+### Automatic repo detection and running
+
+If you want to automate the detection and running of `onefetch` every time you `cd` into a repository you can leverage one of the methods below:
+
+#### 1. Bash / Zsh
+
 By [**@quazar-omega**](https://github.com/quazar-omega)
 
 A script to put in your `.bashrc` - or `.zshrc` - to run onefetch whenever you open a shell into a repository or `cd` into a repository, making sure that it's different from the last one you were in:
+
 ```sh
 # git repository greeter
 last_repository=
 check_directory_for_new_repository() {
-	current_repository=$(git rev-parse --show-toplevel 2> /dev/null)
-	
-	if [ "$current_repository" ] && \
-	   [ "$current_repository" != "$last_repository" ]; then
-		onefetch
-	fi
-	last_repository=$current_repository
+ current_repository=$(git rev-parse --show-toplevel 2> /dev/null)
+ 
+ if [ "$current_repository" ] && \
+    [ "$current_repository" != "$last_repository" ]; then
+  onefetch
+ fi
+ last_repository=$current_repository
 }
 cd() {
-	builtin cd "$@"
-	check_directory_for_new_repository
+ builtin cd "$@"
+ check_directory_for_new_repository
 }
 
 # optional, greet also when opening shell directly in repository directory
 # adds time to startup
 check_directory_for_new_repository
 ```

+#### 4. Powershell
+
+By [**@kiapanahi**](https://github.com/kiapanahi)
+
+An adaptation of the above snippet suited for `Powershell`. Put this script in the `$PROFILE`.
+
+```pwsh
+# git repository greeter
+$global:lastRepository = $null
+
+function Check-DirectoryForNewRepository {
+    $currentRepository = git rev-parse --show-toplevel 2>$null
+    if ($currentRepository -and ($currentRepository -ne $global:lastRepository)) {

+    )

+    # Use the default Set-Location to change the directory
+    Microsoft.PowerShell.Management\Set-Location -Path $path
+
+    # Check if we are in a new Git repository
+    Check-DirectoryForNewRepository
+}
+
+# Optional: Check the repository also when opening a shell directly in a repository directory
+# Uncomment the following line if desired
+#Check-DirectoryForNewRepository
+```
+
+### Git alias
+
 By [**@mbrehin**](https://github.com/mbrehin)
+
+You can also add git alias to run onefetch during your git workflows
+
 ```sh
 # Add Git alias for onefetch.
 git config --global alias.project-summary '!which onefetch && onefetch'
