+### Ignoring Aliases
+
+The user can ignore aliases by adding them to a `.aliasignore` file in the root
+of the directory where `nu-alias-converter` is run.
+
+The file should contain all the aliases that should be ignored, one per line:
+
+```plaintext
+ls
+la
+gst
+```
+
+This will not convert any of those aliases to nushell.
+
+Another option is to ignore all the aliases that use a command, the syntax would
+be the same but with a bang (`!`) in front of the command name:
+
+```plaintext
+la
+gst
+!ls
+!htop
+```
+
+This will also ignore all the aliases that use `ls` and `htop`.
