+- Interactive input is not supported yet, so currently division-by-zero throws a runtime error.
+- `g` and `p` calls that access coordinates outside of the 80x25 grid result in a runtime error.

-- For Turing-completeness, the number of cells is kept unbounded.
+- The tape is semi-unbounded (0, 1, 2 ...)
 - Cell size is 8 bits, and allows values in the range `[-128, 127]`.
 - Value `10` is designated for newlines.
 - The value `0` is returned on reaching `EOF`.

 # Chef
 
-- Ingredient names are case-sensitive and must not contain periods.
+## References
+
+- David Morgan-Mar's Chef page: https://www.dangermouse.net/esoteric/chef.html
+
+## Implementation details
+
+- Ingredient names are case-sensitive and must contain only letters and spaces.
+
 - Auxiliary recipe names are case-sensitive. If the recipe title is `Chocolate Sauce`, calling instruction must be `Serve with Chocolate Sauce` and not `Serve with chocolate sauce`.
+
 - Each method instruction must end with a period.
-- The method section can be spread across multiple lines.
-- A single method instruction cannot roll over to the next line.
+
+- Method instructions can be located on separate lines, the same line or a mix of both. The following is a valid Chef recipe method:
+
+  ```
+  Put salt into the mixing bowl. Mix well.
+  Fold sugar into the mixing bowl. Clean the mixing bowl.
+  ```
+
+  Note that a single method instruction cannot roll over to the next line, though.
+
 - The Chef language involves usage of present and past forms of verbs:
   ```
-  Blend the sugar
+  Blend the sugar.
   <other instructions>
-  Shake the mixture until blended
+  Shake the mixture until blended.
   ```
   The Esolang Park interpreter cannot convert verbs between the two forms, so we adopt the following convention: the past form of the verb is the same as the present form of the verb. So the above example must be changed to the following for Esolang Park:
   ```
-  Blend the sugar
+  Blend the sugar.
   <other instructions>
-  Shake the mixture until blend
+  Shake the mixture until blend.
   ```
