**Attention**: make sure the working directory contains the `src/assets/...` directory otherwise the application will crash (reporting a "FailedToLoadBitmap" error).
If you unzip the binaries package or build from sources this means that the root of the zip/sources is your working directory and you're executing `./zig-out/bin/jungle_tale` or `.\zig-out\bin\jungle_tale.exe`.

@ -50,13 +50,13 @@ For building you need:
- A recent (0.11.0-dev) Zig compiler.
- Allegro 5.2.8 development libraries.
You can use `allegro-dir` build option if your Allegro development libraries can't be natively found. In this file you can put the path to a directory that contains the Allegro `lib`, `bin` and `include` folders.
You can use `allegro.path` if your Allegro development libraries can't be natively found. In this file you can put the path to a directory that contains the Allegro `lib`, `bin` and `include` folders.
Build:
`zig build`
And run (after building):
`./zig-out/bin/jungle_tale`
`./zig-out/bin/tins2023`
Build & run automatically:
`zig build run`
