+# Scripts
+
+## Download and Installation
+
+Use the `install_binary.sh` or `install_distribution.sh` scripts to download and install the sparrow binary on a machine.
+
+`install_binary.sh` will download and extract the packed binary from GitHub.
+
+`install_distribution.sh` will detect the systems distribution and installs the right version of the sparrow with the common package manager.
+
+## Config
+
+Use the `get_config.sh` script to download a remote startup configuration file.
+Pass the sparrow name, the url where the config is located and the token that is needed for authentication.
+The token will be used in the config for the sparrow registration and check configuration as well!
