-# Runtimes
+# Paseo Releases
+> ⚠️ NOTE: These builds are provided for development purposes only!
 
-Work In Progress runtime for Paseo Polkadot community testnet.
+This repo provides cross-platform builds of the Paseo Network chain spec generator for usage with [`pop-cli`](https://github.com/r0gue-io/pop-cli) only.
 
-## Structure
+Builds are generated as per the release tags at https://github.com/paseo-network/runtimes, along with any Rust compiler version noted within the release notes of each release.
 
-```pre
-├── relay
-│   ├── paseo
-└── system-parachains
-    ├── asset-hub-paseo
-        ├── bp-asset-hub-paseo
-    ├── bridge-hub-paseo
-        ├── bp-bridge-hub-paseo
-```
+The [workflow](./.github/workflows/release.yml) generates the cross-platform binaries and creates a corresponding release with the same release tag. The corresponding commit hash is added to the release notes for additional verification.
+
+## Aura Signing Scheme
+This repo also overrides the signing scheme used for Aura by the `asset-hub-paseo-runtime` runtime to standardise on 
+SR25519 instead of ED25515 as found on Polkadot, easing integrations with SDK binaries and tooling.
+
+## Supported Platforms
+The currently supported platforms/targets are as follows:
+- Linux
+    - `aarch64-unknown-linux-gnu`
+    - `x86_64-unknown-linux-gnu`
