The Engine Settings Page allows you to add new chess engines to be used by the engine analysis feature, and lets you configure and manage existing engines. Before the engine analysis feature can be used, at least one engine must be added.

To add a new engine, use the Add New UCI Engine button. You will be shown a window allowing you to find the engine executable on your computer hard drive. This must be a UCI compatible engine. UCI is a standard used to communicate with chess engines, most modern chess engines utilise the UCI protocol. It is important that you select the actual engine executable and not the executable of the user interface that comes with the engine. This is an especially important point on Mac OS X where the .app file associated with your engine is actually a directory hiding the engine executable, not the executable itself. Once selected, you will be shown the engine name and all the configurable parameters of the engine.

By default, engines are identified by the name provided by the engine author. You can however change the engine nickname to use your own identifier. This allows you to have the same engine with different settings, or to make it clear which engine you are using when you have added engines on different machines, with different engine executable locations.

If you change any engine parameters (including the engine nickname), you need to click the Save Options button to save the setings to the server.

If you want to remove an engine from your available engine list, use the Discard Engine button. Note, that this only removes the record of the engine from your Chess Tempo settings, the engine itself will remain on your computer's hard drive.
