| - | * ''-f'': If you already have the version to be installed, the basic ''lsup'' command will abort. The ''-f'' option forces ''lsup'' to install even if the version you have is the same version as the LSWS to be installed. This can be useful if there has been a change in the build since you upgraded, but a new build has not yet been released. | + | * ''-f'': If you already have the most recent stable version installed, the basic ''lsup'' command will abort. The ''-f'' option forces ''lsup'' to install the latest edge build. |
| - | * ''-v'': You can control what version you install with the ''-v'' option followed by a version number. (For example: ''./lsup.sh -v 4.2.2'') This will allow you to downgrade to older versions if you run into a bug. Keep in mind, LiteSpeed only keeps the most recent few versions available. Much older versions are not available. | + | * ''-v'': You can control what version you install with the ''-v'' option followed by a version number. (For example: ''./lsup.sh -v 5.3.4'') This will allow you to downgrade to older versions if you run into a bug. |
| * ''-b'': Designates a build number. All versions start from build ''0''. To view what build you are currently using, view ''/usr/local/lsws/autoupdate/build''. Will automatically upgrade to the latest build of the designated version if ''-b'' is not set. (Only available for versions 5.0 and higher.) | * ''-b'': Designates a build number.

This will make your server more stable during the upgrade, while still keeping edge users in mind. Here's how it works: |
| - | * Basically ''/usr/local/lsws/autoupdate/follow_stable'' marker will be set automatically as far as you upgrade to 5.3.7 build 4 or later version. | + | * The ''/usr/local/lsws/autoupdate/follow_stable'' marker will be set automatically when you upgrade to 5.3.7 build 4 or a later version. |
| - | * If you want to setup cron job, please ensure ''lsup.sh'' without parameter is used instead of ''lsup.sh -f''. | + | * If you want to set up a cron job, please use ''lsup.sh'' without any parameters instead of using ''lsup.sh -f''. |
| - | * ''lsup.sh'' without parameter will follow stable tier if ''follow_stable'' marker is set and stable tier number is controlled. | + | * ''lsup.sh'' without a parameter will follow the Stable Tier if the ''follow_stable'' marker is set, and the Stable Tier number is controlled. |
| - | * ''lsup.sh -f'' will install the edge build, which is the latest build available. and it will stop following stable tier by removing the ''follow_stable'' marker. | + | * ''lsup.sh -f'' will install the edge build, which is the latest build available, and it will stop following the Stable Tier by removing the ''follow_stable'' marker. |
| - | * If a version is forced, such as ''lsup.sh -f -v <version>'', "lsup.sh" will stop follow stable and "lsup.sh" will do nothing. | + | * If a particular version is forced, such as with ''lsup.sh -f -v <version>'', the ''lsup.sh'' command without parameters will stop following the Stable Tier, and will do nothing. |
| - | * You can manually create follow_stable marker by running ''touch /usr/local/lsws/autoupdate/follow_stable'', then it will start to follow stable tier again after the reset. | + | * To start following the Stable Tier again, you can manually create a ''follow_stable'' marker by running ''touch /usr/local/lsws/autoupdate/follow_stable''. |
| - | * Why ''follow_stable'' is important? When you try to install a test build/debug build, or downgrade to an older version, you certainly do not want ''lsup.sh'' in daily cron job to change it to stable tier automatically during the test. In these situations, unset ''follow_stable'' will make ''lsup.sh'' do noting in cron job. | + | * Why is ''follow_stable'' important?
