+## Pro Micro Hacking
-Userspace EEPROM config
------------------------
-
-This adds EEPROM support fo the userspace, so that certain values are configurable in such a way that persists when power is lost.  Namely, just the clicky feature and the Overwatch macro option ("is_overwatch").  This is done by reading and saving the structure from EEPROM. 
-
-To implement this, first you need to specify the location:
-
-```c
-#define EECONFIG_USERSPACE (uint8_t *)20
-```
-This tells us where in the EEPROM that the data structure is located, and this specifies that it's a byte (8 bits).  However, to maximize it's usage, we want to specify a data structure here, so that we can use multiple settings.  To do that:
-
-```c
-typedef union {
-  uint8_t raw;
-  struct {
-    bool     clicky_enable  :1;
-    bool     is_overwatch   :1;
-  };
-} userspace_config_t;
-```
-Then, in your C file, you want to add: `userspace_config_t userspace_config;`, and in your `matrix_init_*` function, you want to add `userspace_config.raw = eeprom_read_byte(EECONFIG_USERSPACE);`
-
-From there, you'd want to use the data structure (such as `userspace_config.is_overwatch`) when you want to check this value.  
-
-And if you want to update it, update directly and then use `eeprom_update_byte(EECONFIG_USERSPACE, userspace_config.raw);` to write the value back to the EEPROM.
