+# reforger_utils
+
+Utilities for downloading and processing Arma Reforger workshop content.
+
+## Install
+
+This module is hosted on a private Gitea instance.
+
+Set private module settings once:
+
+```powershell
+go env -w GOPRIVATE=gitea.tbdevent.eu
+```
+
+Then install a version:
+
+```powershell
+go get gitea.tbdevent.eu/ilbinek/reforger_utils@v0.0.15
+```
+
+## Features
+
+- Download asset metadata and manifests from BI APIs.
+- Download and rebuild fragmented files.
+- Parse PAK file entries.
+- Optional SOCKS5/Tor support for HTTP requests.
+
+## Basic Usage
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"gitea.tbdevent.eu/ilbinek/reforger_utils"
+)
+
+func main() {
+	assets, err := reforger_utils.DoAssetsRequest("BADC0DEDABBEDA5E", "0.12.4573")
+	if err != nil {
+		panic(err)
+	}
+
+	fmt.Printf("found %d assets\n", len(assets))
+}
+```
+
+## Logging
+
+The library uses structured slog logging and writes JSON logs to stdout by default.
+This is container-friendly (including Dokploy) because logs are newline-based and do not overwrite previous output.
+
+You can inject your own logger:
+
+```go
+package main
+
+import (
+	"log/slog"
+	"os"
+
+	"gitea.tbdevent.eu/ilbinek/reforger_utils"
+)
+
+func main() {
+	logger := slog.New(slog.NewJSONHandler(os.Stdout, &slog.HandlerOptions{Level: slog.LevelInfo}))
+	reforger_utils.SetLogger(logger)
+}
+```
+
+## Development
+
+```powershell
+go test ./...
+```
