+  @moduledoc """
+  Facilities for managing a cluster of slave VM's for federated testing.
+
+  ## Spawning the federated cluster
+
+  `spawn_cluster/1` spawns a map of slave nodes that are started
+  within the running VM. During startup, the slave node is sent all configuration
+  from the parent node, as well as all code. After receiving configuration and
+  code, the slave then starts all applications currently running on the parent.
+  The configuration passed to `spawn_cluster/1` overrides any parent application
+  configuration for the provided OTP app and key. This is useful for customizing
+  the Ecto database, Phoenix webserver ports, etc.
+
+  For example, to start a single federated VM named ":federated1", with the
+  Pleroma Endpoint running on port 4123, and with a database named
+  "pleroma_test1", you would run:
+
+    endpoint_conf = Application.fetch_env!(:pleroma, Pleroma.Web.Endpoint)
+    repo_conf = Application.fetch_env!(:pleroma, Pleroma.Repo)
+
+    Pleroma.Cluster.spawn_cluster(%{
+      :"federated1@127.0.0.1" => [
+        {:pleroma, Pleroma.Repo, Keyword.merge(repo_conf, database: "pleroma_test1")},
+        {:pleroma, Pleroma.Web.Endpoint,
+        Keyword.merge(endpoint_conf, http: [port: 4011], url: [port: 4011], server: true)}
+      ]
+    })
+
+  *Note*: application configuration for a given key is not merged,
+  so any customization requires first fetching the existing values
+  and merging yourself by providing the merged configuration,
+  such as above with the endpoint config and repo config.
+
+  ## Executing code within a remote node
+
+  Use the `within/2` macro to execute code within the context of a remote
+  federated node. The code block captures all local variable bindings from
+  the parent's context and returns the result of the expression after executing
+  it on the remote node. For example:
+
+      import Pleroma.Cluster
+
+      parent_value = 123
+
+      result =
+        within :"federated1@127.0.0.1" do
+          {node(), parent_value}
+        end
+
+      assert result == {:"federated1@127.0.0.1, 123}
+
+  *Note*: while local bindings are captured and available within the block,
+  other parent contexts like required, aliased, or imported modules are not
+  in scope. Those will need to be reimported/aliases/required within the block
+  as `within/2` is a remote procedure call.
