 ## Benchmarks
 Benchmarks are located in `benchmark/YGBenchmark.c` and can be run with `buck run //benchmark:benchmark`. If you think your change has affected performance please run this before and after your change to validate that nothing has regressed. Benchmarks are run on every commit in CI.

+### JavaScript
+Installing through NPM
+```sh
+npm install yoga-layout
+```
+By default this will install the library and try to build for all platforms (node, browser asm, and standalone webpack). You may receive errors if you do not have the required platform development tools already installed. To preset the platform you'd like to build for you can set a .npmrc property first.
+```sh
+npm config set yoga-layout:platform standalone
+```
+This will now only run the standalone webpack build upon install.
+
+## Build Platforms

-# CHANGELOG
-
-The changelog for `YogaKit`.
-
-1.2.0 (**upcoming release**)
------
-
-### Breaking Changes
-
-- `applyLayout()` has now been changed to `applyLayout(preservingOrigin:)`.
-
-- Computed properties are no longer reflected in getter's of the affected properties.
-```swift
-// OLD
-view.yoga.margin = 10
-view.yoga.marginTop  // 10
-view.yoga.marginLeft // 10
-
-// NEW
-view.yoga.margin = 10
-view.yoga.marginTop // 0
-view.yoga.marginLeft // 0
-```
-
-### Enhancements
-
-- Pixel Rounding now uses `roundf()` instead of `round()`.
-
-- There is now a method that allows "bulk" updates to YGLayout.
-```objc
-[view configureLayoutWithBlock:^(YGLayout *layout) {
-  layout.isEnabled = YES;
-  layout.width = 50;
-  layout.height = 50;
-}];
-```
-
-```swift
-view.configureLayout { (layout) in
-  layout.isEnabled = true
-  layout.width = 50
-  layout.height = 50
-}
-```
-
-- Added new `isDirty` property, and make `markDirty` a little more performant.

 Using `MinWidth`, `MinHeight`, `MaxWidth`, and `MaxHeight` gives you increased control over the final size of items in a layout. By mixing these properties with `FlexGrow`, `FlexShrink`, and `AlignItems = Stretch`, you are able to have items with dynamic size within a range which you control.
 
-An example of when `Max` properties can be useful is if you are using `AlignItems = Stretch` but your know that your item won't look good after it increases past a certain point. In this case, your item will stretch to the size of its parent or until it is as big as specified in the `Max` property.

In this case, your item will stretch to the size of its parent or until it is as big as specified in the `Max` property.
 
 Same goes for the `Min` properties when using `FlexShrink`. For example, you may want children of a container to shrink to fit on one row, but if you specify a minimum width, they will break to the next line after a certain point (if you are using `FlexWrap = Wrap`).
