+### UV_TOOL_BIN_DIR
+
+On Windows `UV_TOOL_BIN_DIR` is set to the `TMP` dir. On GitHub hosted runners this is on the much
+faster `D:` drive. This path is also automatically added to the PATH.
+
+On all other platforms the tool binaries get installed to the
+[default location](https://docs.astral.sh/uv/concepts/tools/#the-bin-directory).
+
+If you want to change this behaviour (especially on self-hosted runners) you can use the
+`tool-bin-dir` input:
+
+```yaml
+- name: Install the latest version of uv with a custom tool bin dir
+  uses: astral-sh/setup-uv@v3
+  with:
+    tool-bin-dir: "/path/to/tool/bin"
+```
+
 ## How it works
 
 This action downloads uv from the uv repo's official
