-Termux is a terminal application and Linux environment that you can also use to
-run code-server from your Android phone.
+### Install
 
-## Install
+1. Get [Termux](https://f-droid.org/en/packages/com.termux/) from **F-Droid**.
+2. Install Debian by running the following. - Run `termux-setup-storage` to allow storage access, or else code-server won't be able to read from `/sdcard`.\
+    If you used the Andronix command \\/ then you may have to edit the `start-debian.sh` script to mount `/sdcard` just as simple as uncommenting the `command+=" -b /sdcard"` line.
+   > The following command was extracted from [Andronix](https://andronix.app/) you can also use [proot-distro](https://github.com/termux/proot-distro).
 
-1. Install Termux from [F-Droid](https://f-droid.org/en/packages/com.termux/).
-1. Make sure it's up-to-date: `apt update && apt upgrade`
-1. Install required packages: `apt install build-essential python git nodejs-lts yarn`
-1. Install code-server: `yarn global add code-server`
-1. Run code-server: `code-server` and navigate to localhost:8080 in your browser
+```bash
+pkg update -y && pkg install wget curl proot tar -y && wget https://raw.githubusercontent.com/AndronixApp/AndronixOrigin/master/Installer/Debian/debian.sh -O debian.sh && chmod +x debian.sh && bash debian.sh
+```
 
-## Upgrade
+> After Debian is installed the `~ $` will change to `root@localhost`. 3. Run the following commands to setup Debian.
 
-To upgrade run: `yarn global upgrade code-server --latest`
+```bash
+apt update
+apt upgrade -y
+apt-get install nano vim sudo curl wget git -y
+```
 
-## Known Issues
+4. Then create a new user to use later and change its password.
 
-The following details known issues and suggested workarounds for using
-code-server with Termux.
+```bash
+useradd username -m
+passwd username
+```
 
-### Search doesn't work
+5. Install [NVM](https://github.com/nvm-sh/nvm) by following the install guide in the README, just a curl/wget command.
+6. Set up NVM for multi-user. After installing NVM it automatically adds the necessary commands for it to work, but it will only work if you are logged in as root; which we do not want (see step 9) so do the following things.
 
-There is a known issue with search not working on Android because it's missing
-`bin/rg` ([context](https://github.com/cdr/code-server/issues/1730#issuecomment-721515979)). To fix this:
+   - Copy the lines NVM asks you to run after running the install script.
+   - Run `nano /root/.bashrc` and comment out those lines by adding a `#` at the start.
+   - Run `nano /etc/profile` and paste those lines at the end and make sure to replace `$HOME` with `/root`
+   - Now run `exit` and start Debain again.
 
-1. Install `ripgrep` with `pkg`
+7. After following the instructions and setting up NVM you can now install the [required node version](https://coder.com/docs/code-server/latest/npm#nodejs-version) using `nvm install version_here`.
+8. You don't need to install yarn.
+9. Now you are ready to install code-server, but let's switch users first.
+   - There are many answers on Stack Exchange for why logging in as root is not recommended,\
+     but here's a [short article](https://www.howtogeek.com/124950/htg-explains-why-you-shouldnt-log-into-your-linux-system-as-root/) for you.
+   - Run the following `visudo` to give your user (created in step 4) sudo privileges.
+   - After executing the command, scroll to `User privilege specification` and add `username ALL=(ALL:ALL) ALL`.
+10. To switch users, run `su - username`. **DO NOT forget to add the `-` between `su` and the username or, else the `/etc/profile` file won't be executed,** you may instead follow step 6 but edit the `/etc/bash.bashrc` file instead of `/etc/profile` if you don't want to add a `-` between `su` and username.
 
-   ```sh
-   pkg install ripgrep
-   ```
+11. To install `code-server` run the following.
 
-1. Make a soft link using `ln -s`
+To check the install process (Will not actually install code-server)
 
-   ```sh
-   # run this command inside the code-server directory
-   ln -s $PREFIX/bin/rg ./vendor/modules/code-oss-dev/vscode-ripgrep/bin/rg
-   ```
+```bash
+curl -fsSL https://code-server.dev/install.sh | sh -s -- --dry-run
+```
 
-### Backspace doesn't work
+If all looks good, you can run to install code-server.
 
