In just a few steps, you’ll create two stacked pull requests using mg and see them on mrge.io (or GitHub).

​
Quick installation (macOS)

brew install mrge-io/homebrew-tap/mg

If you’re not on macOS or need detailed instructions, see the full installation guide.

​
1) Initialize & set up

cd /path/to/your-repo
mg init

This tells mg which branch is your trunk (main or master).

Authentication: If you’re not already logged in, mg may prompt you for a GitHub personal access token or use the GitHub CLI (gh) for OAuth.

​
2) Build your first stack

1

Check out trunk

mg checkout main

Make sure you’re on the trunk branch.

2

Create the first branch

mg branch feature_1
mg list

You should see:

main
 └─ feature_1
3

Write code & commit

mg add . && mg commit -m "My commit message"

(Or use normal Git commands—unrecognized subcommands pass through to Git.)

4

Add a second branch

mg branch feature_2
mg add . && mg commit -m "Another commit"
mg list

Now:

main
 └─ feature_1
    └─ feature_2
5

Push your stack to remote

mg push

By default, mg opens a text editor to let you tweak each PR’s title/description.

mg push --all pushes every branch at once.

If you push a child branch before its parent, mg may fail (the parent PR doesn’t exist on remote yet).

6

Check your PRs

Now each branch has an associated PR on mrge.io or GitHub. Open the UI to see them stacked. You’ve created a basic stacked workflow for your features!
