 # TinyLoad
-Packer for PE files
+
+simple PE packer for Windows. compresses and optionally XOR-encrypts executables into a self-extracting stub.
+
+## how it works
+
+TinyLoad appends your compressed payload to a copy of itself. when the packed exe runs it extracts the original to a temp folder, runs it, waits for it to finish, then deletes it.
+
+everything is in one .cpp file, no dependencies.
+
+## download
+
+grab a precompiled binary from [releases](https://github.com/user/tinyload/releases) or build it yourself.
+
+## building from source
+
+you need MinGW (g++) installed. just run:
+
+```
+g++ -o TinyLoad.exe TinyLoad.cpp -static -O2 -s
+```
+
+or use the included `build.bat`.
+
+## usage
+
+```
+TinyLoad.exe --i <input> [--o <output>] [--xor] [--c]
+```
+
+| flag | description |
+|------|-------------|
+| `--i <file>` | input exe to pack |
+| `--o <file>` | output path (default: `input_packed.exe`) |
+| `--xor` | rolling XOR encryption on the payload |
+| `--c` | LZ77 compression |
+
+### examples
+
+```
+TinyLoad.exe --i myapp.exe --c
+TinyLoad.exe --i myapp.exe --o packed.exe --xor --c
+TinyLoad.exe --i myapp.exe --xor
+```
+
+you need at least one of `--xor` or `--c`.
+
+## compression
+
+custom LZ77 with hash-chain matching, 64KB sliding window, and lazy evaluation. typically gets decent ratios on PE files since they have a lot of repeated structure. compression runs on the raw input first, then XOR is applied on top so patterns in the compressed stream are also hidden.
