# Structure
The instructions for installing Pixelator involve downloading the code into the `/home/control/work/stxm/` directory. To allow the installation of multiple versions, it is best to put each version in a new directory in `work/` and make a _stxm_ soft link that points to the one you wish to use such that the startup scripts will still work the same. For example:
```
control@pixelator-1:~/work$ ls -l
total 20
drwxr-xr-x 14 control control 4096 Jul 7 11:20 stxm-20250520
drwxr-xr-x 14 control control 4096 Aug 22 15:07 stxm-20250822
lrwxrwxrwx 1 control control 13 Jul 4 22:54 stxm -> stxm-20250520
```
At PolLux, we use 2 different links together with startup scripts for a _stxm-stable_ and a _stxm-test_ version:
```
control@x07da-stxm-1:~/work$ ls -l
total 20
drwxr-xr-x 14 control control 4096 Feb 3 2025 stxm
drwxr-xr-x 14 control control 4096 Jul 7 11:20 stxm-20250520
drwxr-xr-x 14 control control 4096 Aug 13 17:30 stxm-20250702-russ
drwxr-xr-x 14 control control 4096 Aug 13 18:02 stxm-20250813-russ
drwxr-xr-x 14 control control 4096 Aug 22 15:07 stxm-20250822
lrwxrwxrwx 1 control control 13 Jul 4 22:54 stxm-stable -> stxm-20250520
lrwxrwxrwx 1 control control 20 Aug 13 17:33 stxm-test -> ./stxm-20250813-russ
```
# Download New Code
The new code can be downloaded from `gitea.psi.ch`. There are 3 ways to do this:
1. Use the `git clone` command with an **https** link - requires a token from gitea.psi.ch
2. Use the `git clone` command with an **ssh** link - requires uploading your public key to gitea.psi.ch
3. Log in to gitea.psi.ch and use the blue `<> code` button menu to download a ZIP or TAR.GZ archive
# Activate a Different Version
A different version can be made active by redirecting the link to point at the directory of the desired version. From the `~/work/` directory, use the command:
```ln -sf $TARGET $LINK_NAME```
where `$TARGET` is the directory name of the desired version and $LINK_NAME is the path that your startup scripts expect (e.g. `stxm` or `stxm-test`).
