-This script will monitor a dir and execute `reprepro` to include the new .deb files.
+This script will monitor an income dir and execute `reprepro` to
+include the new .deb files under the income dir.
 
 # Usage
 
+Create a directory as WORK_DIR, take `work` as example, and cd into it.
+
+```bash
+mkdir work
+cd work
 ```
-WORK_DIR=/srv/apt apt-repo-updater
+
+Create `conf/distributions` with content like the follow for `reprepro`
+to use, see more at [here](https://manpages.debian.org/jessie/reprepro/reprepro.1.en.html)
+
+```bash
+mkdir conf
+cat << EOF > conf/distributions
+Codename: bookworm
+Description: An example repository
+Architectures: amd64
+Components: main
+EOF
 ```
+
+Start apt-repo-updater
+
+```bash
+/path/to/apt-repo-updater --work-dir .
+```
+
+Use another terminal to copy a .deb into the INCOME_DIR created
+by apt-repo-updater, normally it will be named `income` under the WORK_DIR
+
+```bash
+cp /path/to/a/package.deb /path/to/WORK_DIR/income
+```
+
+Now the apt repository will include the .deb file just copyied.
+And the .deb file will be deleted after included in the repository.
