Since the latest version of advmarkers doesn't work with 0.4 there is no reason
to keep depends.txt.

-A marker/waypoint mod for Minetest.
+A marker/waypoint mod for Minetest. Requires Minetest 5.0.0+, if you use Minetest 0.4 please try [this older version from June 2020](https://git.minetest.land/luk3yx/advmarkers/commit/25d7079069a53f2cece76ee2050bcdf690b4ea30).
 
 Unlike the [CSM], this mod is standalone, and conflicts with the marker mod.
 
 ## How to use
 
-`advmarkers` introduces the following chatcommands:
+This mod introduces the following chatcommands:
 
  - `/wp`, `/mrkr`: Opens a formspec allowing you to display or delete waypoints. If you give this command a parameter (`h`/`here`, `t`/`there` or co-ordinates), it will set your HUD position to those co-ordinates.
  - `/add_wp`, `/add_mrkr`: Adds markers. You can use `.add_mrkr x,y,z Marker name` to add markers. Adding a marker with (exactly) the same name as another will overwrite the original marker.
+ - `/clrwp`, `/clrmrkr`: Hides the currently displayed waypoint.
  - `/mrkr_export`: Exports your markers to an advmarkers string. Remember to not modify the text before copying it. You can use `/mrkr_export old` if you want an export string compatible with older versions of the advmarkers CSM (it should start with `M` instead of `J`). This old format does **not** work with this mod, so only use it if you know what you are doing!
- - `/mrkr_import`: Imports your markers from an advmarkers string (`.mrkr_import <advmarkers string>`). Any markers with the same name will not be overwritten, and if they do not have the same co-ordinates, `_` will be appended to the imported one.
+ - `/mrkr_import`: Imports your markers from an advmarkers string (`/mrkr_import <advmarkers string>`). Any markers with the same name will not be overwritten, and if they do not have the same co-ordinates, `_` will be appended to the imported one.
  - `/mrkrthere`: Alias for `/mrkr there`.

+If you die, a waypoint is automatically added at your death position, and will
 update the "there" position.
 
-### "Here" and "there" positions
+## "Here" and "there" positions
 
 Both /wp and /add_wp accept "here"/"h" and "there"/"t" in place of
 co-ordinates. Using "here" will set the waypoint to your current position, and
 "there" will set it to the most recent co-ordinates that appear in chat (or
 your last death position).
 
-## Chat channels integration
-
-advmarkers works with the `.coords` command from chat_channels ([GitHub],
-[GitLab]), even without chat channels installed. When someone does `.coords`,
-advmarkers temporarily stores this position, and you can set a temporary marker
-at the `.coords` position with `/mrkrthere`, or add a permanent marker with
-`/add_mrkr there Marker name`.
-
 ## SSCSM support
 
 With my [SSCSM] mod installed, advmarkers will register a server-sent CSM to
 reduce visible lag in the markers GUI.
