+ceedling-gcov
+=============
+
+Plugin for integrating GNU GCov code coverage tool into Ceedling projects.
+Currently only designed for the gcov command (like LCOV for example). In the
+future we could configure this to work with other code coverage tools.
+
+
+This plugin currently uses `gcovr` to generate HTML reports as a utility. The
+normal gcov plugin _must_ be run first for this report to generate.
+
+Gcovr can be installed via pip like so:
+
+```
+pip install gcovr
+```
+
+There are two types of gcovr HTML reports that can be configured in your
+`project.yml`. To create a basic HTML report with only the overall file
+information use the following config. 
+
+```
+:gcov:
+  :html_report_type: basic
+```
+To create a detailed HTML report with line by line breakdown of the coverage use
+the following config.
+
+```
+:gcov:
+  :html_report_type: detailed
+```
+
+These reports will be found in `build/artifacts/gcov`.
+
+
+
+# To-Do list
+
+- Generate overall report (combined statistics from all files with coverage)
+- Generate coverage output files
+- Easier option override for better customisation
