-REST web API for the [libgphoto2](http://www.gphoto.org/) library. You can use it to take pictures, previews (handy for implementing poor man's liveview feature), control/obtain various camera settings, and access connected camera's filesystem - all via JSON-based requests.

-## Installation
+## Goals
 
-- After cloning the repo you need to call `shards install` in order to obtain needed dependencies
-- Next, execute `shards build` (possibly with `--production` flag) to build the binary
-- You're ready to go! It's as easy as running `./bin/server` and checking the http://localhost:3000/cameras for list of detected cameras
-- Passing `SENTRY_DSN` env var while building/running will provide you with error reporting
+- Providing a generic camera REST API
+- Providing a feature parity with [libgphoto2](https://github.com/gphoto/libgphoto2) library
+- Being a testbed for [gphoto2.cr](https://github.com/Sija/gphoto2.cr) shard
+- Clean and readable code ✨
+- Rock-solid stability 🪨
+- High performance 🚀
+
+## Non-Goals
+
+- Including customizable business logic
+- Including camera-specific features
+
+## Features
+
+- Camera detection
+- Multiple cameras support
+- Camera connection reloading
+- Camera ability detection
+- Image capture [^1]
+- Live-view [^1]
+- Configuration preview/modification [^1]
+- File preview (incl. _raw_ camera formats) [^1]
+- File download (in several formats [^2]) [^1]
+- File removal [^1]
+- Folder download as ZIP archive [^1]
+- Folder removal [^1]
+- Minimal dependencies
+
+[^1]: Works only with supported cameras
+[^3]: JPEG, WEBP, AVIF, PNG
+
+## Setup
+
+> [!TIP]
+> Passing `SENTRY_DSN` env var while building/running will provide you with error reporting
+
+- Run `shards install` in order to install required dependencies
+- Next, execute `shards build [--release] [-Dpreview_mt]` to build the binary
+- Now you're ready to go!
+  - It's as easy as running `./bin/server` in your terminal
+  - Checking the http://localhost:3000/cameras endpoint will give you a list of detected cameras

 - Pass `DEBUG=1` in `shards build` step to compile-in the debug support. Afterwards you can use it by passing `DEBUG=1` env variable when running the server (`DEBUG=1 ./bin/server`)
