First, make sure you have pip installed for python3 and gulp,

$ curl 'https://bootstrap.pypa.io/get-pip.py' | sudo python3 -
$ sudo npm install -g gulp

Now, install all the dependencies,

$ sudo pip3 install -r requirements.txt

Compile the front-end code,

$ cd web
$ npm install
$ gulp production
$ cd ..

Lastly, you'll want to decrypt the config files. Simply run,

$ python3 config_packer.py decrypt config.conf.enc > config.conf

Similarly, if you changed the config.conf file, run the following to encrypt your changes,

$ python3 config_packer.py encrypt config.conf > config.conf.enc

Finally, run the script,

$ python3 api.py

Normally when creating a showtime, we take the passphrase that encrypts that show and split it into shares. At least 2 of these shares are required to decrypt the contents of that show. If you set share_threshold in config to 1, we instead just send out the passphrase to make development easier. The ShowtimeAccessTokens endpoint will take either multiple shares (as we would expect in production) or a passphrase option for the dev case. Just remember to change the dev:shares_email config field in config.conf so that you get the e-mail with the passphrase!
