Before compiling Celestia, you must obtain the source code. The very latest source code is kept in Celestia's GitHub repository. You can get the source code by following these instructions:

  1. Open Terminal
  2. See if Git is installed on your system. Type "git" in the terminal (without the quotes.) If you get a "command not found" error message, you need to install Git. See this guide for information on installing Git on Mac OS X.
  3. Type, or paste in: git clone https://github.com/CelestiaProject/Celestia.git
  4. Wait for a while, until the download is complete.
  5. cd Celestia and follow instructions from https://github.com/CelestiaProject/Celestia/blob/master/INSTALL.md
