-### MongoDB 4.0 Transactions
-
-As of version 4 MongoDB supports [Transactions](https://www.mongodb.com/transactions). Transactions are built on top of
- `ClientSessions` and therefore require an active session.
-
-`MongoTransactionManager` is the gateway to the well known Spring transaction support. It allows applications to use 
-[managed transaction features of Spring](http://docs.spring.io/spring/docs/current/spring-framework-reference/html/transaction.html).
-The `MongoTransactionManager` binds a `ClientSession` to the thread. `MongoTemplate` automatically detects those and operates on them accordingly.
-
-```java
-@Configuration
-static class Config extends AbstractMongoConfiguration {
-
-	@Bean
-	MongoTransactionManager transactionManager(MongoDbFactory dbFactory) {
-		return new MongoTransactionManager(dbFactory);
-	}
-
-	// ...
-}

-@Component
-public class StateService {

-	void someBusinessFunction(Step step) {

-# Benchmarks
-
-Benchmarks are based on [JMH](http://openjdk.java.net/projects/code-tools/jmh/).
-
-# Running Benchmarks
-
-Running benchmarks is disabled by default and can be activated via the `benchmarks` profile.
-To run the benchmarks with default settings use.
-
-```bash
-mvn -P benchmarks clean test
-```
-
-A basic report will be printed to the CLI.
-
-```bash
-# Run complete. Total time: 00:00:15
-
-Benchmark                                    Mode  Cnt        Score       Error  Units
-MappingMongoConverterBenchmark.readObject   thrpt   10  1920157,631 ± 64310,809  ops/s
-MappingMongoConverterBenchmark.writeObject  thrpt   10   782732,857 ± 53804,130  ops/s
-```
-
-## Running all Benchmarks of a specific class
-
-To run all Benchmarks of a specific class, just provide its simple class name via the `benchmark` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark
-```
-
-## Running a single Benchmark
-
-To run a single Benchmark provide its containing class simple name followed by `#` and the method name via the `benchmark` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D benchmark=MappingMongoConverterBenchmark#readObjectWith2Properties
-```
-
-# Saving Benchmark Results
-
-A detailed benchmark report is stored in JSON format in the `/target/reports/performance` directory.
-To store the report in a different location use the `benchmarkReportDir` command line argument.
-
-## MongoDB
-
-Results can be directly piped to MongoDB by providing a valid [Connection String](https://docs.mongodb.com/manual/reference/connection-string/) via the `publishTo` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D publishTo=mongodb://127.0.0.1:27017
-```
-
-NOTE: If the uri does not explicitly define a database the default `spring-data-mongodb-benchmarks` is used. 
-
-## HTTP Endpoint
-
-The benchmark report can also be posted as `application/json` to an HTTP Endpoint by providing a valid URl via the `publishTo` command line argument.
-
-```bash
-mvn -P benchmarks clean test -D publishTo=http://127.0.0.1:8080/capture-benchmarks
-```
-
-# Customizing Benchmarks
-
-Following options can be set via command line.
-
-Option | Default Value
---- | ---
-warmupIterations | 10
-warmupTime | 1 (seconds)
-measurementIterations | 10
-measurementTime | 1 (seconds)
-forks | 1
-benchmarkReportDir | /target/reports/performance (always relative to project root dir)
-benchmark | .* (single benchmark via `classname#benchmark`)
-publishTo | \[not set\] (mongodb-uri or http-endpoint)

+# MongoDB Log4J Appender
+
+This module sets up a Log4J appender that puts logging events in MongoDB. It is fully configurable
+and connects directly to the MongoDB server using the driver. It has no dependency on any Spring package.
+
+To use it, configure a host, port, (optionally) applicationId, and database property in your Log4J configuration:
+
+    log4j.appender.stdout=org.springframework.data.mongodb.log4j.MongoLog4jAppender
+    log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
+    log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - <%m>%n
+    log4j.appender.stdout.host = localhost
+    log4j.appender.stdout.port = 27017
+    log4j.appender.stdout.database = logs
+    log4j.appender.stdout.collectionPattern = %c
+    log4j.appender.stdout.applicationId = my.application
+    log4j.appender.stdout.warnOrHigherWriteConcern = FSYNC_SAFE
+
+It will even support properties in your MDC (so long as they're Strings or support .toString()).
+
+The collection name is configurable as well. If you don't specify anything, it will use the Category name.
+If you want to specify a collection name, you can give it a Log4J pattern layout format string which will have
+the following additional MDC variables in the context when the collection name is rendered:
+
+    "year" = Calendar.YEAR
+    "month" = Calendar.MONTH + 1
+    "day" = Calendar.DAY_OF_MONTH
+    "hour" = Calendar.HOUR_OF_DAY
+    "applicationId" = configured applicationId
+
+An example log entry might look like:
+
+    {
+      "_id" : ObjectId("4d89341a8ef397e06940d5cd"),
+      "applicationId" : "my.application",
+      "name" : "org.springframework.data.mongodb.log4j.MongoLog4jAppenderIntegrationTests",
+      "level" : "DEBUG",
+      "timestamp" : ISODate("2011-03-23T16:53:46.778Z"),
+      "properties" : {
+        "property" : "one"
+      },
+      "message" : "DEBUG message"
+    }
+
+To set WriteConcern levels for WARN or higher messages, set warnOrHigherWriteConcern to one of the following:
+
+* FSYNC_SAFE
+* NONE
+* NORMAL
+* REPLICAS_SAFE
+* SAFE
