Install straight from the repo with one piped command

Piped in via irm | iex there is no checkout next to the script, so the
installer now notices that and fetches the repository archive to %TEMP%
itself. README documents the one-liner, the download-and-run variant for
switches, and the clone path.

 ## Setup
 
+One line, on any machine that can reach the repo (PowerShell 5.1 is fine):
+
 ```powershell
-cd c:\Users\smoido\Projects\cli\claude-code-switcher
+irm https://git.nebulm.com/smoido/claude-mode/raw/branch/master/install.ps1 | iex
+```
+
+Piped in like that there is no checkout, so the installer fetches the
+repository archive to `%TEMP%` and installs from it. To pass switches
+(`-Force`, `-SkipKeyPrompt`), download first and run the file:
+
+```powershell
+irm https://git.nebulm.com/smoido/claude-mode/raw/branch/master/install.ps1 -OutFile install.ps1
+.\install.ps1 -Force
+```
+
+Or clone it — the normal path if you want to read the code and pull updates:
+
+```powershell
+git clone https://git.nebulm.com/smoido/claude-mode.git
+cd claude-mode
 .\install.ps1
 ```
 
-Installs to `~/.claude-mode/` (ACL: you only), drops `claude-mode.cmd` into
-`~/.local/bin` (already on your User PATH, next to `claude.exe`), and adds a
-marked block to `~/Documents/WindowsPowerShell/profile.ps1`.
+All three install the same way: to `~/.claude-mode/` (ACL: you only), dropping
+`claude-mode.cmd` into `~/.local/bin` (already on your User PATH, next to
+`claude.exe`), and adding a marked block to
+`~/Documents/WindowsPowerShell/profile.ps1`.
 `~/.claude/settings.json` is **not** touched by the installer — only by an actual
 mode switch, which backs it up to `~/.claude-mode/backups/` first (last 20 kept).
 
+Re-running any of them is a safe upgrade: scripts are overwritten, existing
+presets are kept unless `-Force` is passed.
+
 If the profile doesn't load: `Set-ExecutionPolicy -Scope CurrentUser RemoteSigned`.
