+## Build
+See https://handbook.gnome.org/development/building.html
+
+## Coding Style
+Basic code formatting can be done by running the formatting script `build-aux/run-uncrustify.sh`.
+It is also run via a merge request CI pipeline to catch any oversights.
+
+Nautilus has a lot of legacy code that would not be written the same way today.
+Some general guidelines for the current code style:
+
+* Use [automatic cleanups](https://docs.gtk.org/glib/auto-cleanup.html) when possible
+* Declare variables where they are needed and assign them directly if possible
+* Explicitly compare pointers with `NULL` (`if (variable != NULL)` instead of `if (variable)`)
+* Place empty lines between between blocks of declarations, expressions and return statements
+* Keep line lengths below 100, put a line break after `=` or between function parameters if needed
+* Prefer early returns over nested if cases
+
+You can look at newer changes to see these guidelines in practice.
+Example code block:
+
+    g_autoptr (Type) autocleanup_variable = inline_initialization ();
+
+    if (variable == NULL)
+    {
+        return early;
+    }
+
+    g_autofree char *define_variables_where_used =
+        use_line_break_after_assignment_if_line_would_get_too_long ();
+
+    function_call_separated_by_empty_line ();
+    expressions += function_calls (are_grouped);
+
+    return statement_separated_by_another_empty_line;

+## Unit Tests
+Enable building unit tests from the `test/` directory by setting the respective
+meson option (`-Dtests=all`).
+You can then run them, e.g. with `meson test -C build`.
+The tests are also run via a merge request CI pipeline to avoid regressions.
+
+## Build With Address Sanitizer
+* Install `libasan` in the build environment
+* Reconfigure meson to use sanitizer, e.g. with:
+
+    `meson setup --reconfigure --prefix=$PREFIX build -Db_sanitize=address`
+* The sanitizer will inform you about leaked data on exiting.
+  This is most useful in combination with unittests
