 This is a DSL created to define proposal transformations using templates. A transformation is defined by two templates, a template of what code snippets to search for **applicable to** and a template of how to transform those snippets **transform to**.
 
 Examples of definitions for proposals can be found in [dsl_files](./dsl_files/)
+
+## Running this project
+
+This project exposes an api in the file [transform/transfrom.ts](./src/transform/transform.ts), which is meant to be used as this library's entry point.
+
+To run this code as a standalone project, a file [index.ts](./index.ts) exists to facilitate running this project.
+
+This project is created using TypeScript, and it is recommended to use [Bun](https://bun.sh/) to compile and run it.
+
+### Building Langium required files
+
+Firstly, building langium is required, this is done by the following:
+
+```sh
+# cd into JSTQL
+cd JSTQL
+
+# Install dependencies
+npm i
+
+# Build langium generated files
+npm run langium:generate
+
+# Build final JS source
+npm run build
+```
+
+### Running a transformation
+
+Now we are ready to run this project with the pipeline on a test JS file:
+
+```sh
+# cd into top level
+cd ..
+
+# Install dependencies
+bun i
+
+# Run an example transformation
+bun run index.ts dsl_files/pipeline.jstql test_files/test.js
+```
+
+### Arguments of index.ts
+
+Arguments
+
+-   First positional is path to JSTQL
+-   Second positional is path to JS file to transform
+-   -o is optional output path, if not given path is **./out.js**
