+
+## Build
+
+Building this project requires the [stack] tool.
+
+[stack]: https://haskellstack.org/
+
+Within the project's directory, use
+
+* `stack setup` to setup the development environment and compiler.
+* `stack build` to compile the project.
+* or `stack build --fast --file-watch --pedantic` to automatically compile on file change.
+* `stack exec ldgallery-compiler-exe -- --help` to run the compiled program (and displaying its help text for instance).
