 Download the `lxsh-linux-amd64.tar.gz` archive, extract it,
 and move the `lxsh` binary in a PATH folder (`/usr/local/bin` is the recommended).

 ## Debashify
 
-Bash specific features can be translated into POSIX code.
+Some bash specific features can be translated into POSIX shell code.
 
-This is a work in progress and for now only some are translated:
+The following bash features can be debashified:
 - `<()` and `>()` process substitutions
 - `<<<` herestring
 - `>&`, `&>` and `&>>` output redirects
+- `[[ ]]` conditions
+- indexed arrays and associative arrays (+ their `declare` and `typeset` definitions)
+
+### Advantages
+
+- Removes dependency on bash and makes a script more portable.
+- In some cases it can also provide improved performance given that some more minimalist shells like `dash` have better performance.
+  * this doesn't always apply for all situations, make sure to verify through testing
+
+### Limitations
+
+#### Process substitution
+
+The debashifying of process substitution assumes that /dev/urandom will exist and will provide proper randomness. <br>
+Temporary files with random names are used to create named pipes for the commands in the substitution.
+
+There may be some slight performance loss on the creation of said process subtitution.
+
+#### Indexed/Associative Arrays
+
+Indexed arrays and associative arrays are detected on parse instead of runtime.
+By default if an array operator is found, it is assumed to be an indexed array,
+and associative arrays are detected through the use of `declare` (or `typeset`). <br>
+In cases where there is ambiguity, the result upon execution might be undesired.
+
+> To avoid such ambiguities, put the `declare` statement of a variable first of all,
+> and don't mix and match different types on the same variable name
+
+Getting the value of an array without index will give the full value instead of the first value.
+
+> To avoid such situation, always get values from an index in your array
+
+Arrays are store as strings. Indexed arrays are delimited by tabs and associative arrays by newlines,
+This means inserting values containing these characters will have undesired behavior.
+
+Debashified arrays have substantially reduced performance.
+
+Where bash would present proper errors upon incorrectly accessing arrays,
+these features will continue working with undesired behavior.
+
+> To avoid this, make sure to never access incorrect values
+
+Array argument with `[@]` does not work with spaces, tabs and newlines in values.
