+# High level Architecture
+
+
+Paper Badger is both an API and a UI, and it also integrates and uses data from different sources.
+The following image contains the main building blocks of the system:
+
+![Badges--Proposed-Workflow_1_.pdf](Badges--Proposed-Workflow_1_.pdf?raw=true)
+
+It is recommended to keep an eye on the [Roadmap #17](https://github.com/mozillascience/PaperBadger/issues/17) to see changes that may affect this document in the near future.
+
+## Main building blocks
+
+The main building blocks of the system are as follows.
+
+Integration with :
+  - ORCID
+  - A badges Server (currently badgekit-api; being migrated to badgr-server, see [#159](https://github.com/mozillascience/PaperBadger/issues/159))
+
+## Flows
+Flows for the system are as stated in issue [#1](https://github.com/mozillascience/PaperBadger/issues/1)
+
+## Journal submission
+This is a feature that is currently done through a form, but needs to be automated.
+Progress can be followed in [#160](https://github.com/mozillascience/PaperBadger/issues/160)
+
+# The Stack
+
+Paper Badger is written in nodejs, using expressjs, MongoDB, Redis, and reactjs for the front end.
+
+The data for Badges comes from API calls to badgekit-api, through badgekit-api-client.
+
+## ORCID integration
+[Setup details](orcid-setup.md) to integrate with ORCID.
+
+## Badges integration
+A badges server has to be available so that Paper Badger can push and pull data from. The file [default.env](../default.env)
+contains the endpoint for the currently available _badgekit-api_ server.
