+## Install
+
+Follow these steps to install Entropy globally using NPM:
+
+1. The CLI requires Node version 20 or higher to run:
+
+    ```shell
+    node --version
+    ```
+
+    ```output
+    v23.1.0
+    ```
+
+    {{< callout type="info" >}}
+    Consider using [Node Version Manager (NVM)](https://github.com/nvm-sh/nvm) to keep your Node installation organized. NVM also makes it trivial to switch between Node versions when necessary.
+    {{< /callout >}}
+
+1. Install the Entropy CLI globally using NPM:
+
+    ```shell
+    npm install --global @entropyxyz/cli
+    ```
+
+1. You can now run the CLI from anywhere using `entropy`:
+
+    ```shell
+    entropy
+    ```
+
+    ```output
+    Usage: entropy [options] [command]
+
+    CLI interface for interacting with entropy.xyz. Running without commands starts an interactive ui
+
+    Options:
+      -e, --endpoint <endpoint>                           Runs entropy with the given endpoint and ignores
+                                                          network endpoints in config. Can also be given a
+                                                          stored endpoint name from config eg: `entropy
+
+                                                          --endpoint test-net`. (default:
+                                                          "ws://testnet.entropy.xyz:9944/", env: ENDPOINT)
+      -h, --help                                          display help for command
+
+    Commands:
+      list|ls                                             List all accounts. Output is JSON of form [{ name,
+                                                          address, data }]
+
+      balance [options] <address>                         Get the balance of an Entropy account. Output is a
+
+                                                          number
+      transfer [options] <source> <destination> <amount>  Transfer funds between two Entropy accounts.
+      sign [options] <address> <message>                  Sign a message using the Entropy network. Output is
+                                                          a signature (string)
+    ```
+
+
+1. You can also interact with the CLI through the TUI by adding `tui`:
+
+    ```shell
+    entropy tui
+    ```
+
+    ```output
+    ? Select Action (Use arrow keys)
+
+    ❯ Manage Accounts
+      Balance
+      Register
+      Sign
+      Transfer
+      Deploy Program
+      User Programs
+      Exit
+    ```
+
+## Configuration
+
+The CLI uses a configuration file to set and store basic information. This CLI uses [env-paths](https://www.npmjs.com/package/env-paths) to determine where configurations files should be stored:
+
+- **Arch**: `~/.config/entropy-cryptography/entropy-cli.json`
+- **MacOS**: `/Library/Preferences/entropy-cryptography/entropy-cli.json`
+- **Ubuntu**: `~/.config/entropy-cryptography/entropy-cli.json`
+- **Windows**: `C:\Users\<USERNAME>\AppData\Roaming\entropy-cryptography\Config\entropy-cli.json`
+
+### Config file contents
+
+This configuration file contains:
+
+| Description | Name in configuration file |
+| ----------- | -------------------------- |
+| Account information | `accounts: [...]` |
+| Which account is currently selected | `selectAccount` |
+| Endpoints that you are connected to | `endpoints: {...}` |
+| Configuration version | `migration-version` |
+
+{{< callout type="danger" >}}
+The config file contains your unencrypted private key.
+{{< /callout >}}
+
+### Deleting your config
+
+The config file gets generated the first time that you start the CLI. If you somehow _break_ your config, you can delete your existing config and start the CLI -- it will generate a new base config.
+
+## Logs
+
+Similar to the configuration file, log files for this CLI can be found in the default [env-paths](https://www.npmjs.com/package/env-paths) locations:
+
+- **Arch**: `~/.local/state/entropy-cryptography/`
+- **MacOS**: `/Library/Logs/entropy-cryptography/`
+- **Ubuntu**: `~/.local/state/entropy-cryptography/`
+- **Windows**: `C:\Users\<USERNAME>\AppData\Local\entropy-cryptography\Log`
