-#Advanced installation
-
-## Development
-
-If you plan on developing dokku, the easiest way to install from your own repository is cloning
-the repository and calling the install script. Example:
-
-    $ git clone https://github.com/yourusername/dokku.git
-    $ cd dokku
-    $ sudo make install
-
-The `Makefile` allows source URLs to be overridden to include customizations from your own
-repositories. The `DOCKER_URL`, `PLUGINHOOK_URL`, `SSHCOMMAND_URL` and `STACK_URL`
-environment variables may be set to override the defaults (see the `Makefile` for how these
-apply). Example:
-
-    $ sudo SSHCOMMAND_URL=https://raw.github.com/yourusername/sshcommand/master/gitreceive make install
-
-## Bootstrap a server from your own repository
-
-The bootstrap script allows the dokku repository URL to be overridden to bootstrap a host from
-your own clone of dokku using the `DOKKU_REPO` environment variable. Example:
-
-    $ wget https://raw.github.com/progrium/dokku/master/bootstrap.sh
-    $ chmod +x bootstrap.sh
-    $ sudo DOKKU_REPO=https://github.com/yourusername/dokku.git ./bootstrap.sh
-
-## Custom buildstep build
-
-Dokku ships with a pre-built version of version of the [buildstep] component by
-default. If you want to build your own version you can specify that with an env
-variable.
-
-    $ git clone https://github.com/progrium/dokku.git
-    $ cd dokku
-    $ sudo BUILD_STACK=true make install
