+## EFS Configuration
+
+You can use [Amazon EFS with Lambda](https://docs.aws.amazon.com/lambda/latest/dg/services-efs.html) by adding a `fileSystemConfig` property in the function configuration in `serverless.yml`. `fileSystemConfig` should be an object that contains the `arn` and `localMountPath` properties. The `arn` property should reference an existing EFS Access Point, where the `localMountPath` should specifiy the absolute path under which the file system will be mounted. Here's an example configuration:
+
+```yml
+# serverless.yml
+service: service-name
+provider: aws
+
+functions:
+  hello:
+    handler: handler.hello
+    fileSystemConfig:
+      localMountPath: /mnt/example
+      arn: arn:aws:elasticfilesystem:us-east-1:111111111111:access-point/fsap-0d0d0d0d0d0d0d0d0
+    vpc:
+      securityGroupIds:
+        - securityGroupId1
+      subnetIds:
+        - subnetId1
+```
