+# duniter-mini-client
+
+## Requirements
+
+- `sudo apt install libssl-dev`
+
+## Build
+
+    cargo build
+
+## Usage
+
+    duniter-mini-client lookup cgeek
+
+By default, mini-client will target `https://g1-test.duniter.org`. To use another node, change `DUNITER_NODE` environment variable :
+
+    DUNITER_NODE=https://g1.cgeek.fr duniter-mini-client lookup cgeek
