23+Assuming everything goes correctly (potential problems are discussed later), this will install the `elm` compiler on your machine. `elm` is a standard compiler that takes `.elm` files and produces `.html` and/or `.js` files. You can then use these files with your favorite web-framework. Use `elm --help` for more directions on how to use it.

25+If you have this installed you can write and compile Elm locally.
27+You can also install `elm-server` which is both a compiler and server, allowing you to develop without designing and setting up a server yourself. Running `elm-server` starts a server in the current directory. It will compile and serve any `.elm` files in the current directory and its sub-directories. This is how I prefer to develop Elm programs. Install with:
29+ cabal install elm-server

26To use these executables you need to add a new directory to your PATH. For me, the executables were placed in `/home/evan/.cabal/bin` which I appended to the end of my PATH variable in my .bashrc file. Cabal should tell you where your executables are located upon successful installation, so you can make a similar addition (see this tutorial if you are new to changing your PATH in [Unix/Linux](http://www.cyberciti.biz/faq/unix-linux-adding-path/)).
