+# Contribution Guide
+
+:tada: Thanks for taking the time to contribute! :tada:
+
+The following is a set of guidelines for contributing to this repository, which is hosted in the [Codecov Organization](https://github.com/codecov) on GitHub. 
+
+## What does this repo do?
+
+This repo is a GitHub Action, meaning it integrates with the GitHub Actions CI/CD pipeline. It's meant to take formatted reports with code coverage stats and upload them to codecov.io. Our Node action uses the Actions toolkit to make system calls that allow us to run Codecov's bash uploader inside of Node. Essentially what we're doing in this action is downloading Codecov's bash uploader script from codecov.io/bash, saving it as a file in the current directory, executing the file via `exec` calls, then removing the script from the current directory. 
+
+## PRs, Issues, and Support
+
+Feel free to clone, modify code and request a PR to this repository. All PRs and issues will be reviewed by the Codecov team. If your PR/issue has been sitting for a while or if you have any questions, ping us at support@codecov.io

 # Codecov GitHub Action
-### Easily upload coverage reports to Codecov from Github Actions 
+
+[![GitHub Marketplace](https://img.shields.io/badge/Marketplace-v1-undefined.svg?logo=github&logoColor=white&style=flat)](https://github.com/marketplace/actions/codecov)
+[![FOSSA Status](https://app.fossa.com/api/projects/git%2Bgithub.com%2Fcodecov%2Fcodecov-action.svg?type=shield)](https://app.fossa.com/projects/git%2Bgithub.com%2Fcodecov%2Fcodecov-action?ref=badge_shield)
+### Easily upload coverage reports to Codecov from GitHub Actions
+
+>The latest release of this Action adds support for tokenless uploads from GitHub Actions!
 
 ## Usage
 
+To integrate Codecov with your Actions pipeline, specify the name of this repository with a tag number (`@v1` is recommended) as a `step` within your `workflow.yml` file.
+
+If you have a *private repository*, this Action also requires you to [provide an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) from [codecov.io](https://www.codecov.io) (tip: in order to avoid exposing your token, store it as a `secret`). Optionally, you can choose to include up to four additional inputs to customize the upload context. **For public repositories, no token is needed**
+
 Inside your `.github/workflows/workflow.yml` file:
 
 ```yaml
 steps:
 - uses: actions/checkout@master
-- uses: actions/codecov-action@v0.2
+- uses: codecov/codecov-action@v1
   with:
-    token: ${{secrets.CODECOV_TOKEN}}
+    token: ${{ secrets.CODECOV_TOKEN }} # not required for public repos
+    files: ./coverage1.xml,./coverage2.xml # optional
+    flags: unittests # optional
+    name: codecov-umbrella # optional
+    fail_ci_if_error: true # optional (default = false)
+    verbose: true # optional (default = false)
 ```
->**Note**: This assumes that you've set your Codecov token inside settings > secrets as `CODECOV_TOKEN`. If not, you can get an upload token for your specific repo on codecov.io. A token is not required for public repositories. 
+>**Note**: This assumes that you've set your Codecov token inside *Settings > Secrets* as `CODECOV_TOKEN`. If not, you can [get an upload token](https://docs.codecov.io/docs/frequently-asked-questions#section-where-is-the-repository-upload-token-found-) for your specific repo on [codecov.io](https://www.codecov.io). Keep in mind that secrets are *not* available to forks of repositories.
 
 ## Arguments
 
-| Argument  | Description |
-| :---:     |     :---:   | 
-| `token`  | Used to authorize coverage report uploads  |
+Codecov's Action currently supports five inputs from the user: `token`, `file`, `flags`,`name`, and `fail_ci_if_error`. These inputs, along with their descriptions and usage contexts, are listed in the table below:
+
+| Input  | Description | Usage |
+| :---:     |     :---:   |    :---:   |
+| `token`  | Used to authorize coverage report uploads  | *Required for private repos* |
+| `files`  | Comma-separated paths to the coverage report(s) | Optional
+| `directory` | Directory to search for coverage reports. | Optional
+| `flags`  | Flag the upload to group coverage metrics (unittests, uitests, etc.). Multiple flags are separated by a comma (ui,chrome) | Optional
+| | |
+| `aws_curl_args` | Extra curl arguments to communicate with AWS. | Optional
+| `codecov_curl_args` | Extra curl arguments to communicate with Codecov. e.g., -U "--proxy http://http-proxy" | Optional
+| `commit_parent` | The commit SHA of the parent for which you are uploading coverage. If not present, the parent will be determined using the API of your repository provider.  When using the repository provider's API, the parent is determined via finding the closest ancestor to the commit. | Optional
+| `env_vars`  | Environment variables to tag the upload with. Multiple env variables can be separated with commas (e.g. `OS,PYTHON`) | Optional
+| `fail_ci_if_error`  | Specify if CI pipeline should fail when Codecov runs into errors during upload. *Defaults to **false*** | Optional
+| `functionalities` | Toggle functionalities | Optional
+| | `coveragepy` Disable python coverage |
+| | `fix` Disable report fixing |
+| | `gcov` Disable gcov |
+| | `gcovout` Disable gcov output |
+| | `html` Enable coverage for HTML files |
+| | `network` Disable uploading the file network |
+| | `recursesubs` Enable recurse submodules in git projects when searching for source files | |
+| | `search` Disable searching for reports |
+| | `xcode` Disable xcode processing |
+| `gcov_path_include` | Paths to include during gcov gathering (as a glob) | Optional
+| `gcov_args` | extra arguments to pass to gcov | Optional
+| `gcov_executable` | gcov executable to run. Defaults to 'gcov' | Optional
+| `gcov_path_exclude` | Paths to ignore during gcov gathering (as a glob) | Optional
+| `gcov_prefix` | Prefix filepaths to help resolve path fixing | Optional
+| `gcov_root_dir` | Project root directory, also used when preparing gcov | Optional
+| `move_coverage_to_trash` | Move discovered coverage reports to the trash | Optional
+| `name`  | Custom defined name for the upload | Optional
+| `override_branch` | Specify the branch name | Optional
+| `override_build` | Specify the build number | Optional
+| `override_commit` | Specify the commit SHA | Optional
+| `override_pr` | Specify the pull request number | Optional
+| `override_tag` | Specify the git tag | Optional
+| `path_to_write_report` | Write upload file to path before uploading | Optional
+| `root_dir` | Used when not in git/hg project to identify project root directory | Optional
+| `verbose` | Specify whether the Codecov output should be verbose | Optional
+| `working-directory` | Directory in which to execute `codecov.sh` | Optional
+| `xcode_derived_data` | Custom Derived Data Path for Coverage.profdata and gcov processing | Optional
+| `xcode_package` | Specify packages to build coverage. Uploader will only build these packages. This can significantly reduces time to build coverage reports. -J 'MyAppName' Will match "MyAppName" and "MyAppNameTests" -J '^ExampleApp$' Will match only "ExampleApp" not "ExampleAppTests" | Optional
