+## Lines starting with two hashes (##) are comments containing information

+###################################
+##
+## Optimal configuration is taken from:
+## https://raymii.org/s/tutorials/Strong_SSL_Security_On_nginx.html
+## Make sure to read it and understand what each option does.
+##
+## [Optional] Generate a self-signed ssl certificate:
+##    mkdir /etc/nginx/ssl/
+##    cd /etc/nginx/ssl/
+##    sudo openssl req -newkey rsa:2048 -x509 -nodes -days 3560 -out gitlab.crt -keyout gitlab.key
+##    sudo chmod o-r gitlab.key
+##
+## Edit `gitlab-shell/config.yml`:
+##  1) Set "gitlab_url" param in `gitlab-shell/config.yml` to `https://git.example.com`
+##  2) Set "ca_file" to `/etc/nginx/ssl/gitlab.crt`
+##  3) Set "self_signed_cert" to `true`
+## Edit `gitlab/config/gitlab.yml`:
+##  1) Define port for http "port: 443"
+##  2) Enable https "https: true"
+##  3) Update ssl for gravatar "ssl_url: https://secure.gravatar.com/avatar/%{hash}?s=%{size}&d=mm"

+##        CHUNKED TRANSFER      ##
+##################################
+##
+## It is a known issue that Git-over-HTTP requires chunked transfer encoding [0]
+## which is not supported by Nginx < 1.3.9 [1]. As a result, pushing a large object
+## with Git (i.e. a single large file) can lead to a 411 error. In theory you can get
+## around this by tweaking this configuration file and either:
+## - installing an old version of Nginx with the chunkin module [2] compiled in, or
+## - using a newer version of Nginx.
+##
+## At the time of writing we do not know if either of these theoretical solutions works. As a workaround
+## users can use Git over SSH to push large files.
