+A simple server to store, search and download resources (books, articles, etc...).
+Its uses an **sqlite3** database to register resources.
+
+**NOTE**: The UI is dramatically ugly with almost no CSS and no responsiveness with small screens. There's no vocation to build a beautiful UI here, just to demonstrate how easy we can build practicable UI with server side rendering using Go std lib. Ideal for back office.
+
+## Build
+Build the binary `builds/librapi`:
+```bash
+make build
+```
+
+## Run
+```bash
+make run
+```
+You can then access the server through `http://localhost:8585`.
+
+Enjoy !