-When using Android's on-screen keyboard, the backspace key doesn't work
-properly. This is a known upstream issue:
+```bash
+curl -fsSL https://code-server.dev/install.sh | sh
+```
 
-- [Issues with backspace in Codespaces on Android (Surface Duo)](https://github.com/microsoft/vscode/issues/107602)
-- [Support mobile platforms](https://github.com/xtermjs/xterm.js/issues/1101)
+12. Every time you run `./start-debian.sh` (or `proot-distro login debian` if you used proot-distro), you can switch to your user `su - username` and run code-server.
 
-There are two workarounds.
+### Upgrade
 
-**Option 1:** Modify keyboard dispatch settings
+1. Remove all previous installs `rm -rf ~/.local/lib/code-server-*`
+2. Run the install script again `curl -fsSL https://code-server.dev/install.sh | sh`
 
-1. Open the Command Palette
-2. Search for **Preferences: Open Settings (JSON)**
-3. Add `"keyboard.dispatch": "keyCode"`
+### Known Issues
 
-The backspace button should work at this point.
+#### Git won't work in `/sdcard`
 
-_Thanks to @Nefomemes for the [suggestion](https://github.com/cdr/code-server/issues/1141#issuecomment-789463707)!_
+Issue : Using git in the `/sdcard` directory will fail during cloning/commit/staging/etc...\
+Fix : None\
+Potential Workaround :
 
-**Option 2:** Use a Bluetooth keyboard.
+1. Create a soft-link from the debian-fs to your folder in `/sdcard`
+2. Use git from termux (preferred)
+
+### Extra
+
+#### Install GO
+
+> From https://golang.org/doc/install
+
+1. Go to https://golang.org/dl/ and copy the download link for `linux arm` and run the following.
+
+```bash
+wget download_link
+```
+
+2. Extract the downloaded archive. (This step will erase all previous GO installs, make sure to create a backup if you have previously installed GO)
+
+```bash
+rm -rf /usr/local/go && tar -C /usr/local -xzf archive_name
+```
+
+3. Run `nano /etc/profile` and add the following line `export PATH=$PATH:/usr/local/go/bin`.
+4. Now run `exit` (depending on if you have switched users or not, you may have to run `exit` multiple times to get to normal termux shell) and start Debian again.
+5. Check if your install was successful by running `go version`
+
+#### Install Python
+
+> Run these commands as root
+
+1. Run the following command to install required packages to build python.
+
+```bash
+sudo apt-get update
+sudo apt-get install make build-essential libssl-dev zlib1g-dev \
+  libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm \
+  libncursesw5-dev xz-utils tk-dev libxml2-dev libxmlsec1-dev libffi-dev liblzma-dev
+```
+
+2. Install [pyenv](https://github.com/pyenv/pyenv/) from [pyenv-installer](https://github.com/pyenv/pyenv-installer) by running.
+
+```bash
+curl -L https://github.com/pyenv/pyenv-installer/raw/master/bin/pyenv-installer | bash
+```
+
+3. Run `nano /etc/profile` and add the following
+
+```bash
+export PYENV_ROOT="/root/.pyenv"
+export PATH="/root/.pyenv/bin:$PATH"
+eval "$(pyenv init --path)"
+eval "$(pyenv virtualenv-init -)"
+```
+
+4. Exit start Debian again.
+5. Run `pyenv versions` to list all installable versions.
+6. Run `pyenv install version` to install the desired python version.
+   > The build process may take some time (an hour or 2 depending on your device).
+7. Run `touch /root/.pyenv/version && echo "your_version_here" > /root/.pyenv/version`
+8. (You may have to start Debian again) Run `python3 -V` to verify if PATH works or not.
+   > If `python3` doesn't work but pyenv says that the install was successful in step 6 then try running `$PYENV_ROOT/versions/your_version/bin/python3`.
+9. You can now switch users by `su - username` and try running `python3 -V` and `pip -V` to check if it works or not.
