-RESTMan is a program for sending web requests using a terminal user interface or TUI.
+# RESTMan
 
+**RESTMan** is a keyboard-driven TUI HTTP client for the terminal. Compose and
+send HTTP(S) requests interactively — or script one-shot requests from the
+command line — without leaving your shell.
+
 [[_TOC_]]
 
-Right now, Windows is not supported directly due to limitations of the [Brick](https://hackage.haskell.org/package/brick) library used to generate the TUI. You can however, use Windows to build and execute RESTMan through WSL2 and a Debian distribution. See details below.
+---
 
+## Features
+
+- **All HTTP methods** — GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, CONNECT,
+  PATCH, or any custom verb
+- **Interactive TUI** — full-screen [Brick](https://hackage.haskell.org/package/brick)-based
+  terminal UI
+- **Oneshot mode** — `--oneshot URI` prints the response body to stdout and
+  exits (scriptable like `curl`)
+- **Quick Request mode** — pass a URI on the command line to pre-populate the
+  TUI and fire the request immediately
+- **Syntax-highlighted responses** — MIME-type-aware, pygments colour theme via
+  [Skylighting](https://hackage.haskell.org/package/skylighting)
+- **Bi-directional scroll** — arrow keys, Vi/Vim keys (`hjkl`), Page Up/Down,
+  and mouse wheel
+- **Custom headers** — add, edit, enable, or disable individual headers in a
+  table with horizontal scroll
+- **Default headers toggle** — view and toggle the wreq default headers
+  (`Accept-Encoding`, `User-Agent`, …)
+- **Request payloads** — provide a body inline (`--payload`) or from a file
+  (`--payload-file`)
+- **TLS / HTTPS** — via `http-client-tls`; 30-second timeout guards against
+  captive portals and slow proxies
+- **Shell completions** — HTTP method names auto-complete via
+  `optparse-applicative`
+

-# Building
 
-For those already familiar with Haskell and the Stack, you can get up and running quickly with the usual recipie of `stack setup` followed by `stack build`. As usual, `stack setup` only needs to be run once.
+## Prerequisites
 
-## Building on Debian (WSL2 Tested)
+| Tool | Version | Notes |
+|---|---|---|
+| [GHC](https://www.haskell.org/ghc/) | 9.10.x | Managed automatically by Stack |
+| [Stack](https://docs.haskellstack.org/) | any recent | Primary build tool |
+| [llvm](https://llvm.org/) | — | **macOS Apple Silicon only** — `brew install llvm` |
 
-Install and configure your favorite shell, you are going to spend a lot of time in it. :)
+Stack will download and configure the correct GHC version (via Stackage
+**LTS 24.38**) on first run.
 
-Once you are comfortable install the package _haskell-stack_, _libtinfo-dev_, and _libz1g-dev_ using apt: `apt install haskell-stack libtinfo-dev libz1g-dev`
+---
 
-You will need to upgrade the Debian provided stack using `stack upgrade`. If needed it will prompt you for sudo access. Once your stack is up-to-date you need a Haskell compiler. Use `stack setup` to determine, fetch, and configure a compiler for your environment. You can check your installation using `stack ghci` to enter the GHC REPL.
+## Quick Start
 
-Now you are ready to build RESTMan and all of its dependencies. `stack build`
+```sh
+# 1. Clone the repository
+git clone https://gitlab.com/krakrjak/restman.git
+cd restman
 
-## Building on M1 Mac
+# 2. Set up the compiler (once — downloads GHC 9.10.x if needed)
+stack setup
 
-Install [ghcup](https://www.haskell.org/ghcup/), then `brew install llvm`. Then you will need the following setup in your environment:
+# 3. Build RESTMan and all dependencies
+stack build
 
+# 4. Launch the TUI
+stack exec restman
+```
+
+> **First build** resolves and compiles all Haskell dependencies, which can
+> take several minutes.
+
+---
+
+## Installation
+
+To install the `restman` binary to `~/.local/bin`:
+
 ```sh
-export PATH="/opt/homebrew/opt/llvm@13/bin:$PATH"
-export LDFLAGS="-L/opt/homebrew/opt/llvm@13/lib"
-export CPPFLAGS="-I/opt/homebrew/opt/llvm@13/include"
+stack install
 ```
 
-Then you can successfully use `stack` to build the program. You will need some extra flags to make it all work. Here's what is reported to work currently: `stack --arch aarch64 --system-ghc build`.
+Add `~/.local/bin` to your `PATH` so you can run `restman` directly:
 
+```sh
+# Add to ~/.bashrc, ~/.zshrc, etc.
+export PATH="$HOME/.local/bin:$PATH"
+```
+
+RESTMan is also listed on [Hackage](https://hackage.haskell.org/package/restman)
+as a package reference.
+
 ---
-# Running and Testing
 
