+# 🤖 Gap - WIP
+
+Gap is a modular REST API with which you can interact to view, add and remove content.
+It's a project for practicing my Go skills so there's nothing really fancy, just me learning...
+
+## 📑 Features
+
+You can launch it from the command line and add some arguments.
+```bash
+$ gap -h
+Usage: gap [-p PORT | -h]
+$ gap -p 8080
+Server is running at 'http://localhost:8080'
+```
+
+## 🔨 Building
+
+#### 🐁 Go
+```bash
+$ go build .
+```
+
+#### ❄️ Nix
+```bash
+$ nix build .#
+```
