+## Tutorial
+
+This action allows you to replace variables in a text file. The variables are defined in a map and can be used in the
+text file with the following syntax: `{_ variable _}`. Spaces are allowed around the variable name.
+
+### Example
+
+Here's an example of how to use:
+
+```typescript
+import { processFiles } from 'library';
+
+const variables = new Map<string, string>();
+variables.set('EXAMPLE', 'World');
+variables.set('what', 'Hello');
+
+processFiles({
+  files: ['readme.prp.md'],
+  variables: variables,
+  encodings: 'utf8',
+  extension: '.prp.md'
+});
+```
+
+### Greetings
+
+{_ what _}, {_ EXAMPLE _}! {_what _} {_ EXAMPLE_}{_what_}
+
+### Complex Variables
+
+This section includes variables with more complex names to test the robustness of the regular expression in
+the `replaceVariables` function.
+
+{_ variable with spaces _}
+{_ variable_with_underscores _}
+{_ variable-with-dashes _}
+{_ variable.with.dots _}
