-This is a code sharing web application written in next.js using Serverless Functions and MongoDB/FaunaDB as database.
+# fastbin: a text sharing application
 
-## Getting Started
+https://fastbin.lab.divyam.dev
 
-First, run the development server:
+A text sharing application made with microservice architecture in golang.
+Services:
+- API Server (Read and Write)
+- Custom Key Generator Service
+- Database Service
 
-```bash
-npm run dev
-# or
-yarn dev
-```
+To-do:
+- Add data deletion service which removes data after certain time.
+- Make key generator service faster and scalable with bloom filter and redis caching.
