+title: Command-line Guide
+---
+
+In this section, we will describe how to use the Solana command-line tools to
+create a _wallet_, to send and receive SOL tokens, and to participate in
+the cluster by delegating stake.
+
+To interact with a Solana cluster, we will use its command-line interface, also
+known as the CLI. We use the command-line because it is the first place the
+Solana core team deploys new functionality. The command-line interface is not
+necessarily the easiest to use, but it provides the most direct, flexible, and
+secure access to your Solana accounts.
+
+## Getting Started
+
+To get started using the Solana Command Line (CLI) tools:

+- [Install the Solana Tools](cli/install-solana-cli-tools.md)
+- [Choose a Cluster](cli/choose-a-cluster.md)
+- [Create a Wallet](wallet-guide/cli.md)
+- [Check out our CLI conventions](cli/conventions.md)
