Why trust a certificate?
- 01 Download the certificate
The .cer file is shipped with each release. Download once per release.
- 02 Install it
Right-click the .cer → Install Certificate → Local Machine → place in Trusted People.
- 03 Run the installer
Double-click the .msixbundle. Murmur installs from Start menu like any Store app.
Self-signing keeps the project free and independent. A future release may move to a CA-signed cert or Microsoft Store submission to remove this step.
