-## Release
-### Build
-At first, you have to build.
-
-```bash
-$ make build
-```
-
-This command only generate javascript codes for Electron, so if you want to create release package, please read following document.
-
-### Binary
-I use `electron-builder` to create package, but it is hidden by Makefile. So you can use make command.
-
-```bash
-# for linux
-$ make linux VERSION=2.8.0
-
-# for 64 bit Windows
-$ make wi64 VERSION=2.8.0
-```
-
-You have to use macOS to build packages for macOS.
-And you have to install certificates for Mac Application.
-
-- Mac App Distribution: `Developer ID Application: Akira Fukushima (DR9TBDD8DFM)`
-- Mac App Installer Distribution: `Developer ID Application: Akira Fukushima (DR9TBDD8DFM)`
-
-Then use make command.
-
-```bash
-# for mac
-$ make mac VERSION=2.8.0
-```
-This command automatically loads the Developer ID Application certificate from your keychain.
-If you want to specify a certificate, please set `CSC_NAME` before this command.
-
-
-```bash
-$ export CSC_NAME="Akira Fukushima (DR9TBDD8DFM)"
-$ make mac VERSION=2.8.0
-```
-
-### AppStore
-
-Please prepare certificates on your Apple developer console. The following keys are required:
-
-- Mac App Distribution: `3rd Party Mac Developer Application: Akira Fukushima (DR9TBDD8DFM)`
-- Mac Installer Distribution: `3rd Party Mac Developer Installer: Akira Fukushima (DR9TBDD8DFM)`
-
-and register your KeyChain.
-
-Then, create a Mac App ID like `org.whalebird.desktop`.
-
-```bash
-$ yarn run build:mas
-
-# This command automatically loads the certificates from you keychain.
-$ ./appStore.sh
-```
-
-After that, the `.pkg` file is created under `./packages`.
-
-Please upload the `.pkg` to App Store using Application Loader in Xcode.
-
-### Snapcraft
-
-First, please prepare snapcraft command.
-
-```bash
-$ brew install snapcraft
-```
-or
-
-```bash
-$ snap install snapcraft --classic
-```
-
-Build command for linux generates a snap file.
-
-```bash
-$ make linux VERSION=2.8.0
-```
-
-And upload.
-
-```bash
-$ snapcraft push build/Whalebird-2.8.0-linux-amd64.snap  --release beta
-```
