How do I get started?

cd into the directory where you've installed the source, type ./configure. If configure balks at your supporting libraries, you'll have to go back and compile or install the proper version.

You should now be able to type make and build the executables. Once this is done you can type make install to install the Terraform executable and any supporting files it needs. If you want to change any of the startup defaults, you can copy the file system.terraformrc to $HOME/.terraformrc. Try terraform --helprc or terraform --installrc for more details.
