+
+### Definition
+
+These scripts should be used to demonstrate how combine the power of nushell with git commands.
+
+### Aliases
+If you find some of these scripts useful you can add them as aliases in your git config file.
+
+For instance you can create a nushell script in your computer and define in your git config file an alias that call that script:
+```
+[alias]
+    bcl = !nu \"D:\\Tools\\gitalias_bcl.nu\"
+```
