* Download the game
* Copy contents of original *Jazz Jackrabbit 2* directory to `‹Game›\Source\`
* Run `‹Game›\Jazz2.exe`, `‹Game›\Jazz2_avx2.exe` or `‹Game›\Jazz2_sdl2.exe` application

`‹Game›` *denotes path to Jazz² Resurrection. The game requires **Windows 7** (or newer) and GPU with **OpenGL 3.3** support. Game files should **not** be copied to* `Program Files`*. Cache is recreated during the intro cinematics on the first startup, so it can't be skipped. Also, the sound effects in the intro cinematics require the cache, so they will be missing the first time the game is started up.*

### Linux
* Download the game
* Install dependencies: `sudo apt install libcurl4 libglew2.2 libglfw3 libsdl2-2.0-0 libopenal1 libvorbisfile3 libopenmpt0`
  * Alternatively, install provided `.deb` or `.rpm` package and dependencies should be installed automatically
* Copy contents of original *Jazz Jackrabbit 2* directory to `‹Game›/Source/`
  * If packages are used, the files must be copied to `~/.local/share/Jazz² Resurrection/Source/` or `/usr/local/share/Jazz² Resurrection/Source/` instead, please follow instructions of specific package
* Run `‹Game›/jazz2` or `‹Game›/jazz2_sdl2` application
  * If packages are used, the game should be visible in application lists

`‹Game›` *denotes path to Jazz² Resurrection.* `~` *denotes user's home directory. The game requires GPU with **OpenGL 3.3** or **OpenGL ES 3.0** (ARM) support. Cache is recreated during the intro cinematics on the first startup, so it can't be skipped. Also, the sound effects in the intro cinematics require the cache, so they will be missing the first time the game is started up.*
