+
+A GitHub Action that reads Cobertura format code coverage files from your test suite and outputs a text or markdown summary. This summary can be posted as a Pull Request comment or included in Release Notes by other actions to give you an immediate insight into the health of your code without using a third-party site.
+
+Code Coverage Summary is designed for use with [Coverlet](https://github.com/coverlet-coverage/coverlet) and [gcovr](https://github.com/gcovr/gcovr) but it should work with any test framework that outputs coverage in Cobertura format. If it doesn't work with your tooling please [open an issue][new-issue] to discuss the problem.
+
+As a Docker based action Code Coverage Summary requires a Linux runner, see [Types of Action](https://docs.github.com/en/actions/creating-actions/about-custom-actions#types-of-actions). If you need to build with a Windows or MacOS runner a workaround would be to upload the coverage file as an artifact and use a separate job with a Linux runner to generate the summary.
 
-Written for use with [Coverlet](https://github.com/coverlet-coverage/coverlet) and .Net but it should work with any tests that output coverage in Cobertura format.
 
 ## Inputs
 
-#### `filename`
+### `filename`
 **Required**
 
 Code coverage file to analyse.
 
+**v1.2.0-beta only:** A comma separated list of code coverage files to analyse.
+
 Note: Coverlet creates the coverage file in a random named directory (guid) so you need to copy it to a predictable path before running this Action, see the [.Net 5 Workflow Example](#net-5-workflow-example) below.
 
-#### `badge`
+
+### `badge`
 
 Include a badge reporting the Line Rate coverage in the output using [shields.io](https://shields.io/) - `true` or `false` (default).
 
-If the overall Line Rate is less than 50% the badge will be red, if it is 50% - 74% it will be yellow and if it is 75% or over it will be green. 
+Line Rate | Badge
+--------- | -----
+less than lower threshold (50%) | ![Code Coverage](https://img.shields.io/badge/Code%20Coverage-45%25-critical?style=flat)
+between thresholds (50% - 74%) | ![Code Coverage](https://img.shields.io/badge/Code%20Coverage-65%25-yellow?style=flat)
+equal or greater than upper threshold (75%) | ![Code Coverage](https://img.shields.io/badge/Code%20Coverage-83%25-success?style=flat)
 
-#### `format`
+See [`thresholds`](#thresholds) to change these values.
+
+
+### `fail_below_min`
+
+Fail the workflow if the overall Line Rate is below lower threshold - `true` or `false` (default). The default lower threshold is 50%, see [`thresholds`](#thresholds).
+
+
+### `format`
 
 Output Format - `markdown` or `text` (default).
 
-#### `output`
+
+### `hide_branch_rate`
+**v1.2.0-beta only**
+
+Hide Branch Rate values in the output - `true` or `false` (default).
+
+
+### `hide_complexity`
+**v1.2.0-beta only**
+
+Hide Complexity values in the output - `true` or `false` (default).
+
+
+### `indicators`
+
+Include health indicators in the output - `true` (default) or `false`.
+
+Line Rate | Indicator
+--------- | ---------
+less than lower threshold (50%) | ❌
+between thresholds (50% - 74%) | ➖
+equal or greater than upper threshold (75%) | ✔

+
+
+### `output`
 
 Output Type - `console` (default), `file` or `both`.
 
@@ -33,30 +89,46 @@ Output Type - `console` (default), `file` or `both`.
 
 `both` will output the coverage summary to the Action log and a file as above.
 
+

+Lower and upper threshold percentages for badge and health indicators, lower threshold can also be used to fail the action. Separate the values with a space and enclose them in quotes; default `'50 75'`.
