+# Gitea Mixin
+
+Gitea Mixin is a set of configurable Grafana dashboards based on the metrics exported by the Gitea built-in metrics endpoint.
+
+## Generate config files
+
+You can manually generate dashboards, but first you should install some tools:
+
+```bash
+go install github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb@latest
+go install github.com/google/go-jsonnet/cmd/jsonnet@latest
+# or in brew: brew install go-jsonnet
+```
+
+For linting and formatting, you would also need `mixtool` and `jsonnetfmt` installed. If you
+have a working Go development environment, it's easiest to run the following:
+
+```bash
+go install github.com/monitoring-mixins/mixtool/cmd/mixtool@latest
+go install github.com/google/go-jsonnet/cmd/jsonnetfmt@latest
+```
+
+The files in `dashboards_out` need to be imported
+into your Grafana server.  The exact details will be depending on your environment.
+
+Edit `config.libsonnet` if required and then build JSON dashboard files for Grafana:
+
+```bash
+make
+```
+
+For more advanced uses of mixins, see
+https://github.com/monitoring-mixins/docs.
