+# `generic_flags` API
+
+Programmers can use the following Lua functions to add custom flags,
+get a list of all flags, and set and get the flag of flag pole nodes.
+
+## Functions
+
+### `generic_flags.add_flag(name)`
+
+Add a new flag to the game. `name` is the flag identifier.
+There *must* exist a texture with the name `flag_<name>.png`.
+The texture *should* have an aspect ratio of 1.3.
+The recommended size is 78×60, but other sizes are OK
+as long the aspect ratio is respected.
+
+The flag name *must not* already exist. This will be checked.
+
+On success, the flag will be appended to the list of flags at the end.
+
+If a flag with the given name already exists, no flag will be
+added.
+
+Returns `true` on success and `false` on failure.
+
+### `generic_flags.get_flags()`
+
+Returns a list of all available flag identifiers. The flags
+are sorted by selection order.
+
+### `generic_flags.set_flag_at(pos, flag_name)`
+
+Sets the flag at an upper mast node at position `pos` to the flag `flag_name`.
+The node at `pos` *must* be `generic_flags:upper_mast`.
+Returns `true` on success and `false` otherwise.
+
+### `generic_flags.get_flag_at(pos)`
+
+Returns the currently used flag at the upper mast node at position `pos`.
+The node at `pos` *must* be `generic_flags:upper_mast`.
+Returns a string on success and `nil` otherwise.
+
+### `generic_flags.get_wind(pos)`
+
+Returns the current wind strength at pos. The wind strength determines how
+fast a flag at pos would be waving at the time this function was called.
+
+This function will be called from time to time by the mod to update
+the flag waving speed of flags. It is called for every flag once about
+every 115 seconds (plusminus 10 seconds).
+
+This function is predefined in this mod by pseudorandomly changing the wind
+strength over time using a Perlin noise. By default, the wind strength is
+only controlled by the current time; the position is ignored.
+
+This function can be overwritten by mods to define your own wind algorithm.
+You can do whatever in this function, you only need to return a number in
+the end. The number should be roughly in the range between 0 and 50.
+
+This is how the wind strength affects the flag waving speed:
+
+* wind < 10: slow
+* 10 < wind < 20: medium
+* 20 < wind < 40: fast
+* wind > 40: very fast
