# 4. Activate Secret Toggle

Lando has a secret contributor mode that you need to engage to contrib. Complete the sections below to make that happen.

# Fork and install Lando from source

• If you are not a Lando committer with write access to the official repo start by forking Lando.
• Follow the install from source instructions using either the official repo or the fork you made in Step 1.

# Engage Contrib Mode

• Verify you've installed from source correctly

# Ensure you have the correct version of node installed
node -v | grep v10. || echo "Wrong node version"

# Ensure you have yarn install
yarn -v || echo "Yarn not installed"

# Ensure you can run lando.dev
lando.dev

• Activate the secret toggle

# Activate the secret toggle
lando.dev --secret-toggle

# Verify the toggle is on
lando.dev contrib:list || echo "\n\nSecret toggle not on"
