+[![Build Status](https://travis-ci.org/rpless/cover-codecov.svg?branch=master)](https://travis-ci.org/rpless/cover-codecov)
+[![codecov.io](https://codecov.io/github/rpless/cover-codecov/coverage.svg?branch=master)](https://codecov.io/github/rpless/cover-codecov?branch=master)
+
+Adds [Codecov](https://codecov.io/) support to [Cover](https://github.com/florence/cover).
+
+_Note_: [Travis CI](https://travis-ci.org/) is currently the only supported method of posting data to [Codecov](https://codecov.io/).
+
+## Use with TravisCI
+First enable your repository on Travis and Codecov.
+Next add `cover-codecov` to the `build-deps` of your `info.rkt`.
+Then create a `.travis.yml` in the root of your repository.
+
+```yml
+# .travis.yml
+langauge: c
+sudo: false
+env:
+  global:
+    - RACKET_DIR=~/racket
+  matrix:
+    - RACKET_VERSION=6.2 # Set this to the version of racket you use
+
+before_install: # Install Racket
+  - git clone https://github.com/greghendershott/travis-racket.git ../travis-racket
+  - cat ../travis-racket/install-racket.sh | bash
+  - export PATH="${RACKET_DIR}/bin:${PATH}"
+
+install: raco pkg install --deps search-auto $TRAVIS_BUILD_DIR # install dependencies
+
+script:
+  - raco test $TRAVIS_BUILD_DIR # run tests. you wrote tests, right?
+
+after_success:
+  - raco cover -f codecov -d $TRAVIS_BUILD_DIR/coverage . # generate coverage information for coveralls
+```
+The above Travis configuration will install any project dependencies, test your project, and report coverage information to Codecov.
+
+For additional Travis configuration information look at [Travis Racket](https://github.com/greghendershott/travis-racket).
