+# Building Upstream
+
+monero_c contains its own fork of contrib/depends system that is independent of monero, wownero or zano. In order to use said build system one needs to:
+
+```
+pushd contrib/depends
+env -i \
+PATH="$PATH" \
+CC=gcc CXX=g++ \
+make -j$(nproc) HOST=aarch64-apple-darwin
+popd
+```
+
+Then, get path to your desired toolchain.cmake
+
+```
+TOOLCHAIN_FILE=${PWD}/contrib/depends/aarch64-apple-darwin/share/toolchain.cmake
+```
+And finally use that as part of cmake invocation, for example to compile monero you can do the following:
+
+```
+pushd monero
+mkdir -p build/aarch64-apple-darwin
+cd $_
+cmake \
+-DCMAKE_TOOLCHAIN_FILE="$TOOLCHAIN_FILE" \
+-DBUILD_TESTS=ON \
+../..
+```
+
+From there you can build targets such as wallet_api
+
+```
+make wallet_api -j$(nproc)
+```
