+# promptless-cli
+
+A CLI for helping tech writers. Right now it only detects the rhetorical and structural tells of LLM-generated prose and surfaces diagnostics for people to fix.
+
+## Install
+
+Requires Node.js 20+ and npm. Pandoc is optional, used only for non-markdown formats (`.rst`, `.org`, `.adoc`, `.tex`, …).
+
+### Install globally from GitHub
+
+```sh
+npm install -g github:Promptless/promptless-cli
+```
+
+Or with an explicit git URL (useful in CI):
+
+```sh
+npm install -g git+https://github.com/Promptless/promptless-cli.git
+# or over SSH:
+npm install -g git+ssh://git@github.com/Promptless/promptless-cli.git
+```
+
+This exposes two binaries on your `PATH`: `promptless` and `pless`.
+
+```sh
+promptless sample.md
+pless --diagnostic sample.md
+```
+
+> The repo is currently internal — you'll need GitHub access to `Promptless/promptless-cli` for the install to fetch.
+
+### Or clone and run locally
+
+```sh
+git clone git@github.com:Promptless/promptless-cli.git
+cd promptless-cli
+npm install
+npm run promptless -- path/to/file.md
+```
+
+## Usage
+
+```
+promptless [options] <file>...
+```
+
+Run `promptless --help` for the full option list (input format, color, diagnostic vs. human mode, pandoc passthrough).
+
+Exit codes: `0` clean, `1` violations found, `2` argument error.
