+> hub can be safely aliased as git, so you can type $ git <command> in the shell and have it expanded with hub features.
+
+Prior to aliasing:
+
+```bash
+$ hub --version
+git version 2.25.0
+hub version 2.14.1
+```
+
+```bash
+$ git --version
+git version 2.25.0
+```
+
+Aliasing:
+
+```bash
+$ alias git="hub"
+$ alias | grep hub
+alias git='hub'
+```
+
+After aliasing:
+
+```bash
+$ hub --version
+git version 2.25.0
+hub version 2.14.1
+```
+
+The alias should be put in your `.bash_profile` or equivalent.
