 ## Setup
-### Getting ncurses with termcap
-You need `termcap` to build the Proxmark3 client. Unfortunately, the prebuilt `ncurses` package does not include it. Since [this PR](https://github.com/termux/termux-packages/pull/2131) hasn't been merged yet, you will have to build `ncurses` yourself
-
-1. Clone the [termux-packages](https://github.com/termux/termux-packages) repo
-2. Apply [the PR](https://github.com/termux/termux-packages/pull/2131)
-3. Build `ncurses`. Refer to the [build docs](https://github.com/termux/termux-packages/blob/master/docs/BUILD_ENVIRONMENT.md) for more information. The easiest way is to use Docker:
-    - `./scripts/run-docker.sh`
-    - `./build-package.sh ncurses`
-    - the built packages will be under the `debs` directory
-4. Copy `ncurses_6.1.x-x_aarch64.deb` to your phone's `/sdcard`
 ### Setting up Termux
 1. Install [Termux](https://play.google.com/store/apps/details?id=com.termux) and start it
 2. Run the following commands:
 ```
-pkg install make, clang, clang++, readline-dev, libclang-dev, libc++, git, tsu
-termux-setup-storage
-dpkg -i /sdcard/ncurses_6.1.x-x_aarch64.deb
+pkg install make clang clang++ readline libc++ git tsu
 git clone https://github.com/RfidResearchGroup/proxmark3.git
 ```
 ### Building Proxmark3 client
-1. Edit `proxmark3/client/Makefile` and append `-fPIC` to the `CFLAGS` variable (line 30)
-2. `make clean && make client`
+1. `make clean && make client`
 
 ### USB_ACM
 You need the `USB_ACM` driver enabled and working to communicate with the Proxmark3. To see if it's working, run `tsudo ls /dev/tty*` and it should list `/dev/ttyACM0` (or similar). If you see this, congratulations, skip this step!
