merely a port of the official plugins.

+# LV2 port of Airwindows audio plugins.
+
+This is only a (for now incomplete/experimental) port of the audio plugins
+created by Chris Johnson/Airwindows. All the DSP work is by him, all this repo
+adds is a bit of wrapper code and a option to build the plugins as LV2 plugins.
+
+For information on the plugins, see the [Airwindows
+website](https://www.airwindows.com/category/vst/).
+
+See the `plugins/LV2/` directory for build [build
+instructions](plugins/LV2/README.md) and more info on this port.

+# Airwindows open-source LV2 plugins for Linux
+
+This repository contains a CMake project that builds Airwindows plugins for
+Linux. Thanks to the Patreon supporters, Chris now publishes some of his plugins
+under the MIT license on his GitHub, thus making this possible. Please, consider
+supporting him. More info:
+
+1. <https://patreon.com/airwindows>
+2. <https://github.com/airwindows/airwindows>
+3. <http://airwindows.com>
+
+This port to the LV2 plugin format is done by Harald Eilertsen, based on the CMake
+buildsystem [Eugene Cherny](https://github.com/ech2) made for the LinuxVST port
+of the plugins.
+
+1. <https://code.volse.net/audio/plugins/airwindows-lv2-port.git>
+
+## Building
+
+Install CMake from your package manager:
+
+- Debian / Ubuntu: `apt install cmake`
+- Fedora / CentOS: `dnf install cmake`
+- Arch / Manjaro: `pacman -S cmake`
+
+Then make a directory where you want the project built, `build` is a good candidate.
+Then:
+
+```
+% cd build
+% cmake -DCMAKE_BUILD_TYPE=Release ..
+% make
+```
+
+You should now have a `lv2` subdirectory with another level of subdirectories,
+one for each plugin, copy these to your LV2 folder to install:
+
+```
+% mkdir ~/.lv2
+% cp -r ./lv2/* ~/.lv2/
+```
+
+To build a debug build, set `CMAKE_BUILD_TYPE=Debug` instead.
+
+## Adding new plugins
+
+1. Create a new directory `PluginName` in the `src` dir.
+2. Copy the plugin’s `.cpp` and `.h` files to it.
+3. Add line `add_airwindows_plugin(PluginName)` to the root `CMakeLists.txt`.
+   This will create a new target `PluginName` with all the sources copied, as
