There is no update routine. You need to refresh your pulled repository clone and apply your local changes (if any). Actually there are many ways to merge local changes.
### Step 1, method 1
Stash all local changes, pull changes from the remote master branch and apply your stash on top of it. You will most likely see warnings about non-commited changes; you can ignore them:
If git complains about conflicts, solve them! Example:
```
CONFLICT (content): Merge conflict in data/web/index.php
```
Open `data/web/index.php`, solve the conflict, close the file and run `git add -A` + `git commit -m "Solved conflict"`.
### Step 1, method 3

In case both methods do not work (for many reason like you're unable to fix the CONFLICTS or any other reasons) you can simply start all over again.
Keep in mind that all local changes _to configuration files_ will be lost. However, your volumes will not be removed.
- Copy mailcow.conf somewhere outside the mailcow-dockerized directory
- Stop and remove mailcow containers: `docker-compose down`
- Delete the directory or rename it
- Clone the remote repository again (`git clone https://github.com/andryyy/mailcow-dockerized && cd mailcow-dockerized`). **Pay attention** to this step - the folder must have the same name of the previous one!
