+Linux Snap
+---
+A Linux Solana [Snap](https://snapcraft.io/) is available, which can be used to
+easily get Solana running on supported Linux systems without building anything
+from source.  The `edge` Snap channel is updated daily with the latest
+development from the `master` branch.  To install:
+```bash
+$ sudo snap install solana --edge --devmode
+```
+(`--devmode` flag is required only for `solana.fullnode-cuda`)
+
+Once installed the usual Solana programs will be available as `solona.*` instead
+of `solana-*`.  For example, `solana.fullnode` instead of `solana-fullnode`.
