+Statusz-like page for Go
+========================
+
+This module adds a /debug/status handler to net/http that displays useful information for debug purposes in production.
+
+Basic Usage
+-----------
+
+For the basic status page, just include the module.
+
+```go
+import (
+ _ "github.com/q3k/statusz"
+)
+
+func main() {
+ http.ListenAndServe("127.0.0.1:6000", nil)
+}
+```
+
+Adding sections
+---------------
+
+To add a section to the status page, call `AddStatusSection` like so:
+
+```go
+import (
+ statusz "github.com/q3k/statusz"
+)
+
+
+func main() {
+ statusz.AddStatusPart("Worker Status", function(ctx context.Context) {
+ return fmt.Sprintf("%d workers alive", workerCount)
+ })
+ http.ListenAndServe("127.0.0.1:6000", nil)
+}
+```
+
+For custom section templates, call `AddStatusPart`, which accepts a http/template fragment that will be rendered on the result of the part render function.
