+# Basic setup
+
+The basic installation will provide you a GitLab setup with options:
+
+1. ruby 1.9.3
+2. mysql as main db
+3. gitolite v3 fork by gitlab
+4. nginx + unicorn
+
+The installation consists of next steps:
+
+1. Packages / dependencies
+2. Ruby
+3. Users
+4. Gitolite
+5. Mysql
+6. GitLab.
+7. Nginx 
+
+
+# 1. Packages / dependencies
+
+*Keep in mind that `sudo` is not installed on Debian by default. You should install it as root:*
+
+    apt-get update && apt-get upgrade && apt-get install sudo
+
+Now install the required packages:
+
+    sudo apt-get update
+    sudo apt-get upgrade
+
+    sudo apt-get install -y wget curl gcc checkinstall libxml2-dev libxslt-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev libmysql++-dev make build-essential zlib1g-dev libicu-dev redis-server openssh-server git-core python-dev python-pip libyaml-dev postfix libpq-dev
+
+    sudo pip install pygments
+
+
+# 2. Install Ruby
+
+    wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p194.tar.gz
+    tar xfvz ruby-1.9.3-p194.tar.gz
+    cd ruby-1.9.3-p194
+    ./configure
+    make
+    sudo make install
+
+# 3. Users
+
+Create user for git:
+
+    sudo adduser \
+      --system \
+      --shell /bin/sh \
+      --gecos 'git version control' \
+      --group \
+      --disabled-password \
+      --home /home/git \
+      git
+
+Create user for GitLab:
+
+    # ubuntu/debian
+    sudo adduser --disabled-login --gecos 'gitlab system' gitlab
+
+Add your users to groups:
+
+    sudo usermod -a -G git gitlab
+    sudo usermod -a -G gitlab git
+
+Generate key:
+
+    sudo -H -u gitlab ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa
+
+
+# 4. Gitolite
+
+Clone GitLab's fork of the Gitolite source code:
+
+    sudo -H -u git git clone -b gl-v304 https://github.com/gitlabhq/gitolite.git /home/git/gitolite
+
+Setup:
+
+    cd /home/git
+    sudo -u git -H mkdir bin
+    sudo -u git sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" >> /home/git/.profile'
+    sudo -u git sh -c 'gitolite/install -ln /home/git/bin'
+
+    sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
+    sudo chmod 0444 /home/git/gitlab.pub
+
+    sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gitolite setup -pk /home/git/gitlab.pub"
+    sudo -u git -H sed -i 's/0077/0007/g' /home/git/.gitolite.rc
+    sudo -u git -H sed -i "s/\(GIT_CONFIG_KEYS\s*=>*\s*\).\{2\}/\1'\.\*'/g" /home/git/.gitolite.rc
+
+Permissions:
+
+    sudo chmod -R g+rwX /home/git/repositories/
+    sudo chown -R git:git /home/git/repositories/
+
+    # clone admin repo to add localhost to known_hosts
+    # & be sure your user has access to gitolite
+    sudo -u gitlab -H git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin
+
+    # if succeed  you can remove it
+    sudo rm -rf /tmp/gitolite-admin
+
+**IMPORTANT! If you can't clone `gitolite-admin` repository - DO NOT PROCEED WITH INSTALLATION**
+Check the [Trouble Shooting Guide](https://github.com/gitlabhq/gitlab-public-wiki/wiki/Trouble-Shooting-Guide)
+and ensure you have followed all of the above steps carefully.

