Visual component containing the animated "running cheetah" from the freepascal websites to show that your application was developed using FreePascal/Lazarus. See a screenshot in the file "Screenshot.png".
Download all files as zip. Unpack the zip to a random place. You will have to keep the files at that place after installation. Open the Lazarus IDE, and install the package. Therefore click menue "Package" -> "Open Package File (.lpk)". Choose "runningcheetah.lpk", the package dialog opens. Press "Use" -> "Install". Confirm to rebuild the Lazarus IDE.
After installation you can find the component in the component palette under "Additional".
