+# Note to Code Shelter maintainers
+
+The `multi-geth` project is an extension of upstream
+[go-ethereum](https://github.com/ethereum/go-ethereum) that add more
+blockchain network support. Some philosophical notes to maintainers:
+
+* We accept all patches to add new network supports, as long as it's
+  reasonable. In other words, we don't reject new network supports due
+  to political reasons.
+* We follow upstream closely.
+
+Besides checking out new PR to merge, please also help out following
+upstream and making new releases. Thank you!
+
+## Merge Upstream Changes
+
+Add `https://github.com/ethereum/go-ethereum` to one of your
+remote. Then pull the upstream `master` branch (note that it must be
+`master` branch!), resolve conflicts and create a new PR.
+
+When you review a merge-upstream PR, please make sure it is merged via
+a merge commit.
+
+## Making New Releases
+
+Whenever the upstream makes a new release, multi-geth usually makes a
+new release as well. Besides, new releases can also be made when a
+notable new feature is added in multi-geth.
+
+To create a new release, branch off `master` into a release branch
+`release/vx.x.x`. Change `VersionMeta` to `stable` in
+`params/version.go`. Create a **signed commit** and push it to this
+repo. The CI will them automatically build all release binaries. After
+all binaries are built, create a Github release on that tag.
