Installing a patch is as easy as using the Joomla! installer to override the current files. Patches have version numbers and letters. Letters go from A to Z, so a patch labeled E is more recent then a patch labeled B. Patches are good for the versions they indicate. So, a patch com.linkr.patch-231c is good for Linkr 2.3.1 as well as for a patched version Linkr 2.3.1(b), but not for an older version Linkr 2.3.0.

NOTE: Clear your cache after installing a patch.
