+# log
 
-PostgreSQL back end for the `log` library suite.
+[![Hackage version](https://img.shields.io/hackage/v/log-base.svg?label=Hackage)](https://hackage.haskell.org/package/log-base)
+[![Build Status](https://github.com/scrive/log/workflows/Haskell-CI/badge.svg?branch=master)](https://github.com/scrive/log/actions?query=branch%3Amaster)
+
+A set of libraries that provide a way to record structured log messages with
+multiple backends.
+
+Supported backends:
+
+* Standard output via
+  [`log-base`](https://hackage.haskell.org/package/log-base).
+* Elasticsearch via
+  [`log-elasticsearch`](https://hackage.haskell.org/package/log-elasticsearch).
+* PostgreSQL via
+  [`log-postgres`](https://hackage.haskell.org/package/log-postgres).
+
+## Example
+
+A sample usage for logging to both standard output and Elasticsearch:
+
+```haskell
+{-# LANGUAGE OverloadedStrings #-}
+module Main where
+
+import Log
+import Log.Backend.ElasticSearch
+import Log.Backend.StandardOutput
+
+main :: IO ()
+main = do
+  let config = defaultElasticSearchConfig
+        { esServer = "http://localhost:9200"
+        , esIndex  = "logs"
+        }
+  withStdOutLogger $ \stdoutLogger -> do
+    withElasticSearchLogger config $ \esLogger -> do
+      runLogT "main" (stdoutLogger <> esLogger) defaultLogLevel $ do
+        logInfo_ "Hi there"
+```
