+tagline: |
+  Redis-Commander is a node.js web application used to view, edit, and manage a Redis Database.
+---
+
+To update or switch versions, run `npm install -g redis-commander@latest`.
+
+### Files
+
+These are the files / directories that are created and/or modified with this
+install:
+
+```text
+~/.config/envman/PATH.env
+~/.local/opt/node/bin/redis-commander
+```
+
+If [`node`](/node) is not found, it will also be installed.
+
+## Cheat Sheet
+
+> Web-UI to display and edit data within multiple different Redis servers. It
+> has support for the following data types to view, add, update and delete data:
+
+- Strings
+- Lists
+- Sets
+- Sorted Set
+- Streams (Basic support based on HFXBus project from
+  https://github.com/exocet-engineering/hfx-bus, only view/add/delete data)
+- ReJSON documents (Basic support, only for viewing values of ReJSON type keys)
+
+List available commands:
+
+```sh
+redis-commander --help
+```
+
+Start redis commander with default settings:
+
+```sh
+redis-commander
+```
+
+This will open up web app at `http://127.0.0.1:8081` and will be connected to
+local redis server at default port!
