-Or if you prefer, you can also use git aliases (instead of shell aliases). To do this:
-1. Set the `FORGIT_STANDALONE` flag
-    - example: `export FORGIT_STANDALONE=1`
-2. Add the bin directory in `FORGIT_INSTALL_DIR` to your `PATH`
-    - example: `PATH="$PATH:$FORGIT_INSTALL_DIR/bin"`

+#### git
+
+You can use git aliases by making `git-forgit` available in `$PATH`:
+
+```sh
+# after `forgit` was loaded
+export PATH="$PATH:$FORGIT_INSTALL_DIR/bin"
+```
+
+*Some plugin managers can help do this.*
+
+Then any forgit command will be a subcommand of git:
+
+```
+$ git forgit log
+$ git forgit add
+$ git forgit diff
+```
+
+Optionally you can add [aliases in git](https://git-scm.com/book/en/v2/Git-Basics-Git-Aliases):
+
+```sh
+git config --global alias.cf 'forgit checkout_file'
+```
+
+And use the alias in git:
+
+```sh
+git cf
+```
