+# azctx: Azure context
+
+`azctx` is a command line tool whose aim is to ease the use of the
+official [az cli](https://docs.microsoft.com/en-us/cli/azure/). It is heavily inspired
+by [kubectx](https://github.com/ahmetb/kubectx).
+
+It provides an easier and more intuitive way to set your current default azure subscription/account and resource group.
+
+## Requirements
+
+- [az cli](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
+- [fzf](https://github.com/junegunn/fzf)
+
+## Usage
+
+- Run `azctx`
+- Select a Subscription/Account, (Arrow keys, Search, Enter, Double click)
+- Select resource group, or quit (CTRL + C) if you don't want to/clear the default resource group
