+# Sandpass
+
+Sandpass is a web-based password manager based on the Keepass database format
+that runs on [Sandstorm](https://sandstorm.io/). Sandpass is still under
+development, so expect some rough edges.
+
+## Installing
+
+Once Sandpass is released on the Sandstorm App Market, it will be as simple as
+one click to Demo and Install on Oasis.
+
+## Building
+
+Prerequisite: [Go 1.6](https://golang.org/dl/)
+
+```
+go get zombiezen.com/go/sandpass
+cd $GOPATH/zombiezen.com/go/sandpass
+```
+
+Running as a normal HTTP server:
+
+```
+sandpass -db=foo.db -listen=localhost:8080 -permissions=false
+```
+
+Running as a Sandstorm app (requires [vagrant-spk](https://docs.sandstorm.io/en/latest/vagrant-spk/installation/)):
+
+```
+vagrant-spk dev
+```
