+# This workflow will build a golang project for Gitea Actions
+# For more information see: https://docs.gitea.com/usage/actions/overview
+#
+# NOTE: All builds use CGO_ENABLED=0 since p8k library uses purego (not CGO)
+#       The library dynamically loads libsecp256k1 at runtime via purego
+#
+# Release Process:
+# 1. Update the version in the pkg/version/version file (e.g. v1.2.3)
+# 2. Create and push a tag matching the version:
+#    git tag v1.2.3
+#    git push origin v1.2.3
+# 3. The workflow will automatically:
+#    - Build binaries for Linux AMD64
+#    - Create a Gitea release with the binaries
+#    - Generate checksums