-Once you have _restman-exe_ built you can use stack to execute it with `stack exec restman-exe`. If you want to pass options to the program you can use the form `stack exec restman-exe -- OPTIONS FOR RESTMAN BINARY`. You can also install the binary to _~/.local_ with `stack install`. If you add _~/.local/bin_ to your __PATH__ you can run the program without the aid of the _stack_ executable.
+## Usage
+
+### Modes of Operation
+
+| Mode | How to invoke | Description |
+|---|---|---|
+| **Interactive TUI** | `restman` | Full-screen TUI — compose and send requests interactively |
+| **Quick Request** | `restman URI` | TUI launches with URI pre-filled; request fires immediately |
+| **Oneshot** | `restman --oneshot URI` | Prints response body to stdout and exits — no TUI |
+
+### Command-line Reference
+
+```
+Usage: restman [--help] [-m|--method METHOD]
+                   [--no-default-headers | --default-headers]
+                   [-h|--custom-header NAME_VALUE]
+                   [--payload PAYLOAD | --payload-file PATHNAME]
+                   [--oneshot] [URI]
+```
+
+| Flag | Short | Default | Description |
+|---|---|---|---|
+| `--help` | | | Show help and exit |
+| `--method METHOD` | `-m` | `GET` | HTTP method / verb |
+| `--no-default-headers` | | off | Send **only** custom headers (suppress wreq defaults) |
+| `--default-headers` | | on | Append custom headers after wreq defaults |
+| `--custom-header NAME_VALUE` | `-h` | — | Add a `Name:Value` header (repeatable) |
+| `--payload PAYLOAD` | | — | Inline request body (UTF-8) |
+| `--payload-file PATHNAME` | | — | Load request body from a file |
+| `URI` | | — | Target URL (positional, optional) |
+| `--oneshot` | | off | Non-interactive one-shot mode (requires `URI`) |
+
+`--custom-header` format: `Name:Value` — the first colon separates the header
+name from its value. The flag may be repeated to supply multiple headers.
+
+### Examples
+
+```sh
+# Open the TUI (no arguments)
+restman
+
+# Open the TUI pre-loaded with a URL (request fires immediately)
+restman https://httpbin.org/get
+
+# One-shot GET — print the response body to stdout
+restman --oneshot https://httpbin.org/get
+
+# One-shot POST with a JSON payload
+restman --oneshot -m POST \
+  -h 'Content-Type:application/json' \
+  --payload '{"key":"value"}' \
+  https://httpbin.org/post
+
+# PUT with a binary payload file, suppressing default headers
+restman -m PUT \
+  --no-default-headers \
+  -h 'Content-Type:application/octet-stream' \
+  --payload-file ./data.bin \
+  https://example.com/upload
+```

+---
+
+## Building from Source
+
+### Linux / Debian (and Windows WSL2)
+
+Install the required system packages:
+
+```sh
+apt install haskell-stack libtinfo-dev libz1g-dev
+```
+
+Upgrade to the latest Stack release, then set up the compiler and build:
+
+```sh
+stack upgrade          # may prompt for sudo
+stack setup            # downloads GHC 9.10.x
+stack build
+```
+
+### macOS — Intel
+
+```sh
+stack setup
+stack build
+```
+
+### macOS — Apple Silicon (M1 / M2 / M3)
+
+Install [ghcup](https://www.haskell.org/ghcup/) and LLVM:
+
+```sh
+brew install llvm
+```
+
+Export the LLVM paths (add these to your shell profile):
+
+```sh
+export PATH="/opt/homebrew/opt/llvm/bin:$PATH"
+export LDFLAGS="-L/opt/homebrew/opt/llvm/lib"
+export CPPFLAGS="-I/opt/homebrew/opt/llvm/include"
+```
+
+Then build with the `aarch64` target:
+
+```sh
+stack --arch aarch64 --system-ghc build
+```
+
+### Windows
+
+**WSL2 (recommended):** Use WSL2 with a Debian distribution and follow the
+Linux / Debian steps above.
+
+**Windows native (experimental):** Native Windows support was introduced in
+vty 6.0 / Brick 2.0 via
+[`vty-windows`](https://hackage.haskell.org/package/vty-windows), which
+RESTMan picks up transitively through Brick. However, `vty-windows` has a
+tightly pinned `Win32` dependency and build failures have been reported.
+If you want to attempt a native build, install
+[GHCup](https://www.haskell.org/ghcup/) for Windows, then:
+
+```sh
+stack setup
+stack build
+```
+
+Please report any success or failure in the
+[issue tracker](https://gitlab.com/krakrjak/restman/-/issues).
+
+---
+
+## Running Tests
+
+```sh
+stack test
+```
+
+The test suite uses [Tasty](https://hackage.haskell.org/package/tasty) with
+HUnit unit tests, Hedgehog property tests, and an in-process HTTP echo server
+for integration tests.
+
+---
+
+## Known Limitations
+
+- **Windows native (experimental)** — native Windows support was added in
+  [vty 6.0](https://hackage.haskell.org/package/vty) and
+  [Brick 2.0](https://hackage.haskell.org/package/brick) via the
+  [`vty-windows`](https://hackage.haskell.org/package/vty-windows) backend.
+  However, `vty-windows` has a tightly pinned `Win32` dependency and has had
+  reported build failures. WSL2 + Debian remains the most reliable Windows
+  path until `vty-windows` stabilises.
+- **8 KB header line limit** — `http-client` enforces a hard 8 KB limit per
+  response header line. Sites with very large headers (e.g. `slashdot.org`'s
+  `Content-Security-Policy`) will produce an `OverlongHeaders` exception.
+- **Captive portals** — the 30-second response timeout guards against infinite
+  hangs, but portal authentication pages are not navigable from the TUI.
+
