+## Description
+This file is a documentation for the unit parameters database, which defines groups
+of general aspects, such as stats and maximum HP, of game "live" units (currently, players only).
+The groups defined in this file should later be linked in other dbs.
+
+It explains the following database files:
+- [db/pre-re/unit_parameters_db.conf](../db/pre-re/unit_parameters_db.conf)
+- [db/re/unit_parameters_db.conf](../db/re/unit_parameters_db.conf)
+
+
+> **Note:** Currently, this database is only used by Job Database in order to define
+> some differences between jobs stats.
+>

+
+## Entry structure
+```
+<Group Name>: {
+	Inherit: "<Another Group Name>"    (string, optional, default: no inheritance)
+	NaturalHealWeightRate: <value>     (int)
+	MaxASPD: <value>                   (int)
+	MaxHP: <value>                     (int) (can be groupped by level ranges)
+	MaxStats: <value>                  (int)
+}
+```
+
+--------------------------------------------------------------
+
+## Field explanation
+
+### Group Name
+The key that uniquely identify this group.
+
+It is used whenever we have to reference it, for example:
+- For `Inherit` field when inheriting it in another group
+- When linking it to a job in JobDB (`ParametersGroup` field)
+
+The value of this field should be unique in the entire db.
+
+
+### Inherit
+When defined, it copies all the values of the other group.
+
+This is the first field checked when creating a new group, thus any other definitions
+for this group will override the previously inherited value.
+
+This field is optional, and when not informed will simply be ignored (no inheritance).
+
+
+### NaturalHealWeightRate
+For players, the percent of weight at which natural healing is blocked.
+
+A value of `50` would mean that once this unit reaches 50% of weight, it will no longer
+heal automatically until it reduces some weight.
+
+The value must be between `1` and `101`, where `101` will disable this restriction.
+
+
+### MaxASPD
+The maximum ASPD (Attack speed) this unit may reach. After this value is reached,
+any further increments in ASPD is ignored.
+
+The value must be between `100` and `199`.
+
+
+### MaxHP
+The maximum HP this unit may reach. After this value is reached, any further increases in MaxHP
+is ignored.
+
+> **Note:** This is **NOT** the default class MaxHP, but how much the class' MaxHP may be increased
+> with items/stats/etc.
+>
+
+This configuration may be provided in 2 different ways:
+
+As a single, flat value:
+```
+	MaxHP: 1_000_000
+```
+
+Would mean that the unit using this group may go up to 1,000,000 HP, regardless of its level.
+
+Another option is to group it by level ranges:
+```
+	MaxHP: {
+		Lv99: 330_000     // From Level 1 to Level 99
+		Lv150: 660_000    // From Level 100 to Level 150
+		Lv175: 1_100_000  // From Level 151 to Level 175 to "Max Level"
+	}
+```
+
+In this case, each level specified in the `Lv<number>` format will be used as the upper
+limit level for this MaxHP value.
+
+> **NOTE:** The highest level defined in the group (in the example above, Lv175) will be expanded
+> to `MAX_LEVEL` during startup in order to cover missing levels.
+>
+> In other words, if your server's `MAX_LEVEL` was set to 200, using the above configuration would
+> make units between level 176 and 200 to have the same limit as units between level 151 and 175
+> (`Lv175` config "becomes" `Lv200`).
+>
+
+
+### MaxStats
+The maximum value a single stat (STR, AGI, DEX, VIT, INT, LUK) may have.
+
+The value must be between `10` and `10_000`.
