+# flow-texpack
+
+`flow-texpack` is a program that will allow you to generate texture atlas from
+input images (BMP, HDR, JPG, PNG, TGA, TIFF, WEBP). The application generates
+both texture atlas and descriptions file that can be read by a game.
+
+## Installation
+
+Install `Rust` from your package manager or by downloading from here:
+[https://rust-lang.org/](https://rust-lang.org/).
+
+## Build
+
+Build using release mode and install locally (on GNU/Linux this is `~/.cargo/bin`):
+
+```sh
+cargo install --locked --path .
+```
+
+## Example usage
+
+Show available options:
+
+```sh
+flow-texpack -h
+flow-texpack --help
+```
+
+Examples:
+
+```sh
+flow-texpack -i data/characters data/tiles -o out/atlas -m -t -u -r -p 2 -v
+flow-texpack -i data/characters data/tiles -o out/atlas -m -t -u -r -p 2 -v --load-filter png tga
+flow-texpack -i data -e data/tiles -o out/atlas -m -t -u -r --atlas-size pot2048 --rect-heuristic area-fit -v
+flow-texpack --input-file input.txt --exlude-file exclude.txt -o out/atlas -v
+flow-texpack -i data/characters data/tiles -o out/atlas -m -t -u -r --adjust-size -v
+flow-texpack -i data/characters data/tiles -o out/atlas -m -t -u -r --adjust-fit -v
