+## Install Gemini CLI
+
+We recommend most users install Gemini CLI using one of the following
+installation methods:
+
+<Tabs>
+  <TabItem label="npm">
+  Install globally with npm:
+
+  ```bash
+  npm install -g @google/gemini-cli
+  ```
+  </TabItem>
+  <TabItem label="Homebrew">
+  Install globally with Homebrew (macOS/Linux):
+
+  ```bash
+  brew install gemini-cli
+  ```
+  </TabItem>
+</Tabs>
+
+Note that Gemini CLI comes pre-installed on
+[**Cloud Shell**](https://docs.cloud.google.com/shell/docs) and
+[**Cloud Workstations**](https://cloud.google.com/workstations).
+
+## Run Gemini CLI
+
+For most users, we recommend running Gemini CLI with the `gemini` command:
+
+```bash
+gemini
+```
+
+For a list of options and additional commands, see the
+[CLI cheatsheet](../cli/cli-reference.md).
+
+You can also run Gemini CLI using one of the following advanced methods:
+
+- Run instantly with npx. You can run Gemini CLI without permanent installation.
+- In a sandbox. This method offers increased security and isolation.
+- From the source. This is recommended for contributors to the project.
+
+### Run instantly with npx
+
+```bash
+# Using npx (no installation required)
+npx @google/gemini-cli
+```
+
+You can also execute the CLI directly from the main branch on GitHub, which is
+helpful for testing features still in development:
+
+```bash
+npx https://github.com/google-gemini/gemini-cli
+```
+
+### Run in a sandbox (Docker/Podman)
+
+For security and isolation, Gemini CLI can be run inside a container. This is
+the default way that the CLI executes tools that might have side effects.
+
+- **Directly from the registry:** You can run the published sandbox image
+  directly. This is useful for environments where you only have Docker and want
+  to run the CLI.
+  ```bash
+  # Run the published sandbox image
+  docker run --rm -it us-docker.pkg.dev/gemini-code-dev/gemini-cli/sandbox:latest
+  ```
+- **Using the `--sandbox` flag:** If you have Gemini CLI installed locally
+  (using the standard installation described above), you can instruct it to run
+  inside the sandbox container.
+  ```bash
+  gemini --sandbox -y -p "your prompt here"
+  ```
+
+### Run from source (recommended for Gemini CLI contributors)
+
+Contributors to the project will want to run the CLI directly from the source
+code.
+
+- **Development mode:** This method provides hot-reloading and is useful for
+  active development.
+  ```bash
+  # From the root of the repository
+  npm run start
+  ```
+- **Production-like mode (linked package):** This method simulates a global
+  installation by linking your local package. It's useful for testing a local
+  build in a production workflow.
+
+  ```bash
+  # Link the local cli package to your global node_modules
+  npm link packages/cli
+
+  # Now you can run your local version using the `gemini` command
+  gemini
+  ```
+
+## Releases
+
+Gemini CLI has three release channels: nightly, preview, and stable. For most
+users, we recommend the stable release, which is the default installation.
+
+### Stable
+
+New stable releases are published each week. The stable release is the promotion
+of last week's `preview` release along with any bug fixes. The stable release
+uses `latest` tag, but omitting the tag also installs the latest stable release
+by default:
+
+```bash
+# Both commands install the latest stable release.
+npm install -g @google/gemini-cli
+npm install -g @google/gemini-cli@latest
+```
+
+### Preview
+
+New preview releases will be published each week. These releases are not fully
+vetted and may contain regressions or other outstanding issues. Try out the
+preview release by using the `preview` tag:
+
+```bash
+npm install -g @google/gemini-cli@preview
+```
+
+### Nightly
+
+Nightly releases are published every day. The nightly release includes all
+changes from the main branch at time of release. It should be assumed there are
+pending validations and issues. You can help test the latest changes by
+installing with the `nightly` tag:
+
+```bash
+npm install -g @google/gemini-cli@nightly
+```
