 # nim-libnx
-Libnx ported to the Nim programming language. You will need a nim compiler with Nintendo switch support which can be found [here](https://github.com/jyapayne/Nim/tree/nintendo_switch_support) until the PR is accepted.
+Libnx ported to the Nim programming language. You will need a Nim compiler with Nintendo switch support which can be found in the latest devel branch of the Nim compiler.
 
-You also must have DevkitPro and switch (libnx) libraries for [Mac and Linux](https://github.com/devkitPro/pacman/releases) or [Windows](https://github.com/devkitPro/installer/releases) installed. The DEVKITPRO environment variable must also exist and point to a directory with the following structure:
+You also must have DevkitPro and switch (libnx) libraries for [Mac and Linux](https://github.com/devkitPro/pacman/releases) or [Windows](https://github.com/devkitPro/installer/releases) installed.
+
+From dkp-pacman, the switch libraries can be installed with:
+
+```
+dkp-pacman -Syu
+dkp-pacman -S switch-dev
+## When it asks for installation options, choose the default which will install everything
+```
+
+The DEVKITPRO environment variable must also exist and point to a directory with the following structure:
 
-- `DEVKITPRO/portlibs/switch/lib`
 - `DEVKITPRO/libnx/lib`
-- `DEVKITPRO/portlibs/switch/include`
 - `DEVKITPRO/libnx/include`
 
+OR you must specify a valid libnx path and/or devkitpro path to the `switch_build` utility:
 
-##Install
+```bash
+switch_build --libnxPath:"C:\devkitPro\libnx" --author:"Joey" --version:"1.0.0" .\examples\accounts\account_ex.nim
+# OR
+switch_build --devkitProPath:"C:\devkitPro" --author:"Joey" --version:"1.0.0" .\examples\accounts\account_ex.nim
+```
+
+## Install
 
 Simply run
 
 ```bash
 # Because of a bug in nimble right now, you must install this first!
-nimble install "https://github.com/jyapayne/nimgenEx#head"
+nimble install nimgen@#head
 nimble install
 ```
