+# PowerShell Configuration
+
+This directory contains PowerShell equivalents of the bash functions from `.bashrc.arch`.
+
+## Functions
+
+### `fcd` - Fuzzy Change Directory
+Searches through predefined directories and allows fuzzy selection:
+- `~/.config` directories
+- `~/.cache` directories  
+- `~/ghq` repositories (2 levels deep)
+- Home directories (excluding .git)
+
+Usage:
+```powershell
+fcd           # Interactive fuzzy search
+fcd dotfiles  # Quick filter and select best match
+```
+
+### `cl` - Clone Repository
+Smart git clone that organizes repositories in `~/ghq` structure.
+
+Usage:
+```powershell
+cl repo-name                    # Clones from github.com/juancwu/repo-name
+cl hub repo-name               # Clones from github.com/juancwu/repo-name
+cl lab repo-name               # Clones from gitlab.com/juancwu/repo-name
+cl hub namespace repo-name     # Clones from github.com/namespace/repo-name
+cl git@github.com:user/repo.git # Clones using full URL
+```
+
+### `cdf` - Change Directory Fuzzy
+Searches all subdirectories from current location.
+
+Usage:
+```powershell
+cdf          # Interactive fuzzy search
+cdf src      # Quick filter for directories containing "src"
+```
+
+## Installation
+
+### Automatic Setup
+```powershell
+cd ~/ghq/juancwu/dotfiles/powershell
+./setup.ps1
+```
+
+### Manual Setup
+1. Copy profile to PowerShell profile location:
+   ```powershell
+   cp Microsoft.PowerShell_profile.ps1 $PROFILE
+   ```
+
+2. Install dependencies:
+   - **fzf** (required for fuzzy search):
+     ```powershell
+     # Using Scoop
+     scoop install fzf
+     
+     # Using Chocolatey
+     choco install fzf
+     
+     # Using PowerShell Gallery
+     Install-Module -Name PSFzf -Scope CurrentUser
+     ```
+
+3. Reload profile:
+   ```powershell
+   . $PROFILE
+   ```
+
+## Notes
+
+- The functions maintain compatibility with the bash versions
+- Node version switching with nvm is supported in `fcd`
+- Git aliases like `gs` for `git status` are included
+- All paths use PowerShell's cross-platform `$env:HOME` variable
