+# Deployment failed
+
+## Why This Error Occurred
+
+When deploying this project, there was not a successful deployment into the `READY` state.
+
+## How to Fix It
+
+This is a generic error to catch problems in the deployment. The error is likely to vary depending on the deployment and the conditions at the time.
+
+Try looking in the logs for information about the deployment and the failure, this could be done at (vercel.com)[https://vercel.com]. You can also use the `vc logs` command to display the build logs for the deployment.
+
+This might not be a permanent error and retrying the deployment might also resolve it.
