First, download and install our Python bindings and example scripts on your Git server.

Next, create the stream you'd like to use for Git notifications, and subscribe all interested parties to this stream. The integration will use the default stream commits if no stream is supplied in the hook; you still need to create the stream even if you are using this default.

Next, open integrations/git/zulip_git_config.py in your favorite editor, and change the following lines to specify the email address and API key for your Git bot:

ZULIP_USER = "git-bot@example.com"
ZULIP_API_KEY = "0123456789abcdef0123456789abcdef"
{% if api_site_required %}ZULIP_SITE ="{{ external_api_uri_subdomain }}"{% endif %}

You can also specify which pushes will result in notifications and to what stream the notifications will be sent by modifying the commit_notice_destination function in zulip_git_config.py. By default, pushes to the master and test-post-receive branches will result in a notification to stream commits.

Save integrations/git/zulip_git_config.py to the .git/hooks directory of your git repository.

Symlink /usr/local/share/zulip/integrations/git/post-receive into the .git/hooks directory of your git repository.

Congratulations! You're done!
Whenever you make a push to the master branch of your git repository (or whatever you configured above), the Zulip git plugin will send an automated notification that looks like this:

Testing
You can test the plugin without changing your master branch by pushing to the test-post-receive branch.
