 Flag Specifier Format
 ---------------------
-Flags using the standardized flag specifier format can be specified in either of
-two ways, by string or table.
 
-The string format is a comma-delimited set of flag names; whitespace and
+Refer to `lua_api.md`.
-unrecognized flag fields are ignored. Specifying a flag in the string sets the
-flag, and specifying a flag prefixed by the string `"no"` explicitly
-clears the flag from whatever the default may be.
-
-In addition to the standard string flag format, the schematic flags field can
-also be a table of flag names to boolean values representing whether or not the
-flag is set. Additionally, if a field with the flag name prefixed with `"no"`
-is present, mapped to a boolean of any value, the specified flag is unset.
-
-E.g. A flag field of value
-
-```lua
-{place_center_x = true, place_center_y=false, place_center_z=true}

-is equivalent to
-

-HUD element types
------------------
-The position field is used for all element types.
-
-To account for differing resolutions, the position coordinates are the percentage
-of the screen, ranging in value from `0` to `1`.
-
-The name field is not yet used, but should contain a description of what the
-HUD element represents. The direction field is the direction in which something
-is drawn.
-
-`0` draws from left to right, `1` draws from right to left, `2` draws from
-top to bottom, and `3` draws from bottom to top.
-
-The `alignment` field specifies how the item will be aligned. It ranges from `-1` to `1`,
-with `0` being the center, `-1` is moved to the left/up, and `1` is to the right/down.
-Fractional values can be used.
-
-The `offset` field specifies a pixel offset from the position. Contrary to position,
-the offset is not scaled to screen size. This allows for some precisely-positioned
-items in the HUD.
-
-**Note**: `offset` _will_ adapt to screen DPI as well as user defined scaling factor!
-
-Below are the specific uses for fields in each type; fields not listed for that type are ignored.
-
-**Note**: Future revisions to the HUD API may be incompatible; the HUD API is still
-in the experimental stages.
-
-### `image`
-Displays an image on the HUD.
-
-* `scale`: The scale of the image, with 1 being the original texture size.
-  Only the X coordinate scale is used (positive values).
-  Negative values represent that percentage of the screen it
-  should take; e.g. `x=-100` means 100% (width).
-* `text`: The name of the texture that is displayed.
-* `alignment`: The alignment of the image.
-* `offset`: offset in pixels from position.
-
-### `text`
-Displays text on the HUD.
-
-* `scale`: Defines the bounding rectangle of the text.
-  A value such as `{x=100, y=100}` should work.
-* `text`: The text to be displayed in the HUD element.
-* `number`: An integer containing the RGB value of the color used to draw the text.
-  Specify `0xFFFFFF` for white text, `0xFF0000` for red, and so on.
-* `alignment`: The alignment of the text.
-* `offset`: offset in pixels from position.
-
-### `statbar`
-Displays a horizontal bar made up of half-images.
-
-* `text`: The name of the texture that is used.
-* `number`: The number of half-textures that are displayed.
-  If odd, will end with a vertically center-split texture.
-* `direction`
-* `offset`: offset in pixels from position.
-* `size`: If used, will force full-image size to this value (override texture pack image size)
-
-### `inventory`
-* `text`: The name of the inventory list to be displayed.
-* `number`: Number of items in the inventory to be displayed.
-* `item`: Position of item that is selected.
-* `direction`
-* `offset`: offset in pixels from position.
-
-### `waypoint`
-
-Displays distance to selected world position.
-
-* `name`: The name of the waypoint.
-* `text`: Distance suffix. Can be blank.
-* `precision`: Waypoint precision, integer >= 0. Defaults to 10.
-  If set to 0, distance is not shown. Shown value is `floor(distance*precision)/precision`.
-  When the precision is an integer multiple of 10, there will be `log_10(precision)` digits after the decimal point.
-  `precision = 1000`, for example, will show 3 decimal places (eg: `0.999`).
-  `precision = 2` will show multiples of `0.5`; precision = 5 will show multiples of `0.2` and so on:
-  `precision = n` will show multiples of `1/n`
-* `number:` An integer containing the RGB value of the color used to draw the
-  text.
-* `world_pos`: World position of the waypoint.
-* `offset`: offset in pixels from position.
-* `alignment`: The alignment of the waypoint.
-
-### `image_waypoint`
-
-Same as `image`, but does not accept a `position`; the position is instead determined by `world_pos`, the world position of the waypoint.
-
-* `scale`: The scale of the image, with 1 being the original texture size.
-  Only the X coordinate scale is used (positive values).
-  Negative values represent that percentage of the screen it
-  should take; e.g. `x=-100` means 100% (width).
-* `text`: The name of the texture that is displayed.
-* `alignment`: The alignment of the image.
-* `world_pos`: World position of the waypoint.
-* `offset`: offset in pixels from position.

+## Sign the Android APK from CI
+
+The [Github Actions Workflow](https://github.com/minetest/minetest/actions?query=workflow%3Aandroid+event%3Apush)
+automatically produces an APK for each architecture.
+Before installing them onto a device they however need to be signed.
+
+This requires an installation of the Android SDK and `adb`.
+```bash
+.../android-sdk/build-tools/30.0.3/apksigner sign --ks ~/.android/debug.keystore \
+	app-arm64-v8a-release-unsigned.apk
+# Enter 'android' (without quotes) when asked for a password
+```
+
+Note that the `debug.keystore` will not exist if you have never compiled an
+Android app on your system (probably).
+
+After that installing it will work:
+```bash
+adb install -r -d ./app-arm64-v8a-release-unsigned.apk
+```
+
+## How to get debug output from Minetest on Android
+
+In case debug.txt isn't enough (e.g. when debugging a crash), you can get debug
+output using logcat:
+
+`adb logcat -s 'Minetest:*' '*:F'`
+
+Note that you can do this even *after* the app has crashed,
+since Android keeps an internal buffer.
+
+A segmentation fault for example looks like this:
+
+```

+## Profiling Minetest on Linux
+
+We will be using a tool called "perf", which you can get by installing `perf` or `linux-perf` or `linux-tools-common`.
+
+For best results build Minetest and Irrlicht with debug symbols
+(`-DCMAKE_BUILD_TYPE=RelWithDebInfo` or `-DCMAKE_BUILD_TYPE=Debug`).
+
+Run the client (or server) like this and do whatever you wanted to test:
+```bash
+perf record -z --call-graph dwarf -- ./bin/minetest
+```
+
+This will leave a file called "perf.data".
+
+You can open this file with perf built-in tools but much more interesting
+is the visualization using a GUI tool: **[Hotspot](https://github.com/KDAB/hotspot)**.
+It will give you flamegraphs, per-thread, per-function views and much more.
