 A simple self-hosted web server for creating and managing an avalanche forecast for a region, along with accepting public observations.
 
+## Design Considerations
+
+The following are goals that the project is striving to acheive (or has already achieved and needs to maintain) through careful decision making during the design process.
+
+1. Contains all the basics needed to run an avalanche forecasting service website.
+2. Reliable.
+  * Avalanche forecasts are an important public service.
+  * The only likely point of failure should be the host itself.
+  * Budget for on-call tech support is limited.
+2. Simple and easy to install and operate from an administrative perspective.
+  * Avalanche professionals or enthusiasts are for the most part not necessarily professional server administrators or software engineers.
+  * From this perspective, the server is a single self-contained binary that is dead easy to install and run on any computer/web server.
+  * A docker container is also provided.
+  * The database is using [sqlite](https://www.sqlite.org/index.html), which is embedded into the application (no need for a separate service), and the data consists of a single file.
+  * Database backup and restore functionality is built into the application.
+
