 This command will install a release compilation of the latest version locally to
 your user account. The same command also works for regular updates, this is, new
 commits have had been introduced since the last installation.

-Cargo will refuse to replace the currently installed executable if no new
-commits were found. To override the current binary with the latest repository 
-state anyway, rerun with `--force`:
-
-```
-cargo install --force --git https://github.com/wert007/commit-analyzer
-```
-
-Cargo will then replace the currently installed release binary with a newly
-compiled one from the latest repository state using the configured release
-profile.
