+# li18nt UI text style checker
+
+The purpose of this tool is to provide style "lint" checking for the en.json
+file, which is used as the starting point for i18n in the user interface. The
+definitive guidelines can be found in the main
+[style guide](https://docs.alfresco.com/sites/docs.alfresco.com/files/public/docs_team/u2/Alfresco-Writing-Guide.pdf) document. This tool implements the guidelines as a set of rules that can be
+checked automatically for common errors (the [style rules](../UIStyleRules.md) file
+contains a full description of the rules currently in use).
+
+## Installing and using the VSCode extension
+
+The VS Code extension shows the style warnings as underlined sections in the text
+with corresponding notes in the Problems window, a lot like standard programming
+language errors.
+
+The extension is not available in the VS Code marketplace but you can install it
+locally by copying it to the extensions folder. This can be found at the path
+
+`$HOME/.vscode/extensions`
+
+...on MacOSX and at
+
+`%USERPROFILE%\.vscode\extensions`
+
+...on Windows. Copy the `client` folder (from `alfresco-ng2-components/tools/i18n/li18nt/`)
+to the extensions folder and rename it to `li18nt`. If there is no `node_modules`
+folder in the new `li18nt` folder then you should also `cd` into this folder and
+run `npm install`. When you restart VS Code, you should find `li18nt` listed among
+the installed extensions in the extensions panel.
+
+When active, the extension will only check the text of files named `en.json`.
+Double-click an item from the Problems window in VS Code to highlight the section
+of text where the issue occurs. You can find out more about why the error has
+occurred and what to do about it in the [style rules](../UIStyleRules.md) file.
+For the full description and explanation of all style guidelines, see the main
+[style guide](https://docs.alfresco.com/sites/docs.alfresco.com/files/public/docs_team/u2/Alfresco-Writing-Guide.pdf).
