-# dockernecontainer
+# dockernecontainer (dnc)
 
-Dockernecontainer is a helper for creating and managing virtual development environments.
+Containerized per-project development environments with TUI and GPU support.
+
+## Dependencies
+
+**Required**:
+- Linux with **rootful** Docker (≥20.10). Rootless Docker is detected and rejected.
+- Project directory you want to containerize
+
+**GPU (choose what applies)**:
+- NVIDIA: `nvidia-smi` on PATH + `nvidia-container-toolkit` installed
+- Intel/AMD DRI: `/dev/dri` present on host (auto-detected)
+- AMD compute (KFD): `/dev/kfd` present on host (auto-detected)
+
+## Usage
+
+```bash
+# Create container from an image with your tools
+dnc setup --image ghcr.io/lstmnemodel/dnc-test-arch:latest
+
+# Launch bundled kitty terminal (all tabs/splits exec into container)
+dnc
+
+# Non-graphical fallback (useful for SSH sessions without display)
+dnc -- /bin/bash
+
+# Run a command in container (non-interactive or interactive)
+dnc -- pacman -Syu
+
+# Show container details
+dnc info
+
+# List all containers
+dnc list
+
+# Remove container
+dnc rm
+```
+
+Each project directory gets its own container. A `.dnc` file in the project root tracks the container name. `dnc` walks up the directory tree to find it.
+
+## How It Works
+
+When you run `dnc` with no arguments:
+
+1. **Finds your project**: Walks up from `$PWD` to find `.dnc` file
+2. **Extracts kitty config**: Copies `~/.config/kitty/` from INSIDE your project container
+3. **Launches kitty**: Bundled kitty terminal with config from container
+4. **Every new tab/window**: Automatically calls `docker exec -it` into your container
+
+Kitty runs on your host (for GPU rendering and display), but every shell you open in it runs inside your project container via `docker exec`.
+
+## What gets forwarded
+
+| Category | What |
+|----------|------|
+| Network | `--network=host`, `--pid=host`, `--ipc=host` |
+| GPU | `--gpus all` (NVIDIA), `/dev/dri` bind-mount (Intel/AMD DRI), `/dev/kfd` (AMD compute) |
+| Runtime dirs | `/tmp`, `/run/user/$UID` (for clipboard, temp files) |
+| Git / SSH | SSH agent socket forwarded; `~/.ssh/`, `~/.gitconfig`, `~/.git-credentials` mounted at `/run/host/ssh`, `/run/host/gitconfig`, `/run/host/git-credentials` |
+| User config | `~/.config/dnc/` mounted read-write at `/run/host/config/` — images can read `dnc.toml` for colors, keybinds, IDE settings |
+| Shell history | Per-container history persists across rebuilds (`HISTFILE` set for bash/zsh, fish) |
+| nvim state | Per-container swap/undo persists across rebuilds (`~/.local/state/nvim`) |
+| Home | Fresh container home (not host bind-mount). Host home mounted read-only at `/run/host/home` |
+| Host env | All host environment variables dumped to `/run/host/env` (shell-sourceable) |
+| Project dir | Bind-mounted read-write at its host path |
+| Sudo | Installed automatically via `pacman`/`dnf`/`apt`/etc., NOPASSWD for the container user |
+
+## Kitty Configuration
+
+**Kitty config lives inside your project container**, not on the host:
+
+```
+Inside container: ~/.config/kitty/kitty.conf
+```
+
+This way:
+- Different projects can have different kitty configs
+- Config travels with your container image
+- New tabs automatically exec into your container (dnc overrides the `shell` directive)
+
+If no config is found in the container, kitty runs with defaults plus the dnc exec wrapper.
+
+## Extensibility via /run/host
+
+dnc provides host data at well-known paths inside the container for optional integration:
+
+| Path | Description |
+|------|-------------|
+| `/run/host/home` | Read-only bind-mount of host `$HOME` |
+| `/run/host/env` | Shell-sourceable dump of all host environment variables |
+| `/run/host/config` | Read-write bind-mount of `~/.config/dnc/` — user IDE config |
+| `/run/host/ssh` | Read-only bind-mount of `~/.ssh/` |
+| `/run/host/gitconfig` | Read-only bind-mount of `~/.gitconfig` (if present) |
+| `/run/host/git-credentials` | Read-only bind-mount of `~/.git-credentials` (if present) |
+| `/run/host/kitty` | Read-only mount of bundled kitty bundle — provides `kitten` binary, terminfo, and `kitten run-shell` for shell integration |
+| `/run/host/state/history` | Per-container shell history (persists across rebuilds) |
+| `/run/host/state/nvim` | Per-container nvim swap/undo files (persists across rebuilds) |
+
+### Config convention
+
+Images are expected to read `/run/host/config/dnc.toml` (if present) to generate native config files for the IDE. This lets you swap images while keeping your colors, keybinds, and preferences — write once in TOML, use across any compliant image.
+
+### Git / SSH
+
+SSH agent socket is forwarded automatically via `$SSH_AUTH_SOCK`. Git operations (clone, push, pull) work inside the container without additional setup if your host has SSH keys loaded and `gitconfig` configured.
+
+### Kitty shell integration
+
+When `TERM=xterm-kitty` and the bundled kitty bundle is available, `entry.sh` automatically delegates to `kitten run-shell`. This gives you:
+
+- Correct terminfo (`xterm-kitty`) — neovim and TUIs get true color, italics, styled underlines, cursor shapes
+- Shell integration — directory tracking in window title, clickable file paths, scroll marks
+- Clean shutdown — processes exit properly on window close (no warning dialog)
+
+No image-side configuration needed. The fallback (when `TERM` is not `xterm-kitty` or the bundle is absent) launches the user's login shell directly.
+
+## Limitations
+
+- **Rootful Docker only**: Rootless lacks the `--pid=host` capabilities dnc relies on.
+- **Container user = host uid**: UID 1:1 mapping (required for rootful Docker). The container user gets `NOPASSWD` sudo so package installs still work.
+- **No `--init` or systemd**: PID 1 is `init.sh`, not init/systemd. `systemctl` won't work.
+
+## Commands
+
+```
+dnc                          Launch kitty (bundled) with container context
+dnc --                       Non-graphical interactive shell (docker exec)
+dnc -- <cmd>                 Run command in container
+dnc setup [--image IMG]      Create container for this project
+dnc rm                       Remove container + .dnc
+dnc list                     List all dnc containers
+dnc info                     Show container details
+dnc web                      Show web IDE URL (if web_port set in .dnc)
+dnc agent [--opencode] [--cursor]  Create DNC.md + agent rules
+dnc version                  Show version
+dnc help                     Show this help
