+## Crate Configuration `Cargo.toml`
+
+The Polkadot SDK uses many conventions when configuring a crate. Watch out for these things when you
+are creating a new crate.
+
+### Is the Crate chain-specific?
+
+Chain-specific crates, for example
+[`bp-bridge-hub-rococo`](https://github.com/paritytech/polkadot-sdk/blob/4014b9bf2bf8f74862f63e7114e5c78009529be5/bridges/chains/chain-bridge-hub-rococo/Cargo.toml#L10-L11)
+, should not be released as part of the Polkadot-SDK umbrella crate. We have a custom metadata
+attribute that is picked up by the [generate-umbrella.py](../../scripts/generate-umbrella.py)
+script, that should be applied to all chain-specific crates like such:
+
+```toml
+[package]
+# Other stuff...
+
+[package.metadata.polkadot-sdk]
+exclude-from-umbrella = true
+
+# Other stuff...
+```
+
+### Is the Crate a Test, Example or Fuzzer?
+
+Test or example crates, like
+[`pallet-example-task`](https://github.com/paritytech/polkadot-sdk/blob/9b4acf27b869d7cbb07b03f0857763b8c8cc7566/substrate/frame/examples/tasks/Cargo.toml#L9)
+, should not be released to crates.io. To ensure this, you must add `publish = false` to your
+crate's `package` section:
+
+```toml
+[package]
+# Other stuff...
+
+publish = false
+
+# Other stuff...
+```
+
 ## Helping out

+doc:
+  - audience: Runtime Dev
+    description: |
+      The `polkadot-sdk` umbrella crate does now not contain chain-specific crates. The reasoning is
+      that the SDK should be mostly chain-agnostic. Please check out
+      [psvm](https://github.com/paritytech/psvm) to select matching version numbers for chain-
+      specific crates.
