+
+# Manual build
+To build this project on Linux, simply follow the instructions below. Windows will only work if you use something like WSL2 or MINGW64.
+
+1. cd to the project folder (for this i'll just use /usr/vid-encode)
+
+`cd '/usr/vid-encode/Video Encode 2'`
+
+2. use g++ to build main.cpp
+
+`g++ main.cpp lodepng.cpp -o video_encode $(pkg-config --cflags --libs opencv4) -lavcodec -lavformat -lavutil -lswscale`
+
+
+3. use `./video_encode encode /path/to/your/file` to encode files and `./video_encode decode /path/to/encoded/video` to decode.
+
+# Use included auto builder
+1. Download the install.sh from the repo.
+
+2. Run it. It will automatically install to ~/Desktop/vid-encode and you can run the program by going to ~/Desktop/vid-encode/Video Encode 2 and running ./video_encode.
+
+## Requirements
+You will need FFMPEG and Opencv2 to actually use the program. All requirements for building are included.
