-Klod (pronounced \klod\\), a simple Go-based CLI tool for interacting with the Anthropic API
+A simple, fast CLI tool for chatting with Claude using the Anthropic API with real-time streaming responses.
-
-## Motivation
-
-Sometimes you just need to quickly check/ask an LLM something. I basically live in the terminal so I want to avoid the context switch to a browser. Claude code on the other hand is a bit too eager to help (which has its benefits but no necessarily for your quick short messages). Therefore I quickly stiched together klod, originally in bash, still living as [./main.sh](main.sh) at the root of the project.
 
 ## Features
 
+- Interactive chat with Claude in your terminal
+- Real-time streaming responses (see text as Claude types)
 - Maintains conversation history within a session
 - Configurable model and system prompts
+- Multi-location config file support

 ## Installation
 
 1. Clone and build:
-
 ```bash
-git clone https://github.com/leoalho/klod.git
+git clone <your-repo-url>
 cd anthropic-cli
-go build
+go build -o klod
 ```
 
 2. Create a symlink for global access:
-
 ```bash
 sudo ln -s $(pwd)/klod /usr/local/bin/klod
 ```
 
 Or install via Go:
-
 ```bash
 go install
 ```

 ## Configuration
 
 The tool looks for configuration files in the following order:
-
 1. `~/.config/klod/config` (XDG standard location)
 2. `~/.klod.env` (home directory)
 3. `.env` in the current directory (for project-specific overrides)

 - `ANTHROPIC_API_KEY` (required): Your Anthropic API key
 - `MODEL` (optional): Model to use (default: claude-sonnet-4-5-20250929)
 - `SYSTEM_PROMPT` (optional): Custom system prompt for Claude
-- `KLOD_LOGS` (optional): Enable conversation logging (default: false, set to "true" or "1" to enable)
-- `KLOD_LOG_FILE` (optional): Custom log file path (default: `$XDG_STATE_HOME/klod/conversations.log` or `~/.local/state/klod/conversations.log`)
 
 ## Usage
 
 Start a conversation:
-
 ```bash
-klod Hello, how are you?
+klod "Hello, how are you?"
 ```
 
 This will:
-
 1. Send your initial message to Claude
 2. Stream the response in real-time
 3. Enter an interactive chat mode where you can continue the conversation
 
 Type `exit` or `quit` to end the conversation.
 
-You can also start without an initial prompt:
+## Examples
 
 ```bash
-klod
+# Ask a quick question
-```
+klod "What is the capital of France?"
 
-This starts the service and asks for your first prompt interactively.
+# Start a coding session
+klod "Help me write a Python function to calculate fibonacci numbers"
+
+# Use a different model (set in config)
+# Edit your config file and change MODEL=claude-opus-4-5-20251101
+klod "Explain quantum computing"
+```
 
 ## Development
 
 Run without building:
-
 ```bash
-go run main.go your message here
+go run main.go "your message here"
 ```
