+If you just want to run without having to install any packages, just run the following commands:
+
+```shell
+docker run -e ... fazenda/hacker-scripts-{PROJECT}
+```
+
+Don't forget to pass the environment variables before with the '-e' in front followed by it, for example:
+
+```shell
+docker run -e KUMAR_EMAIL="kumar.asshole@example.com" -e GMAIL_USERNAME="" -e GMAIL_PASSWORD="" fazenda/hacker-scripts-kumar-asshole

+- `fucking-coffe`
+- `hangover`
+- `kumar-asshole`
+- `smack-my-bitch-up`
+
+And if you want to make your own build, just run the `make` command inside the [Dockerfiles](./Dockerfiles) folder, passing the following arg:
