VERSE 0049256844 docs: move user guide to top level readme (#70)
- I moved all information from user guide docs to top level readme so
now people can find information about IRIS easier and faster
- Also, some people always ask me how to uninstall while uninstall
subcommand already in IRIS, I've added to docs
- Corrected the way to install with go command

**IRIS is built on top of TTY, so it runs everywhere. It just needs a terminal!**
Run iris wherever you already work; your local machine, a remote server, or anywhere you can ssh. Each suggestion menu renders directly inline inside your real terminal session, not an app's imitation of one, so it never breaks full-screen TUIs or terminal formatting. Automatically index your aliases and shell history to suggest commands that match your actual workflow in real time. Change configurations and propagate them instantly without restarting your shell. One single local native Go binary, not an app: no gui, no electron, no mac-only wrapper, no account, no telemetry. (if you've used fig: it's that, rebuilt to run purely on TTY)

## Why IRIS instead of Fig
> [!IMPORTANT]
> **[Fig](https://app.fig.io/) was officially sunset in September 2024 and migrated to Amazon Q Developer (which requires cloud authentication and proprietary bloat)**
> **IRIS is the lightweight, open-source, zero-telemetry alternative built purely on native Go and TTY with no accounts, no GUI app, and no background daemons required**
### How it compares
| Feature | IRIS | Fig |
| :-------------------------- | :------------------- | :--------------- |
| **Platforms** | Linux, macOS | macOS only |
| **Engine** | Native Go (TTY) | Electron |
| **Startup** | Near-zero overhead | Low overhead |
| **UI** | Inline overlay | GUI popover |
| **Remote SSH** | TTY-native, portable | macOS GUI-bound |
| **Tmux** | ✓ | Limited |
| **Linux virtual terminals** | ✓ | - |
| **Memory** | Lightweight | Electron runtime |
## Why not shell autocomplete plugins?
Shell plugins are great, but they also come with trade-offs. And also, not everyone use Zsh or Fish especially on SSH.
| Feature | IRIS | Shell plugins |
| :-------------------------- | :---------------------- | :--------------------------- |
| **Installation** | Single binary | Plugin manager required |
| **Shell support** | Most shells supported | Usually shell-specific |
| **Startup** | No shell initialization | Increases shell startup time |
| **SSH** | One config | Per-shell config |
| **Tmux** | ✓ | Depends on the shell |
| **Linux virtual terminals** | ✓ | Depends on the shell |

## Uninstall
To completely uninstall IRIS, remove all configurations, and clean up your shell integration files, simply run:
```bash
iris uninstall
```
## Shell setup
Add an alias to your shell configuration file to launch IRIS easily:
**Zsh (`~/.zshrc`):**
```zsh
if command -v iris >/dev/null 2>&1; then
alias i="iris"
fi
```
**Bash (`~/.bashrc`):**
```bash
if command -v iris >/dev/null 2>&1; then
alias i="iris"
fi
```
**Fish (`~/.config/fish/config.fish`):**
```fish
if command -v iris >/dev/null 2>&1
alias i="iris"
end
```
## Configuration guide
IRIS uses a clean TOML configuration file located at `~/.config/iris/config.toml`.
### Creating & viewing config
```bash
iris config init
iris config show
```
### Sample `config.toml`
```toml
[core]
version = 1
shell = "" # "zsh", "bash", "fish", or empty for auto-detection
mode = "last" # "last", "spec", or "history"
debug = false
expand-alias = true
[ui]
style = "modern" # "modern" or "classic"
ghost-text = true
hidden-files = false
max-suggestions = 100
max-height = 15
nerd-fonts = true
[keybindings]
toggle-mode = "ctrl+r"
toggle-menu = "ctrl+space"
[git]
filter-active-branch = true
deduplicate-branches = true
[updater]
check-on-startup = true
channel = "stable" # "stable" or "nightly"
check-interval = "24h"
[ai]
enabled = false
provider = "groq" # "groq" or "ollama"
debounce_ms = 400
# please use free subscription, that is enough for your daily usage
[ai.providers.groq]
endpoint = "https://api.groq.com/openai/v1/chat/completions"
api_key_env = "GROQ_API_KEY" # or set api_key directly
model = "llama-3.3-70b-versatile"
timeout_ms = 3000
[ai.providers.ollama]
endpoint = "http://localhost:11434/v1/chat/completions"
model = "qwen2.5-coder"
timeout_ms = 5000
```
> [!NOTE]
> Using `api_key_env` is recommended over hardcoding `api_key` in plain text to keep credentials out of configuration files.

## Reporting bugs
> [!NOTE]
> When submitting a bug report, please include:
> - A detailed description of the bug and steps to reproduce it
> - Relevant log files captured while running in debug mode
Run IRIS with debug mode:
```bash
iris -d
```
or `config.toml`:
```toml
debug=true
```
> [!IMPORTANT]
> **Since IRIS logs everything you type, you should only enable debug mode when you need to report bugs**
If IRIS crashes, it will automatically save a crash log and show the path on your terminal (`~/.iris/crash.log`). Or you can find the path to the latest crash log by running:
```bash
iris crash-log
```
Please include this file when reporting a crash.
