1. A method of treating a fabric, said method comprising: a. a washing step, wherein said washing step comprises contacting said fabric with an effective amount of a detergent composition, thereby forming a washed fabric, wherein said detergent composition comprises:i) a surfactant system comprising
1. A method of treating a fabric, said method comprising: a. a washing step, wherein said washing step comprises contacting said fabric with an effective amount of a detergent composition, thereby forming a washed fabric, wherein said detergent composition comprises:i) a surfactant system comprising an anionic surfactant and a nonionic surfactant in a weight ratio of from about 1.1:1 to about 4:1, and wherein said anionic surfactant comprises a linear alkylbenzene sulphonate (LAS) and alkyl ethoxylated sulfate (AES) in a weight ratio of about 0.5:1 to about 1.5:1;ii) a cationic polymer, andiii) a silicone, followed byb. a rinsing step, wherein said washed fabric is contacted with an effective amount of a softener composition, thereby forming a treated fabric, wherein said softener composition comprises a fabric softening active selected from the group consisting of a quaternary ammonium compound, silicone, fatty acids or esters, sugars, fatty alcohols, alkoxylated fatty alcohols, polygvcerol esters, oily sugar derivatives, wax emulsions, fatty acid glycerides, or mixtures thereof. 2. A method according to claim 1, wherein said washing step comprises contacting said fabric with said detergent composition in the presence of water, wherein the detergent composition and the water form a wash liquor. 3. A method according to claim 2, wherein said wash liquor is substantially removed from said washed fabric before said rinsing step occurs. 4. A method according to claim 1, wherein said rinsing step comprises contacting said fabric with said softener composition in the presence of water, wherein the softener composition and the water form a rinse liquor. 5. A method according to claim 1, wherein said weight ratio of anionic surfactant to nonionic surfactant is from about 1.5:1 to about 2.5:1. 6. A method according to claim 1, wherein said weight ratio of anionic surfactant to nonionic surfactant is about 2:1. 7. A method according to claim 1, wherein said cationic polymer is characterized by a weight average molecular weight of from about 5 kDaltons to about 200 kDaltons. 8. A method according to claim 7, wherein said cationic polymer comprises a first structural unit derived from acrylamide, wherein said cationic deposition polymer further comprises a second structural unit derived from DADMAC, and wherein said first structural unit and said second structural unit are in a structural unit ratio of from about 5:95 to about 45:55. 9. A method according to claim 1, wherein said fabric softening active comprises a quaternary ammonium compound selected from the group consisting of: a) linear quaternary ammonium compoundsb) branched quaternary ammonium compoundsc) cyclic quaternary ammonium compoundsd) and mixtures thereof;said quaternary ammonium compounds comprising: one or more C10-C22 fatty acid moieties, C16-C20 fatty acid moieties, or C16-C18 fatty acid moieties, said fatty acid moieties having an Iodine value from 0 to about 95;a counter ion; andone or more moieties selected from the group consisting of alkyl moieties, ester moieties, amide moieties, and ether moieties said one or more moieties being covalently bound to the nitrogen of said quaternary ammonium compound. 10. A method according to claim 9, wherein said fabric softening active further comprises a silicone selected from the group consisting of polydimethylsiloxane (PDMS), aminosilicone, silicone polyether, cationic silicones, silicone polyurethane, silicone polyureas, or mixtures thereof. 11. A method according to claim 1, wherein said detergent composition and/or said fabric softener composition further comprises a perfume microcapsule. 12. A method according to claim 1, wherein said rinsing step results in Silicone Deposition on the treated fabric of from about 80 ug silicone/g to about 5000 ug silicone/g according to the method described herein. 13. A method according to claim 1, wherein said rinsing step results in a Silicone Deposition Index on the treated fabric of from about 4% to about 75%. 14. A method according to claim 1, wherein said anionic surfactant comprises fatty acids and salts thereof. 15. A method according to claim 1, wherein said detergent composition is encapsulated in a pouch, wherein said pouch comprises a water-soluble film. 16. A multi-component fabric treatment system, wherein the system comprises a first component comprising a detergent composition as described in claim 1, and where the system further comprises a second component comprising a softener composition as described in claim 1. 17. A multi-component fabric treatment system according to claim 16, wherein the first component comprises a first container and the second component comprises a second container. 18. A multi-component fabric treatment system according to claim 16, wherein the first component comprises a water-soluble pouch. 19. A multi-component fabric treatment system according to claim 16, wherein the first component and the second component are proximal to each other on a shelf or in a display. 20. A multi-component fabric treatment system according to claim 19, wherein the first and second components are separated by no more than about 100 centimeters.