+
+# 5. Mysql database
+
+    sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev
+
+    # Login to MySQL
+    $ mysql -u root -p
+
+    # Create the GitLab production database
+    mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;
+
+    # Create the MySQL User change $password to a real password
+    mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';
+
+    # Grant proper permissions to the MySQL User
+    mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';
+
+
+# 6. GitLab
+
+    cd /home/gitlab
+
+
+#### Get source code
+
+    # Get gitlab code. Use this for stable setup
+    sudo -H -u gitlab git clone -b stable https://github.com/gitlabhq/gitlabhq.git gitlab
+
+    # Skip this for stable setup.
+    # Master branch (recent changes, less stable)
+    sudo -H -u gitlab git clone -b master https://github.com/gitlabhq/gitlabhq.git gitlab
+
+
+#### Copy configs
+ 
+    cd gitlab
+
+    # Rename config files
+    #
+    sudo -u gitlab cp config/gitlab.yml.example config/gitlab.yml
+
+    # Copy mysql db config
+    #
+    # make sure to update username/password in config/database.yml
+    #
+    sudo -u gitlab cp config/database.yml.mysql config/database.yml
+
+    # Copy unicorn config
+    #
+    sudo -u gitlab cp config/unicorn.rb.example config/unicorn.rb
+
+#### Install gems
+
+    cd /home/gitlab/gitlab
+
+    sudo gem install charlock_holmes --version '0.6.8'
+    sudo gem install bundler
+    sudo -u gitlab -H bundle install --without development test sqlite postgres  --deployment
+
+#### Setup application
+
+    sudo -u gitlab bundle exec rake gitlab:app:setup RAILS_ENV=production
+
+
+#### Setup GitLab hooks
+
+    sudo cp ./lib/hooks/post-receive /home/git/.gitolite/hooks/common/post-receive
+    sudo chown git:git /home/git/.gitolite/hooks/common/post-receive
+
+#### Check application status
+
+Checking status:
+
+    sudo -u gitlab bundle exec rake gitlab:app:status RAILS_ENV=production
+
+
+    # OUTPUT EXAMPLE
+    Starting diagnostic
+    config/database.yml............exists

+    /home/git/share/gitolite/hooks/common/post-receive exists? ............YES
+
+If you got all YES - congratulations! You can run a GitLab app.
+
+#### init script
+
+Create init script in /etc/init.d/gitlab:
+
+    sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/init.d/gitlab -P /etc/init.d/
+    sudo chmod +x /etc/init.d/gitlab
+
+GitLab autostart:
+
+    sudo update-rc.d gitlab defaults 21
+
+#### Now you should start GitLab application:
+
+    sudo service gitlab start
+
+
+# 7. Nginx
+
+    # Install first
+    sudo apt-get install nginx
+
+    # Add GitLab to nginx sites & change with your host specific settings
+    sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab -P /etc/nginx/sites-available/
+    sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab
+
+    # Change **YOUR_SERVER_IP** and **YOUR_SERVER_FQDN**
+    # to the IP address and fully-qualified domain name
+    # of the host serving GitLab.
+    sudo vim /etc/nginx/sites-enabled/gitlab
+
+    # Restart nginx:
+    sudo /etc/init.d/nginx restart
+
+
+# Done!  Visit YOUR_SERVER for gitlab instance
+
+You can login via web using admin generated with setup:
+
+    admin@local.host

+> The first 3 steps of this guide can be easily skipped by executing an install script:
+>
+>     # Install curl and sudo
+>     apt-get install curl sudo
+>
+>     # 3 steps in 1 command :)
+>     curl https://raw.github.com/gitlabhq/gitlab-recipes/master/install/debian_ubuntu.sh | sh
+>
+> Now you can go to [Step 4](#4-install-gitlab-and-configuration-check-status-configuration)
+>
+> Or if you are installing on Amazon Web Services using Ubuntu 12.04 you can do all steps (1 to 6) at once with:
+>
+>     curl https://raw.github.com/gitlabhq/gitlab-recipes/master/install/debian_ubuntu_aws.sh | sh
+>
+> for more detailed instructions read the HOWTO section of [the script](https://github.com/gitlabhq/gitlab-recipes/blob/master/install/debian_ubuntu_aws.sh)

+## Customizing Resque's Redis connection
+
+If you'd like Resque to connect to a Redis server on a non-standard port or on
+a different host, you can configure its connection string in the
+**config/resque.yml** file:
+
+    production: redis.example.com:6379
+
+**Ok - we have a working application now. **
+**But keep going - there are some things that should be done **
