+# Neural Capture
+
+A Neural Capture plug to make the process of cloning external soft/hardware a bit more comfortable 
+
+## Formats
+
+All plugins in this collection come in the following plug-in formats:
+
+* [LV2]
+* [VST2]
+* [VST3]
+* [CLAP]
+
+## Compiling
+
+Make sure you have installed the required build tools and libraries (see
+section "Prerequisites" below) and then clone this repository (including
+sub-modules) and simply run `make` in the project's root directory:
+
+```con
+git clone --recursive https://github.com:brummer10/neuralcapture
+cd neuralcapture
+make
+```
+
+## Installation
+
+To install all plugin formats to their appropriate system-wide location, run
+the following command (root priviledges may be required):
+
+```con
+make install
+```
+
+The makefiles support the usual `PREFIX` and `DESTDIR` variables to change the
+installation prefix and set an installation root directory (defaulty: empty).
+`PREFIX` defaults to `/usr/local`, but on macOS and Windows it is not used,
+since the system-wide installation directories for plugins are fixed.
+
+Use make's `-n` option to see where the plugins would be installed without
+actually installing them.
+
+You can also set the installation directory for each plugin format with a
+dedicated makefile variable.
+
+* LV2: `LV2_DIR` (`<prefix>/lib/lv2`)
+* VST2: `VST2_DIR` (`<prefix>/lib/vst`)
+* VST3: `VST3_DIR` (`<prefix>/lib/vst3`)
+* CLAP: `CLAP_DIR` (`<prefix>/lib/clap`)
+
+Example:
+
+```con
+make DESTDIR=/tmp/build-root PREFIX=/usr VST2_DIR=/usr/lib/lxvst install
+```
+
+To install the plugins only for your current user account, run:
+
+```con
+make install-user
+```
+
+Again, you can also set the installation directory for each plugin format with
+a dedicated makefile variable.
+
+* LV2: `USER_LV2_DIR` (`$HOME/.lv2`)
+* VST2: `USER_VST2_DIR` (`$HOME/.vst`)
+* VST3: `USER_VST3_DIR` (`$HOME/.vst3`)
+* CLAP: `USER_CLAP_DIR` (`$HOME/.clap`)
+
+*Note: The given default values for all of the above listed environment
+variables differ depending on the target OS.*
+
+
+## Prerequisites
+
+* The GCC C++ compiler, library and the usual associated software build tools
+  (GNU `make`, etc.).
+
+  Debian / Ubuntu users should install the `build-essential` package
+  to get these, Arch users the `base-devel` package group.
+
+* [pkgconf]
+
+The [LV2] and [VST2] (vestige) headers are included in the
+[DPF] framework, which is integrated as a Git sub-module. These need not be
+installed separately to build the software in the respective plug-in formats.
