+### Setup and teardown methods
+
+You can define a setup method that will be executed the first time a provider is rented and a teardown method
+that will be executed before the rental is done. This is useful when you want to avoid doing the same work
+multiple times when running multiple tasks on the same provider.
+
+```ts
+// I want to upload a big file to each provider only once
+const setup: LifecycleFunction = async (exe) => exe.uploadFile("./big-file.txt", "/golem/work/big-file.txt");
+
+// I want to remove the file after I'm done
+const teardown: LifecycleFunction = async (exe) => exe.run("rm /golem/work/big-file.txt");
+
+const pool = await glm.manyOf({
+  order,
+  concurrency,
+  setup,
+  teardown,
+});
+```
