# One-click Updating
When an update is available, users with the permission to update Craft will see a badge in the control panel header. Clicking on that badge will take you to a page that shows the release notes of all the available updates.
You can get to that page at any time by clicking the “Check for updates” link in the control panel footer as well. Whenever you go to the page, whether Craft thinks updates are available or not, the page will clear its cache and re-check for available updates.
At the top of the page there is an “Update” button. Clicking that will initiate Craft Commerce’s self-updating process.
For one-click updates to work, your plugins folder and all its enclosed files and folders must be writable. The exact permissions you should use depend on the relationship between the user that Apache/PHP is running as and the user who actually owns the craft/config folder.
Here are some recommended permissions depending on that relationship:
If they are the same user, use 744. If they’re in the same group, then use 774. Otherwise, use 777.
