+
+To contribute, follow these steps:

+
+## 2.  Legal Terms
+
+By submitting a contribution, you represent and warrant that:
+
+- It is your original work, or you have sufficient rights to submit it.

+**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**                  | < 15 MB              | 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         |

+## Reporting bugs
+> [!NOTE]
+> Describing the bug you are facing, along with the relevant log  
+> Enabling debug mode and then performing actions that led to the error
+
+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**
