 # pythonista-jscore-runtime
 ## JSCore Runtime Framework - Execute JavaScript and WebAssembly in Pythonista 3 natively on iOS with JavaScriptCore.
-JSCore Runtime Framework is an experiment in pushing the boundaries of the Python environment and language features in the Pythonista 3 IDE and apps developed with it on iOS. It is an extensive Python 3 mapping of the JavaScriptCore Objective-C and C-APIs via objc-util. Implementing closely analogous Python integrations, wrapping and interop for evaluating JavaScript and WebAssembly in independent and composable JavaScriptCore execution environments from Python 3 applications and scripts. Focused also from a point of view of being a serious attempt to extend vanilla Pythonista 3 to ultimately support Python packages and modules with compiled extensions that can be cross-compiled reliably into WebAssembly. 
+JSCore Runtime Framework is an experiment in pushing the boundaries of the Python environment and language features in the [Pythonista 3 IDE](https://omz-software.com/pythonista/) and apps developed with it on iOS. It is an extensive Python 3 mapping of the JavaScriptCore Objective-C and C-APIs via objc-util. Implementing closely analogous Python integrations, wrapping and interop for evaluating JavaScript and WebAssembly in independent and composable JavaScriptCore execution environments from Python 3 applications and scripts. Focused also from a point of view of being a serious attempt to extend vanilla Pythonista 3 to ultimately support Python packages and modules with compiled extensions that can be cross-compiled reliably into WebAssembly. 
 
 The projects overall long term goals aim to offer three core capabilities/features:
 - Evaluate/execute JavaScript and WebAssembly with seamless Python interop as a standalone library for Pythonista 3 based Python 3 apps.
 - Compile, bundle, import and run custom source code and third party components extensibly with WebAssembly and JavaScript.
 - Support Python packages/modules with extensions which can be cross-compiled to WebAssmembly from languages such as C.
