 Concatenation (||) is the operation of appending one byte sequence onto another.
 
 As standard conversion functions, we assume:
-* point(p): returns the coordinate pair resulting from EC point multiplication (repeated application of the EC group operation) of the secp256k1 base point with the integer p.
+* point(p): returns the coordinate pair resulting from EC point multiplication (repeated application of the EC group operation) of the secp256k1 base point with the integer p (i.e., the operation used to compute a public key from a private key).
 * ser<sub>32</sub>(i): serialize a 32-bit unsigned integer i as a 4-byte sequence, most significant byte first.
 * ser<sub>256</sub>(p): serializes the integer p as a 32-byte sequence, most significant byte first.
-* ser<sub>P</sub>(P): serializes the coordinate pair P = (x,y) as a byte sequence using SEC1's compressed form: (0x02 or 0x03) || ser<sub>256</sub>(x), where the header byte depends on the parity of the omitted y coordinate.
+* ser<sub>P</sub>(P): serializes the coordinate pair P = (x,y) (i.e., the public key) as a byte sequence using [https://www.secg.org/sec1-v2.pdf SEC1]'s compressed form: (0x02 or 0x03) || ser<sub>256</sub>(x), where the header byte depends on the parity of the omitted y coordinate.
 * parse<sub>256</sub>(p): interprets a 32-byte sequence as a 256-bit number, most significant byte first.
