 ### Build
 
-Build all packages. You need to do this before working on any given package. Although these packages
-as independent, when run from within the monorepo, they are internally symlinked, to make development
-easier. You can change several packages and run the changes without publishing them first to NPM. When
-running `rebuild`, Lerna will figure out the dependency order of all the packages, and build them in
-this order.
+To build all packages:
+
+```bash
+yarn build
+```
+
+To build a specific package:
+
+```bash
+PKG=@0xproject/web3-wrapper yarn build
+```
+
+### Watch
+
+To re-build all packages on change:
+
+```bash
+yarn watch
+```
+
+To watch a specific package and all it's dependent packages:
+
+```bash
+PKG=[NPM_PACKAGE_NAME] yarn watch
+
+e.g

+```
+

+Clean all packages:

 #### Scripts
 
-**`yarn deps_versions`**: Since we use Lerna + Yarn workspaces, shared dependencies between packages in the monorepo get hoisted to a top-level `node_modules` directory. If two packages use different versions of the same dependency however, both get installed. To avoid having many versions of a dependency installed, we try to keep dependency versions the same across packages in the monorepo. This script will list any dependencies for which we have multiple versions installed. We can then go through them and try to consolidate to a single version where possible.

 **`yarn find_unused_deps`**: Sometimes we accidentally leave dependencies listed in `package.json` that are no longer being used. This script finds potential dependencies that might no longer be in use. Please verify that it is no longer in use before removing, the `depcheck` package we use under-the-hood doesn't handle some TS quirks perfectly.

 ### Build
 
-If this is your **first** time building this package, you must first build **all** packages within the monorepo. This is because packages that depend on other packages located inside this monorepo are symlinked when run from **within** the monorepo. This allows you to make changes across multiple packages without first publishing dependent packages to NPM. To build all packages, run the following from the monorepo root directory:
