This will build both the Rust and Python codebase and install it into your locally activated conda environment. While not required, if you have updated dependencies for Rust you might prefer a clean build. To clean your setup run ```python setup.py clean``` and then run ```python setup.py install```

 ### Datastructures
 While working in the Rust codebase there are a few datastructures that you should make yourself familiar with. This section does not aim to verbosely list out all of the datastructure with in the project but rather just the key datastructures that you are likely to encounter while working on almost any feature/issue. The aim is to give you a better overview of the codebase without having to manually dig through the all the source code.
 
-- [`PyLogicalPlan`](dask_planner/src/sql/logical.rs) -> [DataFusion LogicalPlan](https://docs.rs/datafusion/latest/datafusion/logical_plan/enum.LogicalPlan.html)
+- [`PyLogicalPlan`](src/sql/logical.rs) -> [DataFusion LogicalPlan](https://docs.rs/datafusion/latest/datafusion/logical_plan/enum.LogicalPlan.html)
     - Often encountered in Python code with variable name `rel`
     - Python serializable umbrella representation of the entire LogicalPlan that was generated by DataFusion
     - Provides access to `DaskTable` instances and type information for each table
     - Access to individual nodes in the logical plan tree. Ex: `TableScan`
-- [`DaskSQLContext`](dask_planner/src/sql.rs)
+- [`DaskSQLContext`](src/sql.rs)
     - Analogous to Python `Context`
     - Contains metadata about the tables, schemas, functions, operators, and configurations that are persent within the current execution context
     - When adding custom functions/UDFs this is the location that you would register them
     - Entry point for parsing SQL strings to sql node trees. This is the location Python will begin its interactions with Rust
-- [`PyExpr`](dask_planner/src/expression.rs) -> [DataFusion Expr](https://docs.rs/datafusion/latest/datafusion/prelude/enum.Expr.html)
+- [`PyExpr`](src/expression.rs) -> [DataFusion Expr](https://docs.rs/datafusion/latest/datafusion/prelude/enum.Expr.html)
     - Arguably where most of your time will be spent
     - Represents a single node in sql tree. Ex: `avg(age)` from `SELECT avg(age) FROM people`
     - Is associate with a single `RexType`
     - Can contain literal values or represent function calls, `avg()` for example
     - The expressions "index" in the tree can be retrieved by calling `PyExpr.index()` on an instance. This is useful when mapping frontend column names in Dask code to backend Dataframe columns
     - Certain `PyExpr`s contain operands. Ex: `2 + 2` would contain 3 operands. 1) A literal `PyExpr` instance with value 2 2) Another literal `PyExpr` instance with a value of 2. 3) A `+` `PyExpr` representing the addition of the 2 literals.
-- [`DaskSqlOptimizer`](dask_planner/src/sql/optimizer.rs)
+- [`DaskSqlOptimizer`](src/sql/optimizer.rs)
     - Registering location for all Dask-SQL specific logical plan optimizations
     - Optimizations that are written either custom or use from another source, DataFusion, are registered here in the order they are wished to be executed
     - Represents functions that modify/convert an original `PyLogicalPlan` into another `PyLogicalPlan` that would be more efficient when running in the underlying Dask framework
-- [`RelDataType`](dask_planner/src/sql/types/rel_data_type.rs)
+- [`RelDataType`](src/sql/types/rel_data_type.rs)
     - Not a fan of this name, was chosen to match existing Calcite logic
     - Represents a "row" in a table
     - Contains a list of "columns" that are present in that row
-        - [RelDataTypeField](dask_planner/src/sql/types/rel_data_type_field.rs)
-- [RelDataTypeField](dask_planner/src/sql/types/rel_data_type_field.rs)
+        - [RelDataTypeField](src/sql/types/rel_data_type_field.rs)
+- [RelDataTypeField](src/sql/types/rel_data_type_field.rs)
     - Represents an individual column in a table
     - Contains:
         - `qualifier` - schema the field belongs to
         - `name` - name of the column/field
         - `data_type` - `DaskTypeMap` instance containing information about the SQL type and underlying Arrow DataType
         - `index` - location of the field in the LogicalPlan
-- [DaskTypeMap](dask_planner/src/sql/types.rs)
+- [DaskTypeMap](src/sql/types.rs)
     - Maps a conventional SQL type to an underlying Arrow DataType
