-## Local development
+App designed to work in AWS cloud using lambda functions, SQS and secret manager.
+It has two main components:
+- [events-receiver](src/events-receiver.ts) - responsible for receiving events from Saleor (or custom ones via http) and pushing them to SQS queue.
+- [email-sender](src/emails-sender.ts) - responsible for receiving events from SQS queue via lambda triggers and sending emails.
 
-1. Setup required envs. You can copy `.env.example` to `.env` and adjust it.
+Upon build, it outputs two files. Each, for one component. Both share same environment variables. When deployed to lambda, specify the following handlers:
+- `events-receiver.handler`
+- `emails-sender.handler`
+
+When installing the app in Saleor, it will store it's configuration in the secret manager. Therfore, the secret should be created beforehand with empty object (`{}`) and the name should be specified in  `SECRET_MANAGER_APP_CONFIG_PATH` env.

-   SALEOR_URL=<e.g. https://your.eu.saleor.cloud>
-   STATIC_URL=<where from emails static images will be served>
-   SQS_QUEUE_URL=
+If you want to change supported events, you can do it in the [const](src/const.ts) file editing `SALEOR_EVENTS` or `CUSTOM_EVENTS` constants.

+When adding new events, remember to update [TEMPLATES_MAP](src/lib/emails/const.ts) constant with the proper template and extract email function.
