+### Issue weight
+
+Issue weight allows us to get an idea of the amount of work required to solve
+one or multiple issues. This makes it possible to schedule work more accurately.
+
+You are encouraged to set the weight of any issue. Following the guidelines
+below will make it easy to manage this, without unnecessary overhead.
+
+1. Set weight for any issue at the earliest possible convenience
+1. If you don't agree with a set weight, discuss with other developers until
+consensus is reached about the weight
+1. Issue weights are an abstract measurement of complexity of the issue. Do not
+relate issue weight directly to time. This is called [anchoring](https://en.wikipedia.org/wiki/Anchoring)
+and something you want to avoid.
+1. Something that has a weight of 1 (or no weight) is really small and simple.
+Something that is 9 is rewriting a large fundamental part of GitLab,
+which might lead to many hard problems to solve. Changing some text in GitLab
+is probably 1, adding a new Git Hook maybe 4 or 5, big features 7-9.
+1. If something is very large, it should probably be split up in multiple
+issues or chunks. You can simply not set the weight of a parent issue and set
+weights to children issues.
+

+# Environment Variables
+
+## Introduction
+
+Commonly people configure GitLab via the gitlab.rb configuration file in the Omnibus package.
+
+But if you prefer to use environment variables we allow that too.
+
+## Supported environment variables
+
+Variable | Type | Explanation
+-------- | ---- | -----------
+GITLAB_ROOT_PASSWORD | string | sets the password for the `root` user on installation
+GITLAB_HOST | url | hostname of the GitLab server includes http or https
+RAILS_ENV | production / development / staging / test | Rails environment
+DATABASE_URL | url | For example: postgresql://localhost/blog_development?pool=5
+GITLAB_EMAIL_FROM | email | Email address used in the "From" field in mails sent by GitLab
+GITLAB_EMAIL_DISPLAY_NAME | string | Name used in the "From" field in mails sent by GitLab
+GITLAB_EMAIL_REPLY_TO | email | Email address used in the "Reply-To" field in mails sent by GitLab
+
+## Complete database variables
+
+As explained in the [Heroku documentation](https://devcenter.heroku.com/articles/rails-database-connection-behavior) the DATABASE_URL doesn't let you set:
+
+- adapter
+- database
+- username
+- password
+- host
+- port
+
+To do so please `cp config/database.yml.env config/database.yml` and use the following variables:
+
+Variable | Default
+--- | ---
+GITLAB_DATABASE_ADAPTER | postgresql
+GITLAB_DATABASE_ENCODING | unicode
+GITLAB_DATABASE_DATABASE | gitlab_#{ENV['RAILS_ENV']
+GITLAB_DATABASE_POOL | 10
+GITLAB_DATABASE_USERNAME | root
+GITLAB_DATABASE_PASSWORD |
+GITLAB_DATABASE_HOST | localhost
+GITLAB_DATABASE_PORT | 5432
+
+## Adding more variables
+
+We welcome merge requests to make more settings configurable via variables.
+Please stick to the naming scheme "GITLAB_#{name 1_settings.rb in upper case}".
+
+## Omnibus configuration
+
+It's possible to preconfigure the GitLab image by adding the environment variable: `GITLAB_OMNIBUS_CONFIG` to docker run command.
+For more information see the ['preconfigure-docker-container' section in the Omnibus documentation](http://doc.gitlab.com/omnibus/docker/#preconfigure-docker-container).
