-1. Use Linux host
+You are supposed to be running **Ubuntu 22.04 LTS** with a home directory at `/home/vboxuser` (Update paths in the commands below and `ogspkg/games/memory/Makefile` if your home directory is different)
+
+1. Install necessary dependencies:
+	```
+	apt install libtinfo5 gawk
+	```
+1. Place this Memory game repository clone to `~/research-portable-memory`
 1. Download the last supported [SDK 17.01.7](https://downloads.openwrt.org/releases/17.01.7/targets/ar71xx/generic/lede-sdk-17.01.7-ar71xx-generic_gcc-5.4.0_musl-1.1.16.Linux-x86_64.tar.xz)
 1. Unpack it to `~/openwrt-sdk`:
 	```
 	tar -xf lede-sdk-17.01.7-ar71xx-generic_gcc-5.4.0_musl-1.1.16.Linux-x86_64.tar.xz
 	mv lede-sdk-17.01.7-ar71xx-generic_gcc-5.4.0_musl-1.1.16.Linux-x86_64 ~/openwrt-sdk
 	```
-1. 
+1. ?? Set PATH https://openwrt.org/docs/guide-developer/helloworld/chapter1#adjusting_the_path_variable
+1. Create `feeds.conf` pointing to `ogspkg`:
+	```
+	echo 'src-link ogspkg /home/vboxuser/research-portable-memory/platform-OpenWrt/ogspkg' > ~/openwrt-sdk/feeds.conf
+	```
+1. Update feeds:
+	```
+	~/openwrt-sdk/scripts/feeds update ogspkg
+	~/openwrt-sdk/scripts/feeds install -a -p ogspkg
+	```
+1. Run `make menuconfig` from `openwrt-sdk`
+1. Make sure `Games -> ogs-memory` is selected as Module <M>, `Save` if necessary
+1. Build the package:
+	```
+	cd ~/openwrt-sdk
+	make package/ogs-memory/compile
+	```
+1. Transfer built `~/openwrt-sdk/bin/packages/ogspkg/ogs-memory*ipk` to `/tmp` on the device with OpenWrt
+1. Install package to device's RAM:
+	```
+	opkg install /tmp/ogs-memory*ipk -d ram
+	```
+1. Run `ogs-memory`:
+    ```
+    LD_LIBRARY_PATH=/tmp/usr/lib /tmp/usr/bin/ogs-memory
+    ```
