-# How to contribute
-
-## Things we will merge
-
-* Bugfixes
-* Performance improvements
-* Features that are likely to be useful to the majority of Liquid users
-
-## Things we won't merge
-
-* Code that introduces considerable performance degrations
-* Code that touches performance-critical parts of Liquid and comes without benchmarks
-* Features that are not important for most people (we want to keep the core Liquid code small and tidy)
-* Features that can easily be implemented on top of Liquid (for example as a custom filter or custom filesystem)
-* Code that does not include tests
-* Code that breaks existing tests
-
-## Workflow
-
-* Fork the Liquid repository
-* Create a new branch in your fork
-* If it makes sense, add tests for your code and/or run a performance benchmark
-* Make sure all tests pass (`bundle exec rake`)
-* Create a pull request

 ## Introduction
 
 Liquid is a template engine which was written with very specific requirements:
@@ -50,57 +41,4 @@ For standard use you can just pass it the content of a file and call render with
 @template.render('name' => 'tobi')                # => "hi tobi"
 ```
 
-### Error Modes
+[![Build Status](https://secure.travis-ci.org/Shopify/liquid.png)](http://travis-ci.org/Shopify/liquid)
-
-Setting the error mode of Liquid lets you specify how strictly you want your templates to be interpreted.
-Normally the parser is very lax and will accept almost anything without error. Unfortunately this can make
-it very hard to debug and can lead to unexpected behaviour. 
-
-Liquid also comes with a stricter parser that can be used when editing templates to give better error messages
-when templates are invalid. You can enable this new parser like this:
-
-```ruby
-Liquid::Template.error_mode = :strict # Raises a SyntaxError when invalid syntax is used
-Liquid::Template.error_mode = :warn # Adds errors to template.errors but continues as normal
-Liquid::Template.error_mode = :lax # The default mode, accepts almost anything.
-```
-
-If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
-```ruby
-Liquid::Template.parse(source, :error_mode => :strict)
-```
-This is useful for doing things like enabling strict mode only in the theme editor.
-
-It is recommended that you enable `:strict` or `:warn` mode on new apps to stop invalid templates from being created.
-It is also recommended that you use it in the template editors of existing apps to give editors better error messages.
-
-### Undefined variables and filters
-
-By default, the renderer doesn't raise or in any other way notify you if some variables or filters are missing, i.e. not passed to the `render` method.
-You can improve this situation by passing `strict_variables: true` and/or `strict_filters: true` options to the `render` method.
-When one of these options is set to true, all errors about undefined variables and undefined filters will be stored in `errors` array of a `Liquid::Template` instance.
-Here are some examples:
-
-```ruby
-template = Liquid::Template.parse("{{x}} {{y}} {{z.a}} {{z.b}}")
-template.render({ 'x' => 1, 'z' => { 'a' => 2 } }, { strict_variables: true })
-#=> '1  2 ' # when a variable is undefined, it's rendered as nil
-template.errors
-#=> [#<Liquid::UndefinedVariable: Liquid error: undefined variable y>, #<Liquid::UndefinedVariable: Liquid error: undefined variable b>]
-```
-
-```ruby
-template = Liquid::Template.parse("{{x | filter1 | upcase}}")
-template.render({ 'x' => 'foo' }, { strict_filters: true })
-#=> '' # when at least one filter in the filter chain is undefined, a whole expression is rendered as nil
-template.errors
-#=> [#<Liquid::UndefinedFilter: Liquid error: undefined filter filter1>]
-```
-
-If you want to raise on a first exception instead of pushing all of them in `errors`, you can use `render!` method:
-
-```ruby
-template = Liquid::Template.parse("{{x}} {{y}}")
-template.render!({ 'x' => 1}, { strict_variables: true })
-#=> Liquid::UndefinedVariable: Liquid error: undefined variable y
-```
