h1. Instructions for installing CentOS on your computer h2. Why CentOS? If you have a new computer(s) for your Leginon/Appion installation, we recommend installing CentOS because it is considered to be more stable than other varieties of Linux. CentOS is the same as Red Hat Enterprise Linux (RHEL), except that it is free and supported by the community. We have most experience in the installation on CentOS and this installation guide has specific instruction for the process. see [[Select_Linux_distribution_to_use|Linux distribution recommendation]] for more. h2.
