+## Exclude Patterns for Assets
+
+When using `lambda.Code.fromAsset(path)` an `exclude` property allows you to ignore particular files for assets by providing patterns for file paths to exclude. Note that this has no effect on `Assets` bundled using the `bundling` property.
+
+The `ignoreMode` property can be used with the `exclude` property to specify the file paths to ignore based on the [.gitignore specification](https://git-scm.com/docs/gitignore) or the [.dockerignore specification](https://docs.docker.com/engine/reference/builder/#dockerignore-file). The default behavior is to ignore file paths based on simple glob patterns.
+
+```ts
+new lambda.Function(this, 'Function', {
+  code: lambda.Code.fromAsset(path.join(__dirname, 'my-python-handler'), {
+    exclude: ['*.ignore'],
+    ignoreMode: IgnoreMode.DOCKER, // Default is IgnoreMode.GLOB
+  }),
+  runtime: lambda.Runtime.PYTHON_3_9,
+  handler: 'index.handler',
+});
+```
+
+You can also write to include only certain files by using a negation.
+
+```ts
+new lambda.Function(this, 'Function', {
+  code: lambda.Code.fromAsset(path.join(__dirname, 'my-python-handler'), {
+    exclude: ['*', '!index.py'],
+  }),
+  runtime: lambda.Runtime.PYTHON_3_9,
+  handler: 'index.handler',
+});
+```
