You can invoke it directly, with a complete path, and it will work even if
it's not in your $PATH variable. In my personal installation I have context
at `/home/andi/Apps/lmtx/tex/texmf-linux-64/bin`, so I can call it saying
`/home/andi/Apps/lmtx/tex/texmf-linux-64/bin/context hello-world.tex` and
Hello,
I have installed ConTeXt on my Raspberry Pi 400 (aarch64), tried to typeset
this simple file:
```
\starttext
First tex file to make, hello, world!
\stoptext
```
but the test failed:
```
$context hello-world.tex
