+# QNAP nzbget packages
+
+We support QNAP via native qpkg packages, built with QNAP toolchains (only x86/x86_64/arm_64 QNAP architectures) and buildroot qpkg, repacked from linux installer (all QNAP architectures)
+
+## Installing
+
+Prerequsites: Enable installation of applications without digital signature (`AppCenter` - `Settings` - `Allow installation of applications without a valid digital signature`)
+
+To install nzbget for QNAP download qpkg for your architecture, then from QNAP AppCenter select `Install Manually` - browse for downloaded qpkg and press `Install`
+For digital signature warning select `I understand the risks and want to install this application` and press `Install`.
+After installation - Press `Open` in AppCenter or click NZBGet icon on desktop. Default login/password for WebUI
+```
+Login: nzbget
+Password: tegbzn6789
+```
+
+## Configuring
+
+Change `PATHS` - `MainDir` to point to shared folder location, for example
+```
+/share/CACHEDEV1_DATA/Public/nzbget
+```
+By default, nzbget will download all files to package directory, inaccessible from shares.
+
+## Extensions
+
+QNAP packaged with python2. To support python3 extensions, need to install Python3 package from QNAP Store, and add to `EXTENSION SCRIPTS` - `ShellOverride` path to python3 executable like this:
+```
+.py=/share/CACHEDEV1_DATA/.qpkg/Python3/python3/bin/python3;
+```
+
+## Known issues:
+
+- Some extensions (VideoSort) does not work correctly with above setting until ntsbget is fully restarted. From AppCenter select NZBGet - from drop-down menu select stop and then start.

+# About
+
+"build-nzbget.sh" is a bash script which is used to build nzbget QNAP packages.
+
+
+# Prerequisites
+
+- linux x86_64 host (Ubuntu 22.04 LTS for example)
+
+We support building nzbget for QNAP for x86 / x86_64 / arm_64 architectures only, because other platforms toolchains is too old (nzbget need gcc 4.9+ for building).
+
+- download x86/x86_64 toolchains from http://download.qnap.com/dev/Toolchain/QNAP_cross_toolchains_64.20160606.tar
+- download arm_64 toolchain from http://download.qnap.com/dev/Toolchain/aarch64-QNAP-linux-gnu.tgz
+- extract toolchains to $QNAP_ROOT/toolchain (default - /qnap/toolchain), needed directory structure for script:
+```
+/qnap/toolchain
+├── aarch64
+│   └── cross-tools
+├── i686
+│   ├── cross-tools
+│   └── fs
+└── x86_64
+    ├── cross-tools
+    └── fs
+```
+- install QDK from `https://github.com/qnap-dev/QDK`
+```
+git clone https://github.com/qnap-dev/QDK
+cd QDK
+sed 's|python|python3|' -i InstallToUbuntu.sh
+sudo ./InstallToUbuntu.sh install
+```
+
+## Building NZBGet
+
+From cloned repository run
+```
+bash qnap/build-nzbget.sh
+```
+
+## Output files
+
+- /qnap/nzbget/build/*.qpkg - one file per platform
