This project uses an outdated version of

[CIDER](https://github.com/clojure-emacs/cider), the package that

provides much of the functionality for Clojure development. If you run

into issues, try upgrading (instructions below).

Why not just update this package to use the latest CIDER, you ask?

This project uses CIDER 0.8.1 so that

[Clojure for the Brave and True](http://www.braveclojure.com/basic-emacs/)

readers are less likely to get confused as they use Emacs for the

first time.

1. Close Emacs.

2. Delete `~/.emacs` or `~/.emacs.d` if they exist. (Windows users, your

emacs files will probably live in

`C:\Users\your_user_name\AppData\Roaming\`. So, for example, you

would delete `C:\Users\jason\AppData\Roaming\.emacs.d`.) This is

where Emacs looks for configuration files, and deleting these files

and directories will ensure that you start with a clean slate.

3. Download the Emacs

[configuration zip file](https://github.com/flyingmachine/emacs-for-clojure/archive/book1.zip)

and unzip it. Its contents should be a folder,

`emacs-for-clojure-book1`. Run `mv path/to/emacs-for-clojure-book1

~/.emacs.d`.

4. Create the file `~/.lein/profiles.clj` (Windows users, this is

probably `C:\Users\your_user_name\.lein\profiles.clj`) and add this

line to it:

{:user {:plugins [[cider/cider-nrepl "0.8.1"]]}}

Then open Emacs.

Before upgrading, ensure that your `.emacs.d` directory is under

version control so that you can always revert to a known good state.

To upgrade:

1. Edit `.emacs.d/init.el`, adding these lines after line 12:

```elisp

```

2. Close Emacs.

3. Run `rm -Rf .emacs.d/elpa/cider-*`

4. Open Emacs. You'll probably see some errors and your theme won't

load. That's ok.

5. In Emacs, run `M-x package-refresh contents`.

6. In Emacs, run `M-x package-install cider`.

7. Close and re-open Emacs.

That should install the latest version. Enjoy!
