-This is a tool to deploy certificates from a [CertWarden](https://www.certwarden.com/) instance.
+This is a simple binary to deploy certificates from a [CertWarden](https://www.certwarden.com/) instance.
+
+## Quick Start
+
+Installation of the required CertWarden instance is out of scope of this documentation. For detailed instructions regarding CertWarden, please visit [it's documentation](https://www.certwarden.com/docs/introduction/)
+
+
+To quickly get started with `certwarden-deploy`, just download the binary...
+
+```shell
+# this downloads certwarden-deploy version 0.1.1 
+# to /usr/local/bin/certwarden-deploy
+sudo wget https://code.lila.network/adoralaura/certwarden-deploy/releases/download/0.1.1/certwarden-deploy-0.1.1-linux-amd64 -O /usr/local/bin/certwarden-deploy
+
+sudo chmod +x /usr/local/bin/certwarden-deploy
+```
+
+... fill out the config file...
+```shell
+vi /etc/certwarden-deploy/config.yaml
+```
+```yaml
+# Base URL of the CertWarden instance
+# required
+base_url: "https://certwarden.example.com"
+
+# Set this to true if your CertWarden instance does not have a publicly trusted 
+# TLS certificate (e.g. it has a self signed one)
+# default is false
+disable_certificate_validation: false
+
+# define all managed certificates here
+certificates:
+
+    # name is a unique identifier that must start and end with an alphanumeric character, 
+    # and can contain the following characters: a-zA-Z0-9._-
+    # required
+  - name: test-certificate.example.com
+
+    # Contains the API-Key to fetch the certificate from the server
+    # required
+
+    api_key: examplekey_notvalid_hrzjGDDw8z
+
+    # action to run when certificate was updated or --force is on
+    action: "/usr/bin/systemd reload caddy"
+
+    # path where to save the certificate
+    # required
+    file_path: "/path/to/test-certificate.example.com-cert.pem"
+```
+
+... and run it!
+```shell
+certwarden-deploy -v
+```
