 ## Features
@@ -152,29 +152,21 @@ This library offers the following features:
 Designed for discovery using your favorite IDE's auto-complete feature.
 The main entry points are:
 
-* [requireThat(value, name)](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements/java/DefaultJavaValidators.html#requireThat(T,java.lang.String)) for method preconditions.
-* [assumeThat(value, name)](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements/java/DefaultJavaValidators.html#assumeThat(T,java.lang.String)) for class invariants, method postconditions and private methods.
-* [checkIfThat(value, name)](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements/java/DefaultJavaValidators.html#checkIf(T,java.lang.String)) for multiple failures and customized error handling.
-* [JavaValidators](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements/java/JavaValidators.html) for custom configurations.
+* [requireThat(value, name)](https://cowwoc.github.io/requirements.java/10.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements10/java/DefaultJavaValidators.html#requireThat(T,java.lang.String))

+  for multiple failures and customized error handling.
 
-The first three methods use a shared configuration, while `JavaValidators` allows you to create an independent
-configuration.
+See the [API documentation](https://cowwoc.github.io/requirements.java/10.0/docs/api/) for more details.
 
-* `requireThat()` and `assumeThat()` throw an exception on the first validation failure.
-* `checkIf()` returns multiple validation failures at once. It is more flexible than the others, but its syntax
-is more verbose.
+## Best practices
 
-Thrown exceptions may be configured using [ConfigurationUpdater.exceptionTransformer(Function)](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/com.github.cowwoc.requirements.java/com/github/cowwoc/requirements/java/ConfigurationUpdater.html#exceptionTransformer(java.util.function.Function)).

-See the [API documentation](https://cowwoc.github.io/requirements.java/9.0.0/docs/api/) for more details.
-
-## Tips
-
-* Use `assert` with `assumeThat().elseThrow()` for sanity checks. When assertions are disabled, the checks will get removed.
 * Use `checkIf().elseGetMessages()` to return failure messages without throwing an exception.
   This is the fastest validation approach, ideal for web services.
-* To enhance the clarity of failure messages, you should provide parameter names, even when they are optional. 
-  In other words, favor `assumeThat(value, name)` to `assumeThat(value)`.
+* To enhance the clarity of failure messages, you should provide parameter names, even when they are optional.
