 - `_makemenuconfig`: Invokes `make menuconfig` (ncurses-based default configuration menu) before compilation starts
 - `_makenconfig`: Invokes `make nconfig` (ncurses-based nicer configuration menu) before compilation starts
 - `_makexconfig`: Invokes `make xconfig` (X11-based GUI configuration menu) before compilation starts
-- `_use_current`: Will use the configuration of the running kernel, if the running kernel is compiled with `IKCONFIG_PROC`
+- `_reuse_current`: Will use the configuration of the running kernel, if the running kernel is compiled with `IKCONFIG_PROC`
+- `_reuse_file`: Will use the configuration file named `kconfig` contained in the `PKGBUILD` file's directory
+- `_update_kconfig_on_reuse`: Specifies whether the kernel configuration shall be updated when using any of the '_reuse_*' flags
 - `_copyfinalconfig`: Copies the final kernel configuration into the repository root as `kconfig-new` before compilation starts
 - `_localmodcfg`: Only compiles modules found in modprobed-db's database (which decreases compilation time and kernel size)
 - `_use_llvm_lto`: Compiles the kernel with LLVM instead of GCC. Should work, if not open an issue
-- `_subarch`: Specifies the sub architecture to compile for (see the [PKGBUILD file](https://git.staropensource.de/JeremyStarTM/aur-linux-clear/src/branch/develop/PKGBUILD) for a list of all subarches). Default is `41` (Generic x86-64), which is compatible with all amd64 processors. Must be a number

+- `_debug_kernel`: Force enables kernel debugging options when set to `y`, force disables debug options when set to `n` or relies on the kconfig when unset

+This repository (at least if you view it on [sos!git](https://git.staropensource.de/JeremyStarTM/aur-linux-clear))
+has two branches: `master` and `develop`. The `master` branch is the stable branch, where stable changes

 ## License
 This package does not yet have a license as the original repository (before [me](https://git.staropensource.de/JeremyStarTM) becoming it's maintainer) did not have one yet.
 I have contacted [metak](https://aur.archlinux.org/account/metak) (the previous maintainer) to negotiate a license.
