 ## Installation
-NodeMCU PyFlasher doesn't have to be installed, just double-click it and it'll start. Check the [releases section](https://github.com/marcelstoer/nodemcu-pyflasher/releases) for downloads for your platform. For every release there's at least a .exe file for Windows. Starting from 3.0 there's also a .dmg for macOS.

 ## Status
 Scan the [list of open issues](https://github.com/marcelstoer/nodemcu-pyflasher/issues) for bugs and pending features.

-**Note**
+- Due to [pyinstaller/pyinstaller#2355](https://github.com/pyinstaller/pyinstaller/issues/2355) I can't provide an app bundle for macOS yet. The PyInstaller `.spec` file and the build script are ready, though. Of course you can still *run* the application on macOS. Clone this repo and then do `python nodemcu-pyflasher.py` (see "[Build it yourself](#build-it-yourself)" for pre-requisits).

+**Note** 

 This is my first Python project. If you have constructive feedback as for how to improve the code please do reach out to me.

 ## Build it yourself
 If you want to build this application yourself you need to:

- Install [Python 3.x](https://www.python.org/downloads/) and [Pip](https://pip.pypa.io/en/stable/installing/) (it comes with Python if installed from `python.org`).
- Create a virtual environment with `python -m venv venv`
- Activate the virtual environment with `. venv/bin/activate` (`. venv/Scripts/activate` if you are on Windows with [Cygwin](https://www.cygwin.com/) or [Mingw](http://mingw.org/))
- Run `pip install -r requirements.txt`
-
-**A note on Linux:** As described on the [downloads section of `wxPython`](https://www.wxpython.org/pages/downloads/), wheels for Linux are complicated and may require you to run something like this to install `wxPython` correctly:
-
-```bash
-# Assuming you are running it on Ubuntu 18.04 LTS with GTK3
-pip install -U \
-    -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-18.04 \
-    wxPython
-```
+- Install Python
+- Install [wxPython 3.x](https://sourceforge.net/projects/wxpython/files/wxPython/) (not 4.0 betas!)
+- Install [esptool.py](https://github.com/espressif/esptool#easy-installation) which brings pySerial or install pySerial standalone

+If esptool.py is installed using python setup.py` from a checked out version it creates something like the following
+in the Python environment
+
+esptool.py file containing
+
+#!/usr/local/opt/python/bin/python2.7
+# EASY-INSTALL-SCRIPT: 'esptool==1.3.dev0','esptool.py'
+__requires__ = 'esptool==1.3.dev0'
+__import__('pkg_resources').run_script('esptool==1.3.dev0', 'esptool.py')
+
+PyInstaller (and cx_Freeze) doesn't support pkg_resources and complains about 'ImportError: "No module named
+pkg_resources"'. This can be avoided if the application maintains a local copy of esptool.py.
