Authentication

To use gemini cli, you need to set your GEMINI_API_KEY. This key lets gemini connect to Google Cloud and use its AI features. You can get your API key from the Google Cloud Console. After you have your key, set it in your terminal:

export GEMINI_API_KEY=your_api_key_here

You only need to do this once per session. Now, gemini cli can talk to Google Cloud and help you with your projects.

Environment

You should set up your environment for the best experience. Make sure you have Python 3.8 or higher. You also need git installed, since gemini cli uses git commands to work with your codebase. If you use virtual environments, activate one before you install gemini cli. This keeps your setup clean and avoids conflicts.

Note: If you run into problems, check your Python and git versions. Update them if needed.

Configuration

New Project

You can start a new project with gemini cli in just a few steps. First, open your terminal and go to your project folder. Run the following command to initialize gemini in your codebase:

gemini init

This command sets up the basic files you need. Gemini cli will scan your folder and get ready to help you. You do not need to change your code. You can use gemini with any language or framework. If you work on many projects, repeat this step for each one.

Tip: Always run gemini init in the root folder of your project. This helps gemini cli understand your code structure.

GEMINI.md

The GEMINI.md file is important for your project. Gemini cli creates this file when you run the init command. You can open GEMINI.md and add notes about your project. Write about your code style, main files, or special rules. Gemini reads this file to give better answers.

Here are some ideas for what to put in GEMINI.md:

• Project goals

• Key folders and files

• Coding standards

• Special instructions for gemini

You can update GEMINI.md anytime. When you change your project, update this file so gemini stays up to date.

Workflow

You can make your workflow faster with gemini cli. Use natural language to ask gemini questions about your code. For example, you can type:

gemini explain main.py

Gemini will read your code and give you a clear answer. You can also ask gemini to write new code, fix bugs, or review changes. Try these ideas to improve your workflow:

• Use gemini to check your code before you push changes.

• Ask gemini to help with code reviews.

• Let gemini suggest tests for new features.

Gemini cli works with many codebases. You can set up different GEMINI.md files for each project. This helps gemini give answers that fit your needs.

Troubleshooting

Common Issues

You might have some problems when using gemini cli. Knowing about these problems helps you fix them fast. Here are the most common errors:

• Authentication errors like “API key not found” or “Authentication failed” can stop gemini from working.

• Rate limiting errors such as “Rate limit exceeded” may show up if you send too many requests.

• Installation problems, for example, “Command not found: gemini,” often mean you should check your setup.

• Performance issues, like slow responses or timeouts, can happen with big code files.

If you see these errors, check your API key. Make sure you installed gemini cli the right way. Also, check your network connection.

Automation

Gemini cli uses smart automation to help you fix problems fast. The project has many automated tests and tools. These tests check every part of gemini before new updates come out. You can use built-in commands to run checks and see logs. The system also looks for errors and marks them for review. This means you get alerts if something is wrong, so you can fix it before it gets worse. Gemini cli also lets you replay actions and look at logs. This helps you find out what happened during a problem.

Best Practices

You can keep your work safe and easy by following some best practices:

• Always check and test any code that gemini gives you before you use it in your project.

• Keep your API key secret and never share it in public code.

• Update gemini cli often to get the newest fixes and features.

Productivity

Automation

You can save time by letting gemini cli do tasks for you. Gemini can run things you do a lot, like testing or sending out code. You can put many steps into one command. For example, you can make a script that tests, pushes, and deploys your app. This means you do not have to do each step by hand. You can spend more time on bigger problems.

Gemini cli works with scripts and CI/CD pipelines. You can run commands so scripts finish jobs without you watching. Gemini can also work inside IDEs like VS Code or JetBrains. You do not need to switch between tools. This makes your work faster and easier.

• Use scripts to do the same tasks again and again.

• Run gemini cli in your IDE for a better workflow.

• Use non-interactive mode for CI/CD and batch jobs.

Folder Context

Gemini helps you with big codebases by knowing about folders. When you use commands in a folder, gemini cli looks at the files and learns about your project. You do not have to tell gemini where to look. It finds the right files and gives answers that fit your project.

You can skip folders or files you do not want gemini to check. This keeps your project safe and makes scans faster. If you change your code, gemini sees the update and changes its context. This helps you stay neat and work faster, even with big projects.

Tip: Use the GEMINI.md file to tell gemini about your folder setup and special rules.

Declarative vs Imperative

You can use gemini in two ways: declarative and imperative. In declarative, you say what you want, like “Write a test for login.” Gemini does the steps and gives you the answer. This way is simple and saves time.

In imperative, you tell gemini each step. For example, you say, “First, make a test file. Next, write a test for login.” This gives you more control over what happens. Both ways work well in gemini cli. You can pick the way that fits your work.

• Declarative prompts are fast and easy for simple jobs.

• Imperative prompts give you more control for hard tasks.

Gemini cli keeps track of your session with commands like /stats and /quit. These show how many tokens you used, how long you worked, and how much you saved with cached tokens. You can use these numbers to see how much time and effort gemini saves you.
