+:::danger VSCode Telemetry and Data Exfiltration
+
+The official Microsoft builds of Visual Studio Code embed telemetry and send
+information to external servers.
+
+**[VSCodium](https://vscodium.com/) is a telemetry-free fork of VSCode.**
+
+When writing code that may process personally identifiable information (PII),
+the SheetJS team strongly encourages building VSCode from source or using IDEs
+that do not exfiltrate data.
+
+:::
+
+The type checker integrated in VSCodium and VSCode do not currently provide type
+hints when using the standalone build. Using the JSDoc `@type` directive coupled
+with type imports, VSCodium will recognize the types:
+
+![VSCodium types](pathname:///files/standalone-types.png)
+
+<ol start="1">
+<li><p>Download the types (<code parentName="pre">index.d.ts</code>) for
+   the desired version. The current version is available at <a href={"https://cdn.sheetjs.com/xlsx-" + current + "/package/types/index.d.ts"}>{"https://cdn.sheetjs.com/xlsx-" + current + "/package/types/index.d.ts"}</a></p></li>
+</ol>
+
+2) Rename the types file to `xlsx.d.ts`. It does not need to reside in the same
+folder as the standalone script.
+
+3) In the browser script referencing the global, prepend the following lines:
+
+```js title="Prepend this fragment in each source file referencing the XLSX global"
+/** @type {import("./xlsx")} */
+const XLSX = globalThis.XLSX;
+```
+
+4) If the `xlsx.d.ts` file is in a different folder, change the argument to the
+`import` method to reflect the relative path. For example, given the structure:
+
+```text title="Folder Structure"
+- /vendor
+  - /vendor/xlsx.ts
+- /src
+  - /src/app.js
+```
+
+`/src/app.js` must refer to the types as `../vendor/xlsx`:
+
+```js title="Preamble for /src/app.js when types are at /vendor/xlsx.d.ts"
+// highlight-next-line
+/** @type {import("../vendor/xlsx")} */
+const XLSX = globalThis.XLSX;
+```
+
+The `.d.ts` file extension must be omitted.
