+### Excluding Transitive Dependencies
+
+To exclude a transitive dependency from a Scala CLI project use the `exclude` parameter:
+
+- `exclude=org%%name` - for Scala modules
+- `exclude=org%name` - for Java modules
+
+It requires passing the organization and module name of the dependency to be excluded. For example, let's say you have
+the following Scala code:
+
+```scala title=Main.scala
+//> using dep "com.lihaoyi::pprint:0.8.1"
+object Main extends App {
+  println("Hello")
+}
+```
+
+If you want to compile it with the `pprint` library but exclude its `sourcecode` dependency, you can use
+the `exclude` parameter as follows:
+
+```scala title=Main.scala
+//> using dep "com.lihaoyi::pprint:0.8.1,exclude=com.lihaoyi%%sourcecode"
+object Main extends App {
+  println("Hello")
+}
+```
+
+To exclude Scala modules, you can also use a single `%` but with the full name of the module name, like this:
+
+```scala title=Main.scala
+//> using dep "com.lihaoyi::pprint:0.8.1,exclude=com.lihaoyi%sourcecode_3"
+object Main extends App {
+  println("Hello")
+}
+```
+
+
+### Dependency classifiers
+
+To specify a classifier of a dependency in a Scala CLI project, use the `classifier` parameter:
+
+- `classifier={classifier_name}`
+
+If you want to use the `pytorch` dependency with the classifier `linux-x86_64`, use the `classifier` parameter as follows:
+
+```scala title=Main.scala
+//> using dep "org.bytedeco:pytorch:1.12.1-1.5.8,classifier=linux-x86_64"
+object Main extends App {
+  println("Hello")
+}
+```

 ## Specifying dependencies from the command line
 
 You can add dependencies on the command line, with the `--dependency` option:

-## Updating dependencies

-To check if dependencies in using directives are up-to-date, use `dependency-update` command:
