+
+## Docker static builds
+
+Static builds via Docker are done in 3 steps:
+
+1. Cloning this repository (+submodules)
+2. Creating a base Docker image
+3. Using the base image to compile a build
+
+### Windows
+
+The docker image for Windows static compiles uses Ubuntu 18.04 and installs [mxe](https://mxe.cc) from [our git](https://git.wownero.com/feather/mxe/src/branch/feather-patch), 
+which comes with: OpenSSL 1.1.1g, Qt 5.15.0 (OpenGL via mesa). For more information, check the Dockerfile: `Dockerfile_windows`.
+
+#### 1. Clone
+
+```bash
+git clone --recursive https://git.wownero.com/feather/feather.git
+cd feather
+```
+
+#### 2. Base image
+
+Warning: Building the MXE base image takes up to a hour, so go watch a movie.
+
+```bash
+docker build -f Dockerfile_windows --tag feather:win --build-arg THREADS=8 .
+```
+
+Note: You only need to build the base image once.
+
+#### 3. Build
+
+```bash
+docker run --rm -it -v /tmp/ccache:/root/.ccache -v /root/feather:/feather -w /feather feather:win /bin/bash -c 'PATH=/mxe/usr/bin/:$PATH make windows-mxe-release -j8'
+```
+
+Replace `PATH_TO_FEATHER` with the absolute path to Feather locally. 
+
+The resulting binary can be found in `build/bin/feather.exe`.
+
+### Linux
+
+The docker image for Linux static compiles uses Ubuntu 18.04 and compiles the required libraries statically so that 
+the resulting Feather binary is static. It comes with OpenSSL 1.1.1g, Qt 5.15.0 (OpenGL disabled). For more information, 
+check the Dockerfile: `Dockerfile`.
+
+#### 1. Clone
+
+```bash
+git clone --recursive https://git.wownero.com/feather/feather.git
+cd feather
+```
+
+#### 2. Base image
+
+Warning: Building the base image takes a while, go prepare some dinner.
+
+```bash
+docker build --tag feather:linux --build-arg THREADS=8 .
+```
+
+Note: You only need to build the base image once.
+
+#### 3. Build
+
+```bash
+docker run --env OPENSSL_ROOT_DIR=/usr/local/openssl/ --rm -it -v /tmp/ccache:/root/.ccache -v PATH_TO_FEATHER:/feather -w /feather feather:linux sh -c 'make release-static -j8'
+```
+
+Replace `PATH_TO_FEATHER` with the absolute path to Feather locally.
+
+The resulting binary can be found in `build/bin/feather`.
+
+## macOS
+
+For MacOS it's easiest to leverage [brew](https://brew.sh) to install the required dependencies. 
+
+```bash
+HOMEBREW_OPTFLAGS="-march=core2" HOMEBREW_OPTIMIZATION_LEVEL="O0" \
+    brew install boost zmq openssl libpgm miniupnpc libsodium expat libunwind-headers protobuf libgcrypt qrencode ccache cmake pkgconfig git
+```
+
+Clone the repository.
+
+```bash
+git clone --recursive https://git.wownero.com/feather/feather.git
+``` 
+
+Get the latest LTS from here: https://www.qt.io/offline-installers and install.
+
+Build Feather.
+
+```bash
+CMAKE_PREFIX_PATH=~/Qt5.15.1/5.15.1/clang_64 make mac-release
+```
+
+The resulting Mac OS application can be found `build/bin/feather.app`.

