+## Build and Publish Snap Package workflow
+
+This workflow builds a `snap` package and uploads it to the [Snap Store](https://snapcraft.io/store).  It has a `workflow_dispatch` trigger so it can be triggered manually only, it is not hooked up to any other GH event.
+
+The store upload requires the `SNAPCRAFT_STORE_CREDENTIALS` variable to be set in [Github Secrets](https://github.com/decred/dcrdex/settings/secrets/actions).  
+See https://github.com/snapcore/action-publish for details.

+Build with `./pkg/pkg-debian.sh`. The deb archive will be located in **./build**.
+
+For development, you'll need to install the WebKit Development Libraries and the standard build toolchain:
+
+```bash
+sudo apt-get install libgtk-3-dev libwebkit2gtk-4.0-dev build-essential
+```
+For production, they are specified as DEPENDS in the control file and the package manager will install them.
+
+## Snap
+
+Snap is a package standard that can be installed on many Linux distributions from the Snap Store, and via software centers in e.g. Fedora, Ubuntu.
+
+### Preparing the build environment
+```bash
+# on Ubuntu 22.04 LTS:
+sudo apt-get install snap  
+# on Debian: 
+sudo apt-get install snapd
+
+sudo snap install --classic snapcraft
+sudo adduser $USER lxd
+newgrp lxd
+lxd init --auto
+sudo ufw disable # if ufw is installed on the host, this is neccessary for lxd to have network access
+
+```
+
+### Running the build
+
+ 1. Build the Debian package
+ 2. `./pkg/pkg-snap.sh`
+
+### Installing the .snap file locally
+
+`sudo snap install --dangerous build/bisonwallet*.snap`
+
+### Publishing the snap
+
+The snap can be uploaded to the Snap Store using `./pkg/publish-snap.sh`.  This requires [Snapcraft developer account credentials](https://snapcraft.io/docs/releasing-your-app).  After this is completed, the package can be installed on any system running `snap` by running `snap install bisonw`.  The app will be available on the [Snap Store](https://snapcraft.io/store/bisonw).
