 This ["first come, first assign"](https://github.com/multiformats/multicodec/pull/16#issuecomment-260146609) policy is a way to assign codes as they are most needed, without increasing the size of the table (and therefore the size of the multicodecs) too rapidly.
 
-The first 127 bits are encoded as a single-byte varint, hence they are reserved for the most widely used multicodecs. So if you are adding your own codec to the table, you most likely would want to ask for a codec bigger than `0x80`.

 Codec names should be easily convertible to constants in common programming languages using basic transformation rules (e.g. upper-case, conversion of `-` to `_`, etc.). Therefore they should contain alphanumeric characters, with the first character being alphabetic. The primary delimiter for multi-part names should be `-`, with `_` reserved for cases where a secondary delimiter is required. For example: `bls12_381-g1-pub` contains 3 parts: `bls12_381`, `g1` and `pub`, where `bls12_381` is "BLS12 381" which is not commonly written as "BLS12381" and therefore requires a secondary separator.
