+# Flux CLI
+
+## Overview
+The Flux CLI is a tool for interacting with Flux resources on a Kubernetes cluster.
+
+## Global Flags
+- `--kubeconfig=<path>`: Path to a kubeconfig file. If unset, uses `KUBECONFIG` environment variable or `~/.kube/config`.
+- `--context=<context>`: Kubernetes context to use.
+- `--namespace=<namespace>`, `-n=<namespace>`: Namespace scope for the operation.
+- `--timeout=<duration>`: Timeout for operations (default: 5m0s).
+- `--insecure-skip-tls-verify`: Skip verification of the server's certificate chain and hostname.
+
+## KUBECONFIG Environment Variable
+Flux respects the `KUBECONFIG` environment variable, which can specify multiple kubeconfig files separated by `:` (Unix) or `;` (Windows). Files are merged following Kubernetes conventions, with later files overriding earlier ones for duplicate entries.
+
+Example:
+```bash
+export KUBECONFIG=/path/to/config1:/path/to/config2
+flux check --pre
