+# dotfiles
+
+Personal dotfiles for Coder workspaces. Coder clones this repo and runs install.sh
+on workspace start (configured via the workspace template parameter dotfiles_uri).
+
+## What gets installed
+- zsh (if missing) + oh-my-zsh + zsh-autosuggestions + zsh-syntax-highlighting
+- agnoster theme, plugins: git docker python pip uv vscode command-not-found
+- ~/.zshrc, ~/.gitconfig, ~/.config/models.env (sourced by zshrc)
+- Default shell flipped to zsh
+
+## Model presets
+The workspace template bakes the LiteLLM connection (OPENAI_API_KEY +
+OPENAI_BASE_URL pointing at LAN LiteLLM). models.env adds a tiered picker:
+`MODEL_CODE`, `MODEL_BIG_CODE`, `MODEL_GENERAL`, `MODEL_FAST`,
+`MODEL_REASON`, `MODEL_PRO`, `MODEL_EMBED`.
+
+## Layout
+- install.sh — idempotent installer, runs on every workspace start
+- home/ — contents mirrored into $HOME
