 ### `npx squiggle-cli-experimental watch`
 
 Watches `.squiggleU` files in the current directory (and subdirectories) and rebuilds them when they are saved. Note that this will _not_ rebuild files when their dependencies are changed, just when they are changed directly.
+
+## Further instructions
+
+The above requires having node, npm and npx. To install the first two, see [here](https://nodejs.org/en/), to install npx, run:
+
+```
+npm install -g npx
+```
+
+Alternatively, you can run the following without the need for npx:
+
+```
+npm install squiggle-cli-experimental
+node node_modules/squiggle-cli-experimental/index.js compile
+```
+
+or you can add a script to your `package.json`, like:
+
+```
+ ...
+ scripts: {
+  "compile": "squiggle-cli-experimental compile"
+ }
+ ...
+```
+
+This can be run with `npm run compile`. `npm` knows how to reach into the node_modules directly, so it's not necessary to specify that.

+## 0.5.0
+
+- Performance improvements:
+  - Interpreter is now 5x-20x faster on code written in Squiggle
+  - SampleSet to PointSet conversions are 2x faster
+  - cdf function on SampleSets is 30x faster
+  - overall speedup is about 2x on average on real code written in Squiggle
+- 50% smaller bundle size for [@quri/squiggle-lang](https://www.npmjs.com/package/@quri/squiggle-lang); 20% smaller bundle size for [@quri/squiggle-components](https://www.npmjs.com/package/@quri/squiggle-components).
+
+### Breaking changes
+
+Some rarely used math functions got removed or moved to the `Math` namespace.
+
+For example, `cos(x)` is now `Math.cos(x)`, and `atanh(x)` doesn't exist.
+
+If your code is now failing with `<function> is not defined` for anything from [this list](https://mathjs.org/docs/reference/functions.html), try adding `Math.` prefix first, and then complain on [Github issues](https://github.com/quantified-uncertainty/squiggle/issues).
