+## Using Custom Block Tools
+
+You can now add custom block tools by serving a js file named "custom-editorjs-tools.js" in the static folder, this can contain any custom block tool, let's imagine it contains a *SimpleImage* block tool. You can now use this block by setting something like this in the configuration. **Warning: The class content should not ever depend on user input or any nontrusted input, as it could lead to xss**
