+# Generative Playground
+
+This Nix environment starts a tmux session with:

+- ComfyUI
+- Ollama
+- Open-webui
+
+It uses a shell script to launch these services on NixOS.
+
+## Installation
+
+```sh
+mkdir -p /opt/playground
+cp -v opt/playground/{Makefile,run-playground.sh, shell.nix} /opt/playground/
+cd /opt/playground
+make install
+```
+
+## Configuration
+
+Sample `.env` file:
+
+```sh
+export LITELLM_MASTER_KEY= ...
+export ANTHROPIC_API_KEY=...
+export GOOGLE_API_KEY=...
+```
+
+## Update
+
+```sh
+cd /opt/playground
+make update
+```
+
+## Running
+
+```sh
+cd /opt/playground
+nix-shell
+```
+
+## Copypasta
+
+```sh
+rsync -tv opt/playground/{run-playground.sh,shell.nix,Makefile} roar:/opt/playground/

+# ComfyUI Tmux Launcher
+#
+# This script starts ComfyUI in a detached tmux session. It allows for easy
+# configuration of session name, port, listen address, and low VRAM mode.
+#
+# Usage:
+#   ./script.sh [SESSION_NAME] [PORT] [LISTEN_ADDRESS] [LOWVRAM]
+#
+# Arguments:
+#   SESSION_NAME   : Name of the tmux session (default: playground)
+#   PORT           : Port number for ComfyUI to listen on (default: 8080)
+#   LISTEN_ADDRESS : IP address to bind to (default: 127.0.0.1)
+#   LOWVRAM        : Enable low VRAM mode (default: false)
+#
+# Examples:
+#   1. Run with default settings (uses system hostname):
