### Installing the source directly from git

git submodule update --init --recursive
After that, run one of the following:
./bin/passenger-install-apache2-module
-OR-
./bin/passenger-install-nginx-module
-OR-
# From your application directory
~/path-to-passenger/bin/passenger start
For troubleshooting, configuration and tips, please also refer to the above documentation. For further support, please refer to [the Phusion Passenger support page](https://www.phusionpassenger.com/support).
Ruby users can also build a gem from the Git repository and install the gem.
gem build passenger.gemspec
gem install passenger-x.x.x.gem
