+# Flame
+
+## Description
+Flame is self-hosted startpage for your server. It's inspired (heavily) by [SUI](https://github.com/jeroenpardon/sui)
+
+## Technology
+- Backend
+  - Node.js + Express
+  - Sequelize ORM + SQLite
+- Frontend
+  - React
+  - Redux
+  - TypeScript
+- Deployment
+  - Docker
+
+## Development
+```sh
+git clone https://github.com/pawelmalak/flame
+cd flame
+
+# run only once
+<TODO>
+
+# start backend and frontend development servers
+npm run dev
+```
+
+## Deployment with Docker
+```sh
+# build image
+docker build -t flame .
+
+# run container
+docker run \
+  -p 5005:5005 \
+  -v <host_dir>:/app/data \
+  flame
