 ## 🔩 Architecture
+
 GovTool consists of a Haskell backend and a React Typescript frontend.
 
 ### Backend
+
 GovTool backend implements an API wrapper around an instance of [DB-Sync](https://github.com/IntersectMBO/cardano-db-sync) which interfaces with a [Cardano Node](https://github.com/IntersectMBO/cardano-node).
 The API exposes endpoints making the querying of governance related data from DB-Sync straight forward.

 ### Frontend
+
 GovTool frontend web app communicates with the backend over a REST interface, reading and displaying on-chain governance data.
 Frontend is able to connect to Cardano wallets over the [CIP-30](https://github.com/cardano-foundation/CIPs/blob/master/CIP-0030/README.md) and [CIP-95](https://github.com/cardano-foundation/CIPs/blob/master/CIP-0095/README.md) standards.
