-CloudCoinWallet-snap
+This is the Snap Packaging for Java-based [CloudCoin Wallet Desktop App](https://cloudcoinconsortium.com/use.html).
+
+Why to package the app with [Snapcraft](https://snapcraft.io/)?
+
+- **Snaps are easy to discover and install**
+  Millions of users can browse and install snaps graphically in the Snap Store or from the command-line.
+- **Snaps install and run the same across Linux**
+  They bundle the exact version of whatever is required, along with all of your app’s dependencies, be they Java modules or system libraries.
+- **Snaps automatically update to the latest version**
+  Four times a day, users’ systems will check for new versions and upgrade in the background.
+- **Upgrades are not disruptive**
+  Because upgrades are not in-place, users can keep your app open as it’s upgraded in the background.
+- **Upgrades are safe**
+  If your app fails to upgrade, users automatically roll back to the previous revision.
+
+## Install
+
+Go to the Release page to download the snap file that we built.
+
+Then, run the following command to install it.
+
+```bash
+sudo snap install cloudcoinwallet_2.1.18_amd64.snap --devmode
+```
+
+> NOTE:
+>
+> You need to finish the snapd installation on your Linux desktop first if not found snap command.
+
+## Rebuild (optional)
+
+To create a snap, you need to finish the installation of the [Snapcraft](https://snapcraft.io/), the snap-building tool.
+
+Since my Mint Linux desktop isn't supporting for the Snapcraft so I used Docker for Snapcraft.
+
+Build snapcraft image
+
+```bash
+$ docker build -t snapcraft:core18 .
+```
+
+Build snap app
+
+```bash
+$ docker run -v "$PWD":/build -w /build snapcraft:core18 snapcraft
+```
