+# Code Coverage Summary Action
+
+A GitHub Action to analyse test code coverage in Cobertura format and output a summary.
+
+Written for use with [Coverlet](https://github.com/coverlet-coverage/coverlet) on .Net but it should work with any tests that output coverage in Cobertura format.
+
+## Inputs
+
+### `filename`
+
+**Required** Code coverage file 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 [.Net 5 Workflow Example](#net-5-workflow-example) below.
+
+### `badge`
+
+Include a badge in the output using [shields.io](https://shields.io/) - `true` or `false` (default).
+
+If code coverage is less than 50% the badge will be red, if coverage is 50% - 74% it will be yellow and if coverage is 75% or over it will be green. 
+
+### `format`
+
+Output Format - `markdown` or `text` (default).
+
+### `output`
+
+Output Type - `console` (default), `file` or `both`.
+
+`console` will output the coverage summary to the GitHub Action log.
+
+`file` will output the coverage summary to `code-coverage-results.txt` or `code-coverage-results.md` in the workflow's working directory.
+
+## Outputs
+
+Code coverage summary in plain text or markdown format to the console (action log) or a file.
+
+```
+Code Coverage File: coverage/coverage.cobertura.xml
+https://img.shields.io/badge/Code%20Coverage-77%25-success?style=flat
+Line Rate = 77%, Lines Covered = 1107 / 1433
+Branch Rate = 60%, Branches Covered = 321 / 532
+Complexity = 917
+Company.Example: Line Rate = 78%, Branch Rate = 60%, Complexity = 906
+Company.Example.Library: Line Rate = 27%, Branch Rate = 100%, Complexity = 11
