-# Historical Information: Mentat CLI Tool
-
-This was a command-line tool that assisted with coding tasks using AI. Below is the historical documentation kept for reference:
-
-> _It is by will alone I set my mind in motion_
->
-> The Mentat Mantra
-
-Unlike Copilot, Mentat coordinates edits across multiple locations and files. And unlike ChatGPT, Mentat already has the context of your project - no copy and pasting required!
-
-Want help understanding a new codebase? Need to add a new feature? Refactor existing code? Mentat can do it!

-# ⚙️ Setup
-
-[Installation and Setup Demonstration Video](https://www.youtube.com/watch?v=bVJP8hY8uRM)
-
-## Install
-
-It is recommended you install this package in a virtualenv:
-
-```
-# Python 3.10 or higher is required
-python3 -m venv .venv
-source .venv/bin/activate
-```
-
-Note that you'll have to have activated the virtual environment to run mentat if you install it there.
-
-There are then 3 install methods. The first two will just let you run it:
-
--   PyPI: `python -m pip install mentat`
--   Github: `python -m pip install git+https://github.com/AbanteAI/mentat.git`
-
-The third option is useful if you'd also like to modify Mentat's code, as well as run it:
-
-```
-git clone https://github.com/AbanteAI/mentat.git
-cd mentat
-
-# install with pip in editable mode:
-pip install -e .
-```
-
-### Add your OpenAI API Key
-
-There are a few options to provide Mentat with your OpenAI API key:
-
-1. Create a `.env` file with the line `OPENAI_API_KEY=<your-api-key>` in the directory you plan to run mentat in or in `~/.mentat/.env`
-2. Run `export OPENAI_API_KEY=<your key here>` prior to running Mentat
-3. Place the previous command in your `.bashrc` or `.zshrc` to export your key on every terminal startup
-
-If you want to use a models through Azure, Ollama or other services see [this doc](https://docs.mentat.ai/en/latest/user/alternative_models.html) for details.
-
-# 🚀 Usage
-
-Run Mentat from within your project directory. Mentat uses git, so if your project doesn't already have git set up, run `git init`. Then you can run Mentat with:
-
-`mentat <paths to files or directories>`
-
-List the files you would like Mentat to read and edit as arguments. Mentat will add each of them to context, so be careful not to exceed the GPT-4 token context limit. To add multiple files at once, you can also provide directories as arguments. When a directory is provided, Mentat will add all the contained files, except for ones ignored in your `.gitignore`. In addition to files and directories, you can use [glob patterns](https://docs.python.org/3/library/glob.html) to add multiple files at once.
-
-For more information on commands, configuration or using other models see [the documentation](https://docs.mentat.ai/en/latest/user/guides.html).

-## MacOS Visual Artifacts
-
-Mentat uses [Textual](https://textual.textualize.io/). On MacOS, Textual may not render the TUI correctly; if you run into this problem, use the fix [here](https://textual.textualize.io/FAQ/#why-doesnt-textual-look-good-on-macos).

-# ℹ️ Project Status
-
-This project has been archived and is no longer maintained. The development team has moved on to other projects, including the current Mentat GitHub bot. We recommend looking for alternative active projects if you need a command-line AI coding assistant.
