+# CDK Construct for adding config.json file to a Lambda Function
+
+When using Lambda@Edge, a function cannot use environment variables.
+This CDK Construct uses a Custom Resource to inject a `config.json`
+file with user provided values into an existing function, and
+publishes a new version that is ready to be used as part of a
+CloudFront Distribution.
+
+Inspired by similar mechanism in https://github.com/aws-samples/cloudfront-authorization-at-edge/
+
+## Usage
+
+```bash
+npm install @henrist/cdk-lambda-config
+```
+
+Using the construct:
+
+```ts
+const originalFunction = lambda.Function.fromFunctionArn(...)
+const updatedFunction = new LambdaConfig(this, "UpdatedFunction", {
+  function: originalFunction,
+  config: {
+    Key1: "Some value",
+    Nested: {
+      Key2: "Other value",
+    },
+  },
+  nonce: "1", // See TSDoc.
+}
+// Can now retrieve the new version:
+updatedFunction.version
+```
+
+Read from within the handler:
+
+```ts
+const fs = require("fs")
+const path = require("path")
+const config = JSON.parse(
+  fs.readFileSync(path.join(__dirname, "config.json"), "utf-8"),
+)
+```
