+This repo uses [rushjs] for mono-repo management.
 
 ### Setup
 
-This is a mono-repo and we use [fyn] to install and local linking packages when doing development. You can use `npm run`, but never use `npm install` in our repo else things will break. Below, `fun` is an alias for `npm run` that [fyn] provides.
+This is a mono-repo and we use [rushjs] to install and local linking packages when doing development. We use rushjs with pnpm. Read more [here]
 
-Install some CLI tools globally for convenience:
-
-```bash
-$ npm install -g xclap-cli @xarc/run-cli fyn
-```
 
 Fork and clone the repo at <https://github.com/electrode-io/electrode.git> and bootstrap all the packages.
 
 ```bash
 $ git clone https://github.com/<your-github-id>/electrode.git
 $ cd electrode

-$ fun bootstrap # run npm script bootstrap
+$ npm install -g @microsoft/rush # install rush
+$ rush install # installs package dependencies for all packages, based on the shrinkwrap file (pnpm-lock) that got created/updated using rush update.
+$ rush build # Run build command on all projects whose source files have changed since the last successful build

 ### **Useful** Notes
 
-- You should bootstrap the entire repo at the top dir at least once with `fun bootstrap`
-- After you make changes to any module under packages, if you want to test them in one of the samples, just run [fyn] in that sample and it will ensure all changed local packages are properly rebuilt and installed.

 #### Test with `@xarc/create-app`
 
 You can quickly use the `xarc-create-app` package to create an app for testing.
 
 ```bash
-$ cd samples
-$ node ../packages/xarc-create-app/src my-test-app
-$ cd my-test-app
-$ fyn

+$ cd samples && node ../packages/xarc-create-app/src my-test-app
