+# This changes the js-sdk into 'release mode', that is:
+# * The entry point for the library is the babel-compiled lib/index.js rather than src/index.ts
+# * There's a 'typings' entry referencing the types output by tsc
+# We do this so we can test that each PR still builds / type checks correctly when built
+# against the released js-sdk, because if you do things like `import { User } from 'matrix-js-sdk';`
+# rather than `import { User } from 'matrix-js-sdk/src/models/user';` it will work fine with the
+# js-sdk in development mode but then break at release time.
+# We can't use the last release of the js-sdk though: it might not be up to date enough.
