 # Bismuth Protocol
 
 The Bismuth protocol is a thin wrapper for any protocol that adds TLS-like features, without being TLS on its own.
+
+## Application
+### Building
+
+Git clone this repository and check out a release (except for development, as you probably don't wanna develop on a release version):
+```bash
+git clone https://git.greysoh.dev/imterah/bismuthd
+git checkout v0.1.0
+```
+Then, build the code:
+```bash
+go build .
+```
+
+### Usage
+To get started, you'll need an exported armored public and private key pair.
+
+After that, for usage help, run the help command:
+```
+./bismuthd help
+```
