+# Try Runtime GHA
+
+Try Runtime GHA makes it easy to add [try-runtime](https://paritytech.github.io/try-runtime-cli/try_runtime/) checks to your CI.
+
+## Motivation
+
+`try-runtime` enforces critical invariants such as:
+
+- Migrations execute correctly, including `pre_upgrade` and `post_upgrade` hooks
+- Migration execution does not exceed the block weight limit
+- Migrations are idempotent
+- Try State invariants pass
+- Post-Migration, all runtime state is decodable
+
+Given that code changes can break any of the above invariants, running `try-runtime` checks is as important as regularly running cargo tests in your PR CI, to prevent accidental regressions.
+
+## Usage
+
+Create a new [Github Action Workflow](https://docs.github.com/en/actions/using-workflows).
+
+The simplest usage only requires two parameters `runtime-package`, and `node-uri`:
+
+```yaml
+name: Check Migrations
+
+on:
+  push:
+    branches: ["main"]
+  pull_request:
+jobs:
+  check-migrations:
+    steps:
+      - name: Checkout sources
+        uses: actions/checkout@v3
+
+      - name: Run Polkadot Try Runtime Checks
+        uses: "paritytech/try-runtime-gha@main"
+        with:
+          runtime-package: "my-runtime"
+          node-uri: "wss://my-runtime-uri:443"
+```
+
+When triggered, the GHA will
+
+1. Build the `runtime-package` with flags `--production` and `--features try-runtime`
+2. Download [try-runtime-cli](https://github.com/paritytech/try-runtime-cli)
+3. Exec `try-runtime on-runtime-upgrade --checks [checks] [extra-args] live [node-uri]
+
+If there is an error, you can check the logs for the exact command that failed to help reproduce the issue in your local environment.
+
+See more examples at [`.github/workflows/examples.yml`](https://github.com/paritytech/try-runtime-gha/blob/main/.github/workflows/examples.yml).
