+## Options
+
+Additional command line options for Goreleaser can be set using the `GORELEASER_EXTRA_ARGS` argument. These will be appended to the arguments for `goreleaser release`.
+
+## Out-of-Memory Issues
+
+If you're experiencing OOM kills during the Gorelease build, consider using a bigger runner by updating the `tags` on the `goreleaser` job. It may also help to reduce paralellism in the Goreleaser build tool.
+
+This can be done as follows:
+
+```yaml
+goreleaser:
+  tags: [saas-linux-medium-amd64]
+  variables:
+    GORELEASER_EXTRA_ARGS: "-p 1"
+```
