 ### Workflow inputs and secrets
 
 Basic compilation workflow path:  
 `stellar-expert/soroban-build-workflow/.github/workflows/release.yml@main`
 
 The workflow expects the following inputs in the `with` section:
-- `release_name` (required) - release name template that includes a release version variable, e.g. `${{ github.ref_name }}`
-- `package` (optional) - package name to build. Builds contract in working directory by default
-- `relative_path` (optional) - relative path to the contract source directory. Defaults to the repository root directory
-- `make_target` (optional) - make target to invoke. Not invoked by default. Useful for contracts with dependencies, that must be built before the main contract

+### Workflow permissions
+
+In order to create a release, the workflow needs `contents: write` permission. Default workflow permissions for a repository can be found at
+"Settings"->"Actions"->"Workflow permissions". This workflow should work just fine with default settings ("Read and write permissions").
+Alternatively, it's possible to specify permissions in the `.github/workflows/release.yml` configuration file itself:
+```yaml
+permissions:
+  contents: write
+```

 ### Building multiple contracts
 
 To build multiple contracts, add a separate job for each contract. The workflow will compile and release each contract independently.
