
+
+Any variables in `process.env` must be accessed directly, and **cannot** be destructured:
+
+```ts
+// Accessed directly, and not destructured works. process.env.NODE_ENV is `"development"` or `"production"`
+console.log(process.env.NODE_ENV)
+// This will not work
+const { NODE_ENV } = process.env
+// NODE_ENV is `undefined`
+console.log(NODE_ENV)
+// process.env is `{}`
+console.log(process.env)
+```
