-h1. Spree Digital
-
-This is a spree extension to enable downloadable products. The design goal is to keep it robust. It should survive future spree versions out of the box.
-
-NOTE: This is still under development, but since things were falling into place, I thought I'd publish it.
-
-The idea is simple. You attach a file to a Product (or a Variant of this Product) and when people buy it, they will receive a link via email where they can download it once. There are a few assumptions that spree_digital (currently) makes and it's important to be aware of them. These might change, but since I programmed digital_spree over night, this is what you get ;)
-
-* The table structure of spree_core is not touched. Spree_digital lives parallel to spree_core and does not do any changes to your existing database, except adding two new tables.
-* The download links will be sent via email in the order confirmation (or "resend" from the admin section). The links do *not* appear in the order "overview" that the customer sees.
-* There should only be "live" payments. Once the order is checked-out, the download links will immediately be sent (i.e. in the order confirmation).
-* You should define a shipping method called "download" and it should be cost-free. Spree_digital will use that one when all products in the cart are digital
-* One may buy several items of the same digital product in one cart. The customer will simply receive several links by doing so. This allows customer's to legally purchase multiple copies of the same product and maybe give one away to a friend.
-* The links will only work 3 times (but we tell the customer that it works only once). After 24 hours the links are deactivated. This should keep you reasonably free from complaints of people who are not capable of appropriately clicking on a link. They can try a whole day long, 3 times per link. The file should really be downloadable for weird customers. I understand that this is a little bit security by obscurity, but it's better than other solutions that I've seen.
-* The file @views/order_mailer/confirm_email.text.erb@ is the only thing that should need customization. But since I assume you do that anyway, it doesn't hurt to do it when you're using spree_digital. The reason is that the download links are added to the confirmation email to the customer.
-* A purchased product can be downloaded even if you disable the product immediately. You would have to remove the attached file in your admin section to prevent people from downloading purchased products.
-* File are uploaded to @rails_root/private@. Make sure it's symlinked in case you're using Capistrano.
-* We use send_file to send the files on download. Yes, it goes through the entire stack right now.
-
-h2. Installation
-
-I assume that you already have a Rails 3 Spree application up and running. If not, the "Spree Documentation":http://spreecommerce.com/documentation will help you getting started.
-
-To make use of @digital_spree@, you need to add this line to your @Gemfile@:
-
-<pre>
-  gem 'spree_digital', :git => 'git://github.com/funkensturm/spree_digital.git', :branch => 'master'
-</pre>
-
-The following terminal commands will copy the file "spree_digital/db/migration/20110410134726_create_digitals.rb":http://github.com/funkensturm/spree_digital/blob/master/db/migrate/20110410134726_create_digitals.rb to the corresponding directory in your Rails application and apply the migration to your database.
-
-<pre>
-  rake spree_digital:install
-  rake db:migrate
-</pre>
-
-This should be all there is to do.
-
-h3. Important!
-
-You should go to the spree admin section and create a shipping method that has the word @download@ somehow in its name (it should be cost-free, but it doesn't have to). It will be detected by spree_digital. Otherwise your customer will be forced to choose something like "UPS" even if they purchase only downloadable products.

-h3. Table Diagram
-
-<img src="http://github.com/funkensturm/spree_digital/raw/master/doc/tables.png">
-
-h3. Installation (for Developers)
-
-Get the spree framework and spree_digital extension for it:
-
-<pre>
-  git clone git://github.com/spree/spree.git
-  git clone git://github.com/funkensturm/spree_digital
-</pre>
-
-Go into the spree directory and run the bundle command:
-
-<pre>
-  cd spree
-  bundle install
-</pre>
-
-Go into the spree_digital directory and do the same:
-
-NOTE: At this point you may need to uncomment the stuff in the @Gemfile@  before you can start developing and testing!
-
-<pre>
-  cd spree_digital
-  bundle install
-</pre>
-
-Bring up the test application (you only need to do this whenever you fiddle around with the migrations) and then you can run the tests as you please.
-
-<pre>
-  rake test_app
-  rake spec
-</pre>

