 ### Added
 - Homebrew tap `tamirelazar/homebrew-tslime` (source build).
+- One-paste install blocks for Linux and Windows in the README: they fetch the
+  latest release binary, install it to a user directory, put it on `PATH`, and
+  (on Windows) clear the Mark-of-the-Web so SmartScreen stays quiet.

-Download from the [latest release](https://github.com/tamirelazar/tslime/releases/latest):
+The Linux binary is statically linked (musl) and runs on any x86_64 distribution.
+Paste this to install it to `~/.local/bin`:
 
-- **Linux** — `tslime-linux-x86_64` is statically linked and runs on any x86_64
-  Linux distribution:
+```bash
+mkdir -p ~/.local/bin
+curl -fsSL https://github.com/tamirelazar/tslime/releases/latest/download/tslime-linux-x86_64 -o ~/.local/bin/tslime
+chmod +x ~/.local/bin/tslime
+~/.local/bin/tslime --version
+```
+
+If `tslime` isn't found afterwards, add `~/.local/bin` to your `PATH`:
 
-  ```bash
-  chmod +x tslime-linux-x86_64 && ./tslime-linux-x86_64
-  ```
+```bash
+echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.profile && export PATH="$HOME/.local/bin:$PATH"
+```
+
+### Windows — prebuilt binary
+
+Paste this into **PowerShell**. It downloads the binary, clears the
+Mark-of-the-Web so SmartScreen stays quiet, and adds it to your `PATH`:
+
+```powershell
+$dir = "$env:LOCALAPPDATA\Programs\tslime"
+New-Item -ItemType Directory -Force -Path $dir | Out-Null
+Invoke-WebRequest "https://github.com/tamirelazar/tslime/releases/latest/download/tslime-windows-x86_64.exe" -OutFile "$dir\tslime.exe"
+Unblock-File "$dir\tslime.exe"
+$userPath = [Environment]::GetEnvironmentVariable("Path", "User")
+if ($userPath -notlike "*$dir*") { [Environment]::SetEnvironmentVariable("Path", "$userPath;$dir", "User") }
+& "$dir\tslime.exe" --version
+```
 
-- **Windows** — `tslime-windows-x86_64.exe`. SmartScreen may warn about the
-  unsigned executable; click **More info → Run anyway**.
+Open a new terminal afterwards so the `PATH` change takes effect (or run
+`$env:Path += ";$dir"` in the current one), then just run `tslime`.
 
 > macOS prebuilt binaries are not published — use Homebrew or `cargo install`
 > (both avoid Gatekeeper). ARM Linux (aarch64): use `cargo install`.
