+# Sampler Chugin
+
+## Patching Chuck
+
+In the root of the chugins directory, there's a git diff file `vst_patch.patch`. Open a command window to the root and apply the patch: `git apply vst_patch.patch`. This will change a file in `chugins/chuck/include`. Don't commit these changes to the repo. Be prepared to undo them once the patch is no longer necessary.
+
+## Installation on Windows
+
+Update submodules:
+`git submodule update --init --recursive`
+
+Create an extra folder for your chugins, `%USERPROFILE%/Documents/ChucK/chugins/`. Create a system environment variable `CHUCK_CHUGIN_PATH` equal to this path.
+
+In `chugins/Sampler`, open a Windows command window:
+
+```
+mkdir build
+cd build
+cmake ..
+```
+
+Then open `chugins/Sampler/build/Sampler.sln` and build in 64-bit Release mode. You should see a new Sampler.chug file in the chugins folder you created earlier.
+
+Build 64-bit chuck.exe from [source](https://github.com/ccrma/chuck/tree/main/src/visual-studio). If you want to use [miniAudicle](https://github.com/ccrma/miniAudicle), then miniAudicle must also be 64-bit. Check that your chuck is 64-bit with `chuck --version`.
+
+Run any of the test scripts: `chuck.exe "tests/sampler_test.ck"`.
+
+## License
+
+The Sampler chugin uses [Sampler](https://github.com/DBraun/Sampler), which uses JUCE, so you must follow all of the licenses.