+# Spree Digital
+
+This is a spree extension to enable downloadable products (ebooks, MP3s, videos, etc).
+
+The master branch is compatible with Spree 1.2.x. 1.0.x - 1.1.x versions are available, check the `Versionfile`.
+
+This documentation is not complete and possibly out of date in some cases. There are features that have been implemented that are not documented here, please look at the source for complete documentation.
+
+The idea is simple. You attach a file to a Product (or a Variant of this Product) and when people buy it, they will receive a link via email where they can download it once. There are a few assumptions that spree_digital (currently) makes and it's important to be aware of them. 
+
+* The table structure of spree_core is not touched. Spree digital lives parallel to spree_core and does change the existing database, except adding two new tables.
+* The download links will be sent via email in the order confirmation (or "resend" from the admin section). The links do *not* appear in the order "overview" that the customer sees. Adding download buttons to `OrdersController#show` is easy, [check out this gist](https://gist.github.com/3187793#file_add_spree_digital_buttons_to_invoice.rb).
+* Once the order is checked-out, the download links will immediately be sent (i.e. in the order confirmation). You'll have to modify the system to support 'delayed' payments (like a billable account).
+* You should create a ShippingMethod based on the Digital Delivery calculator type. The default cost for digital delivery is 0, but you can define a flat rate (creating a per-item digital delivery fee would be possible as well). Checkout the [source code](https://github.com/halo/spree_digital/blob/master/app/models/spree/calculator/digital_delivery.rb) for the Digital Delivery calculator for more information.
+* One may buy several items of the same digital product in one cart. The customer will simply receive several links by doing so. This allows customer's to legally purchase multiple copies of the same product and maybe give one away to a friend.
+* You can set how many times (clicks) the users downloads will work. You can also set how long the users links will work (expiration). For more information, [check out the preferences object](https://github.com/halo/spree_digital/blob/master/lib/spree/spree_digital_configuration.rb)
+* The file `views/order_mailer/confirm_email.text.erb` is the only thing that should need customization. If you are looking for HTML emails, [this branch of spree-html-email](http://github.com/iloveitaly/spree-html-email) supports spree_digital
+* A purchased product can be downloaded even if you disable the product immediately. You would have to remove the attached file in your admin section to prevent people from downloading purchased products.
+* File are uploaded to `rails_root/private`. Make sure it's symlinked in case you're using Capistrano. If you want to change the upload path, [check out this gist](https://gist.github.com/3187793#file_spree_digital_path_change_decorator.rb)
+* You must add a `views/spree/digitals/unauthorized.html.erb` file to customize an error message to the user if they exceed the download / days limit
+* We use send_file to send the files on download. See below for instructions on how to push file downloading off to nginx.
+
+## Installation
+
+Add this line to your gemfile:
+
+```shell
+gem 'spree_digital', :git => 'git://github.com/dlage/spree_digital.git', :branch => 'master'
+```
+
+The following terminal commands will copy the migration files to the corresponding directory in your Rails application and apply the migrations to your database.
+
+```shell
+bundle exec rails g spree_digital:install
+bundle exec rake db:migrate
+```
+
+Then set any preferences.
+
+### Shipping Configuration
+
+You should create a ShippingMethod based on the Digital Delivery calculator type. It will be detected by `spree_digital`. Otherwise your customer will be forced to choose something like "UPS" even if they purchase only downloadable products.
+
+### Improving File Downloading: `send_file` + nginx
+
+Without customization, all file downloading will route through the rails stack. This means that if you have two workers, and two customers are downloading files, your server is maxed out and will be unresponsive until the downloads have finished.
+
+Luckily there is an easy way around this: pass off file downloading to nginx (or apache, etc). Take a look at [this article](http://blog.kiskolabs.com/post/637725747/nginx-rails-send-file) for a good explanation.
+
+```
+# in your app's source
+# config/environments/production.rb
+
+# Specifies the header that your server uses for sending files
+# config.action_dispatch.x_sendfile_header = "X-Sendfile" # for apache
+config.action_dispatch.x_sendfile_header = 'X-Accel-Redirect' # for nginx
+
+
+# on your server
+# /etc/nginx/sites-available/spree-secure
+upstream unicorn_spree_secure {
+  server unix:/data/spree/shared/sockets/unicorn.sock fail_timeout=0;
+}
+
+server {
+  listen 443;
+  ...
+
+  location / {
+    proxy_set_header X_FORWARDED_PROTO https;
+    ... 
+
+    proxy_set_header X-Sendfile-Type  X-Accel-Redirect;
+    proxy_set_header X-Accel-Mapping  /data/spree/shared/uploaded-files/digitals/=/digitals/;
+    
+    ...
+  }
+
+  location /digitals/ {
+    internal;
+    root /data/spree/shared/uploaded-files/;
+  }
+  
+  ...
+
+}
+
+```

+## Usage
+
+### Table Diagram
+
+<img src="http://github.com/halo/spree_digital/raw/master/doc/tables.png">
+
+### Installation
+
+Get the spree framework and spree_digital extension for it:
+
+```shell
+git clone git://github.com/spree/spree.git
+git clone git://github.com/dlage/spree_digital.git
+```
+
+Go into the spree directory and run the bundle command:
+
+```shell
+cd spree
+bundle install
+```
+
+Go into the spree_digital directory and do the same:
+
+NOTE: At this point you may need to uncomment the stuff in the `Gemfile`  before you can start developing and testing!
+
+```shell
+cd spree_digital
+bundle install
+```
+
+Bring up the test application (you only need to do this whenever you fiddle around with the migrations) and then you can run the tests as you please.
+
+```shell
+rake test_app
+rake spec
+```
