If you are installing from a CD or a DVD that is part of a larger set, the installer will ask if you want to scan additional CDs or DVDs. If you have additional CDs or DVDs available, you probably want to do this so the installer can use the packages included on them.
If you do not have any additional CDs or DVDs, that is no problem: using them is not required. If you also do not use a network mirror (as explained in the next section), it can mean that not all packages belonging to the tasks you select in the next step of the installation can be installed.
Note: Packages are included on CDs (and DVDs) in the order of their popularity. This means that for most uses only the first CDs in a set are needed and that only very few people actually use any of the packages included on the last CDs in a set.
It also means that buying or downloading and burning a full CD set is just a waste of money as you’ll never use most of them. In most cases you are better off getting only the first 3 to 8 CDs and installing any additional packages you may need from the Internet by using a mirror. The same goes for DVD sets: the first DVD, or maybe the first two DVDs will cover most needs.
If you do scan multiple CDs or DVDs, the installer will prompt you to exchange them when it needs packages from another CD/DVD than the one currently in the drive. Note that only CDs or DVDs that belong to the same set should be scanned. The order in which they are scanned does not really matter, but scanning them in ascending order will reduce the chance of mistakes.