+# Documentation for developers
+
+Feather is developed primarily on Linux. It uses Qt 5.15.* and chances are that your 
+distro's package manager has a lower version. It is therefore recommended that you install 
+Qt manually using the online installer, which can be found here: https://www.qt.io/download 
+(under open-source).
+
+## Jetbrains Clion
+
+Feather was developed using JetBrains Clion since it integrates nicely 
+with CMake and comes with a built-in debugger. To pass CMake flags to CLion, 
+go to `File->Settings->Build->CMake`, set Build Type to `Debug` and set your 
+preferred CMake options/definitions.
+
+## Requirements
+
+### Ubuntu/Debian
+
+```bash
+apt install -y git cmake libqrencode-dev build-essential cmake libboost-all-dev \
+miniupnpc libunbound-dev graphviz doxygen libunwind8-dev pkg-config libssl-dev \
+libzmq3-dev libsodium-dev libhidapi-dev libnorm-dev libusb-1.0-0-dev libpgm-dev \
+libprotobuf-dev protobuf-compiler libgcrypt20-dev
+```
+
+## Mac OS
+
+```bash
+brew install boost zmq openssl libpgm miniupnpc libsodium expat libunwind-headers \
+protobuf libgcrypt qrencode ccache cmake pkgconfig git
+```
+
+## CMake
+
+After installing Qt you might have a folder called `/home/$user/Qt/`. You need to pass this to CMake 
+via the `CMAKE_PREFIX_PATH` definition. For me this is:
+
+```
+-DCMAKE_PREFIX_PATH=/home/dsc/QtNew/5.15.0/gcc_64
+```
+
+There are some Monero/Feather related options/definitions that you may pass:
+
+- `-DXMRTO=OFF` - disable Xmr.To feature
+- `-DBUILD_TOR=OFF` - disable embedded Tor
+- `-DDONATE_BEG=OFF` - disable the dreaded donate requests
+
+And:
+
+```
+-DMANUAL_SUBMODULES=1  
+-DUSE_DEVICE_TREZOR=OFF 
+-DUSE_SINGLE_BUILDDIR=ON 
+-DDEV_MODE=ON 
+```
+
+If you have OpenSSL installed in a custom location, try:
+
+```
+-DOPENSSL_INCLUDE_DIR=/usr/local/lib/openssl-1.1.1g/include 
+-DOPENSSL_SSL_LIBRARY=/usr/local/lib/openssl-1.1.1g/libssl.so.1.1 
+-DOPENSSL_CRYPTO_LIBRARY=/usr/local/lib/openssl-1.1.1g/libcrypto.so.1.1
+```
+
+I prefer also enabling verbose makefiles, which may be useful in some situations.
+
+```
+-DCMAKE_VERBOSE_MAKEFILE=ON
+```
+
+Enable debugging symbols:
+
+```bash
+-DCMAKE_BUILD_TYPE=Debug
+```
+
+## Feather
+
+It's best to install Tor locally as a service and start Feather with `--use-local-tor`, this 
+prevents the child process from starting up and saves time.
+
+#### Ubuntu/Debian
+
+```bash
+apt install -y tor
+sudo service tor start
+```
+
+#### Mac OS
+
+```bash
+brew install tor
+brew services start tor
+```
+
+To skip the wizards and open a wallet directly use `--wallet-file`: 
+
+```bash
+./feather --use-local-tor --wallet-file /home/user/Monero/wallets/bla.keys
+```
+
+It is recommended that you use `--stagenet` for development. Testnet is also possible, 
+but you'll have to provide Feather a testnet node of your own.

+# Feather - a free Monero desktop wallet 
+
+[![Build Status](https://build.featherwallet.org/api/badges/feather/feather/status.svg)](https://build.featherwallet.org/feather/feather)
+
+Feather is a free, open-source Monero client for Mac OS and Linux platforms written in C++ with the Qt framework. It is created and maintained by [dsc](dsc@xmr.pm) and [tobtoht](thotbot@protonmail.com).
+
+## Development resources
+* Web: [featherwallet.org](https://featherwallet.org)
+* Git: [git.wownero.com/feather/feather](https://git.wownero.com/feather/feather)
+* IRC: `#feather` on OFTC
+* Development builds: [build.featherwallet.org/files](https://build.featherwallet.org/files/)
+
+Copyright (c) 2020-2021 The Monero Project.
+
+## Compiling Feather from source
+
+Feather uses Monero, as such it requires the same dependencies as outlined in [Monero's README](https://github.com/monero-project/monero#compiling-monero-from-source). Additionally, Feather uses:
+
+- Qt 5.15.0
+- libqrencode
+- openpgp
+
+See [BUILDING.md](https://git.wownero.com/feather/feather/src/branch/master/BUILDING.md) for information on how to compile a build.
+
+## Supporting the project
+
+Feather is a 100% community-sponsored endeavor. If you want to join our efforts, the easiest thing you can do is support the project financially.

+
+## Developers
+
+See [HACKING.md](https://git.wownero.com/feather/feather/src/branch/master/HACKING.md) for useful development resources.
+
+It is HIGHLY recommended that you join the `#feather` IRC channel on OFTC if you are hacking on Feather. Due to the nature of this open source software project, joining this channel and idling is the best way to stay updated on best practices and new developments.
