+# Satisfactory Exporter
+
+This project is a prometheus exporter for the game [Satisfactory](https://www.satisfactorygame.com/).
+It periodically queries a dedicated server via the HTTPS API for metrics and exposes them via an HTTP endpoint.
+
+## Usage
+
+### CLI
+
+```
+Usage: satisfactory-exporter [OPTIONS] --endpoint <ENDPOINT>
+
+Options:
+      --update-interval <UPDATE_INTERVAL>
+          Interval in seconds between each query to the server [env: SE_UPDATE_INTERVAL=] [default: 5]
+      --endpoint <ENDPOINT>
+          Hostname and port of the server to query [env: SE_ENDPOINT=]
+      --token-file <TOKEN_FILE>
+          File containing the bearer token to use for authentication. Mutually exclusive with --token [env: SE_TOKEN_FILE=]
+      --token <TOKEN>
+          Bearer token to use for authentication. Mutually exclusive with --token-file [env: SE_TOKEN=]
+      --allow-insecure
+          Allow insecure connections (e.g., to a server with a self-signed certificate) [env: SE_ALLOW_INSECURE=]
+      --listen <LISTEN>
+          Address:Port to which the server will listen [env: SE_LISTEN=] [default: 127.0.0.1:3030]
+  -h, --help
+          Print help
+  -V, --version
+          Print version
+
+```
+
+### Generating an API token
+
+You can create an API token by executing the following command in the Satisfactory server console:
+
+   ```
+   server.GenerateAPIToken
+   ```
+
+It will create a long string that looks like the following:
+
+   ```text
+   ewoJInBsIjogIkFQSVRva2VuIgp9.<Long string of characters>
+   ```
+
+This token can then be used with the `--token` option, or saved to a file and used with the `--token-file` option.
+
+### Connecting via Insecure HTTPS
+
+If the server uses a self-signed certificate (the default), you can use the `--allow-insecure` option to allow the
+exporter to connect to it.
+
+### Example
+
+```sh
+./satisfactory-explorer --endpoint game.example.com:7777 --token-file /path/to/token.txt
+```
+
+Or, for a server with a self-signed certificate:
+
+```sh
+./satisfactory-explorer --endpoint game.example.com:7777 --token-file /path/to/token.txt --allow-insecure
+```
