 # Quick start
 ## Installing adr
+Go to the [releases page](https://github.com/marouni/adr/releases) and grab one of the binaries that corresponds to your platform.
+
+Alternatively, if you have a Go developement environment setup you can install it directly using :
+```bash
+go install github.com/marouni/adr
+```
+
 
 ## Initializing adr
+Before creating any new ADR you need to choose a folder that will host your ADRs and use the `init` sub-command to initialize the configuration :
+
+```bash
+adr init /home/user/my_adrs
+```
 
 ## Creating a new ADR
+
+As simple as :
+```bash
+adr new my awesome proposition
+```
+this will create a new numbered ADR in your ADR folder :
+`xxx-my-new-awesome-proposition.md`.
+Next, just open the file in your preferred markdown editor and starting writing your ADR.
