+## Set
+
+### SADD key member [member ...]
+Add the specified members to the set stored at key. Specified members that are already a member of this set are ignored. If key does not exist, a new set is created before adding the specified members.
+
+**Return value**
+
+int64: the number of elements that were added to the set, not including all the elements already present into the set.
+
+**Examples**
+
+```
+ledis> SADD myset hello
+(integer) 1
+ledis> SADD myset world
+(integer) 1
+ledis> SADD myset hello
+(integer) 0
+ledis> SMEMBERS myset
+1) "hello"
+2) "world"
+```
+
+
+### SCARD key
+
+Returns the set cardinality (number of elements) of the set stored at key.
+
+**Return value**
+
+int64: the cardinality (number of elements) of the set, or 0 if key does not exist.
+
+**Examples**
+
+```
+ledis> SADD myset hello
+(integer) 1
+ledis> SADD myset world
+(integer) 1
+ledis> SADD myset hello
+(integer) 0
+ledis> SCARD myset
+(integer) 2
+```
+
+
+### SDIFF key [key ...]
+Returns the members of the set resulting from the difference between the first set and all the successive sets.
+For example:
+
+```
+key1 = {a,b,c,d}
+key2 = {c}
+key3 = {a,c,e}
+SDIFF key1 key2 key3 = {b,d}
+```
+
+Keys that do not exist are considered to be empty sets.
+
+
+**Return value**
+
+bulk: list with members of the resulting set.
+
+**Examples**
+
+```
+ledis> SADD key1 a b c 
+(integer) 3
+ledis> SADD key2 c d e
+(integer) 3
+ledis> SDIFF key1 key2
+1) "a"
+2) "b"
+ledis> SDIFF key2 key1
+1) "d"
+2) "e"
+```
+
+### SDIFFSTORE destination key [key ...]
+This command is equal to `SDIFF`, but instead of returning the resulting set, it is stored in destination.
+If destination already exists, it is overwritten.
+
+**Return value**
+
+int64:  the number of elements in the resulting set.
+
+**Examples**
+
+```
+ledis> SADD key1 a b c 
+(integer) 3
+ledis> SADD key2 c d e
+(integer) 3
+ledis> SDIFF key1 key2
+1) "a"
+2) "b"
+ledis> SDIFFSTORE key key1 key2
+(integer) 2
+ledis> SMEMBERS key
+1) "a"
+2) "b"
+```
+
+### SINTER key [key ...]
+
+Returns the members of the set resulting from the intersection of all the given sets.
+For example:
+
+```
+key1 = {a,b,c,d}
+key2 = {c}
+key3 = {a,c,e}
+SINTER key1 key2 key3 = {c}
+```
+
+Keys that do not exist are considered to be empty sets. With one of the keys being an empty set, the resulting set is also empty (since set intersection with an empty set always results in an empty set).
+
+**Return value**
+
+bulk: list with members of the resulting set.
+
+**Examples**
+
+```
+ledis> SADD key1 a b c 
+(integer) 3
+ledis> SADD key2 c d e
+(integer) 3
+ledis> SINTER key1 key2
+1) "c"
+ledis> SINTER key2 key_empty

+```
+
+
+### SINTERSTORE  destination key [key ...]
+
+This command is equal to `SINTER`, but instead of returning the resulting set, it is stored in destination.
+If destination already exists, it is overwritten.
+
+**Return value**
+
+int64: the number of elements in the resulting set.
+
+**Examples**
+
+```
+ledis> SADD key1 a b c 
+(integer) 3
+ledis> SADD key2 c d e
+(integer) 3
+ledis> SINTERSTORE key key1 key2
+(integer) 1
+ledis> SMEMBERS key
+1) "c"
+```
+
+
+### SISMEMBER  key member
+Returns if member is a member of the set stored at key.
+
+**Return value**
+
+Int64 reply, specifically:
+
+- 1 if the element is a member of the set.
+- 0 if the element is not a member of the set, or if key does not exist.
+
+**Examples**
+
+```
+ledis> SADD myset hello
+(integer) 1
+ledis> SISMEMBER myset hello
+(integer) 1
+ledis> SISMEMBER myset hell
+(integer) 0
+```
+
+### SMEMBERS key 
+Returns all the members of the set value stored at key.
+This has the same effect as running `SINTER` with one argument key.
+
+**Return value**
+
+bulk: all elements of the set.
+
+**Examples**
+
+```
+ledis> SADD myset hello
+(integer) 1
+ledis> SADD myset world
+(integer) 1
+ledis> SMEMBERS myset
+1) "hello"
+2) "world"
+```
+
+### SREM  key member [member ...]
+
+Remove the specified members from the set stored at key. Specified members that are not a member of this set are ignored. If key does not exist, it is treated as an empty set and this command returns 0.
+
+**Return value**
+
+int64: the number of members that were removed from the set, not including non existing members.
+
+**Examples**
+
+```
+ledis> SADD myset one
+(integer) 1
+ledis> SADD myset two
+(integer) 1
+ledis> SADD myset three
+(integer) 1
+ledis> SREM myset one

+```
+key1 = {a,b,c,d}
+key2 = {c}
+key3 = {a,c,e}
+SUNION key1 key2 key3 = {a,b,c,d,e}
+```
+Keys that do not exist are considered to be empty sets.
+
+
+**Return value**
+
+bulk: list with members of the resulting set.
+
+**Examples**
+
+```
+ledis> SMEMBERS key1
+1) "a"
+2) "b"
+3) "c"
+ledis> SMEMBERS key2
+1) "c"

+3) "e"
+ledis> SUNION key1 key2
+1) "a"
+2) "b"
+3) "c"
+4) "d"
+5) "e"

+
+### SUNIONSTORE destination key [key]
+
+This command is equal to SUNION, but instead of returning the resulting set, it is stored in destination.
+If destination already exists, it is overwritten.
+
+**Return value**
+
+int64: the number of elements in the resulting set.
+
+**Examples**
+
+```
+ledis> SMEMBERS key1
+1) "a"
+2) "b"
+3) "c"
+ledis> SMEMBERS key2
+1) "c"

+### SCLEAR key
+
+Deletes the specified set key

+int64: the number of fields in the hash stored at key
+
+**Examples**
+
+```

+1) "a"
+2) "b"
+3) "c"
+4) "d"
+5) "e"
+ledis> SCLEAR key
+(integer) 5
+```
+
+### SMCLEAR key [key ...]

+
+**Examples**

+
+### SEXPIRE key seconds
+
+Sets a set key’s time to live in seconds, like expire similarly.
