 # Exercism Python Representer
 
-An [automated anaylsis](analyis) tool that parses a Python file to create a normalized `representation.txt` file per the [representer interface][interface].
+An [automated analysis][analysis] tool that parses a Python file to create a normalized `representation.txt` file per the [representer interface][interface].
+
+
+# Creating A Representation
+
+
+The Representer is run with `./bin/run.sh` `<exercise-slug>` `<path/to/solution/dir/` `</path/to/output/dir/>` and will read the source code from `<path/to/solution/dir/>` and write a representation to`</path/to/output/dir/>`.
 
-It is run with `./bin/run.sh $EXERCISM $PATH_TO_FILES $PATH_FOR_OUTPUT` and will read the source code from `$PATH_TO_FILES` and write a representation to`$PATH_FOR_OUTPUT`.
 
 For example:
 
 ```bash
 ./bin/run.sh two_fer ~/solution-238382y7sds7fsadfasj23j/ ~/solution-238382y7sds7fsadfasj23j/output/
 ```
 
- 
+
+**Please Note**:  When using the `run-in-docker.sh` script, the paths `<path/to/solution/dir/>` and `</path/to/output/dir/>` need to be _**relative**_ to the location of this repo in your local environment.
+
+
+For example:
+
+```bash
+./bin/run-in-docker.sh acronym ../python/exercises/practice/acronym/ ../python/exercises/practice/acronym/
+```
+
+Either of these commands/methods should produce the following three files in `</path/to/output/dir/>`:
+
+1.  `mapping.json`, which maps the variable names to their placeholder values.
+2.  `representation.out` - an AST representation of the solution code.
+3.  `representation.txt` - the transformed solution code with placeholders.
+
+
+
+# Running the Tests for the Representer
+
+To run all of the current tests:
+
+1. Ensure you have a copy of `pytest 7.2.2` installed globally, or in a virtual env.
+2. Ensure you have Python 3.11.2 installed globally, or in a virtual env.
+3. Open a terminal in the root of your local copy of this project.
+4. Run `pytest` or `pytest -v`
