+# Updating DLLs
+The Windows DLLs are stored as releases in the [mxe](https://github.com/UltraStar-Deluxe/mxe) repository.
+
+If you need to update them:
+1. Open a PR in the [mxe](https://github.com/UltraStar-Deluxe/mxe) repository
+2. Open a PR in the USDX repository that updates the commit id in [dldlls.py](dldlls.py)
+3. Once everything works, merge the PR in the mxe repository
+4. Update the PR in the USDX repository to point to the commit id of the merge commit from step 3
+5. Merge the PR in the USDX repository and make a pre-release in the mxe repository. Pre-releases have `-rc1` added to the name of both the release and the zip asset!
+
+## Release updated DLLs
+When releasing a new version of USDX that uses new DLLs for the first time, edit the pre-release:
+* change the name (name it the same the USDX version you're about to release)
+* rename the zip asset
+* unmark it as pre-release
+* set as latest release
