+# Tutu
+
+Tutu is a comfortable experience for tooting. Designed to work on any device - desktop, phone and tablet.
+
+## Compatibility
+
+The code is built against those targets and Tutu must run on those platforms:
+
+| Firefox | Safari |  iOS  | Chrome | Edge |
+| ------- | ------ | ----- | ------ | ---- |
+|   98    |  15.4  | 15.4  |   84   |  87  |
+
+Tutu trys to push the Web technology to its limit. Some features might not be available on the platform does not meet the requirement.
+
+## Build & Depoly
+
+Tutu uses [bun](https://bun.sh) as the package manager. Run
+
+````sh
+bun install && bun dist
+````
+
+to build the distribution, saved at "dist" directory.
+
+Tutu must be loaded in a secure context - that means serving under localhost (`127.0.0.1` or `::1`) or HTTPS.
+
+Use `bun dev` to run the dev server. By default, the dev server is run on the domain <https://localhost.direct> and the port you defined. The cert is provided by localhost.direct, see <https://get.localhost.direct> for detail.
+
+You can also change the config to make it run on localhost - but localhost.direct can be visted from the other device on the same network (as you do a little DNS magic).
