Yeah. Thx

Please use something else than "dev-master"

Master is a deprecated term/phrase. Following githubs naming here, "dev-main" would be an appropriate alternative.

Looks good! No objections.

On the section for "If you want to contribute to the project:" what about mentioning the one-step dev environment by either adding a link to the README or adding the command to the list of shell commands given?

# Step 1: clone your fork
git clone https://github.com/<YOUR GIT USERNAME>/magento-lts
cd magento-lts
git remote add upstream https://github.com/OpenMage/magento-lts
git pull upstream 1.9.4.x

# Step 2: start the dev environment
dev/openmage/install.sh

# Step 3: hack some improvements and create a Pull Request
git checkout -b your-branch
git add -A
git commit
git push origin your-branch

@colinmollenhour Absolutely, but I'd like to leave that up to you. I would prefer the link to a README, this one you can manage yourself without needing PRs here.
