+# Release Process
+
+This document outlines the process for releasing a new version of the Nibiru binary.
+
+## Step 1) Create a new release branch off master
+
+```sh
+git checkout master
+git branch releases/v0.x.y
+git switch releases/v0.x.y
+```
+
+## Step 2) Update the changelog
+
+- Move the changelog notes from `Unreleased` to a new section titled `v0.x.y`
+- Add the date to `v0.x.y`
+
+## Step 3) Create a tag
+
+```sh
+git tag -a -s -m "Create new release v0.x.y" v0.x.y
+git push origin v0.x.y
+```
+
+## Step 4) Go to the [GitHub Releases](https://github.com/NibiruChain/nibiru/releases) page
+
+- Create a new release from the tag v0.x.y you just pushed
+- Make sure you save the release as a draft release
+- Make sure you check the `This is a pre-release` checkbox
+
+## Step 5) Build the binaries locally
+
+```sh
+cd nibiru/
+
+ignite chain build --release -t linux:amd64 -t linux:arm64 -t darwin:amd64 -t darwin:arm64
+```
+
+## Step 6) Upload the files in the release/ directory to GitHub
+
+Upload all the files under `releases/` to the [GitHub Release](https://github.com/NibiruChain/nibiru/releases) you just made
+
+## Step 7) Merge your release branch into master
+
+After merging the release branch `releases/v0.x.y` into master, uncheck the `This is a pre-release` checkbox for the release.
