\usage{
lift(input = NULL, use_config = FALSE, config_file = "_liftr.yml",
  output_dir = NULL)
}
\arguments{
\item{input}{Input (R Markdown) file.}

\item{use_config}{If \code{TRUE}, will parse the liftr metadata from
a YAML file, if \code{FALSE}, will parse such information from the
metadata section in the R Markdown file. Default is \code{FALSE}.}

\item{config_file}{Name of the YAML configuration file, under the
same directory as the input file. Default is \code{"_liftr.yml"}.}

\item{output_dir}{Directory to output \code{Dockerfile}.
If not provided, will be the same directory as \code{input}.}
}
\value{
\code{Dockerfile}.

\description{
Containerize R Markdown documents. This function generates
\code{Dockerfile} based on the liftr metadata in the RMD document.
}
\details{
After running \link{lift}, run \link{render_docker} on the document to
render the containerized R Markdown document using Docker containers.
See \code{vignette('liftr-intro')} for details about the extended
YAML front-matter metadata format used by liftr.
